Description

  The present invention relates to a surveillance camera device that is used by installing a camera housed and held in a camera case body in a horizontal state on a desk or the like via a fixed base, or by locking it to a wall surface or the like and installing it in a vertical state. .

  Conventionally, as this type of surveillance camera device, for example, surveillance camera devices described in Patent Documents 1 to 3 have been proposed.

  The surveillance camera device described in Patent Literature 1 is configured to easily adjust the depression angle of the imaging unit in a state of being fixed at the installation position, and includes an operation unit for adjusting the depression angle. As shown in FIG. 16, the operation unit 101 has a cross-shaped fitting groove 102 formed at the tip of a rotating shaft (not shown). A tool such as a cross driver (not shown) is inserted into the fitting groove 102 and rotated. Thus, a rotating shaft (not shown) can be rotated. The rotation axis is provided with a display unit 103 for representing the depression angle state of the imaging unit based on the depression angle variable of the imaging unit. The display unit 103 is formed in a disk shape that rotates with the rotation shaft. On the surface of the display unit 103, a display indicating the state of the depression angle of the imaging unit is provided, and an index unit 104 is provided at a position in the vicinity of the display unit 103. The indicator unit 104 indicates the display on the display unit 103 corresponding to the current state of the depression angle of the imaging unit that is changed by the operation unit 101. Thus, for example, when the index unit 104 points to “up” of the display unit 103, it is possible to confirm at a glance that the depression angle of the imaging unit is facing upward (horizontal direction). It has become.

  As shown in FIG. 17, the surveillance camera device 201 described in Patent Document 2 includes a case 202, a pan rotation shaft 204 that rotates around a pan rotation center shaft 225 by a pan motor 203 fixed to the case 202, and a pan A tilt rotation center shaft 226 is attached to a horizontal swivel 205 attached to the upper end of the rotary shaft 204 and capable of swiveling in a horizontal plane, and a tilt motor 206 attached to a bent portion 205a bent upward at a side end of the horizontal swivel 205. And a camera 210 provided on a U-shaped holder 208 having a camera lens 209 and an electrification coupling element (CCD) 220 and fixed to the tilt rotation shaft 207. The camera 210 and the like are housed in a cylindrical case 228 and a translucent dome cover 227 provided thereon.

  In addition, as shown in FIGS. 18A and 18B, the surveillance camera device described in Patent Document 3 has an installation place 307 installed via a fixed plate 301 and a rotating plate 302 that is not flat but oblique. When tilted, the camera case 308 is removed, the fixing band 313 that fastens and fixes the turntable 312 is loosened, and the turntable 312 that covers and fixes the TV camera 305 is connected to the TV camera 305. By rotating and adjusting while watching the video, the level of the imaging surface of the television camera 305 can be maintained. Since the optical axis of the TV camera 305 is set to the center of the cylinder of the turntable 312, the optical axis of the TV camera 305 is rotated around the center of the optical axis of the TV camera 305, ie, the center of the cylinder. The tilt can be adjusted to keep the degree.

In addition to this, although not shown in the drawings, there has been proposed a pan head apparatus that can attach the rotated body to a position with a smaller rotational load (see, for example, Patent Document 4). In this pan / tilt head device, the pedestal is slidable and fixed at an arbitrary position so as to be movable vertically and horizontally.

  According to Patent Document 1, it is possible to know the depression angle of the imaging unit from the position of the character on the display unit 103 indicated by the index unit 104. That is, the display unit 103 is rotated only to indicate the depression angle of the imaging unit. For example, a display unit such as a 7-segment LED for displaying the device state is provided on a fixed base of the imaging unit. In some cases, the display unit is not adjusted so as not to tilt with respect to the imaging unit.

  According to Patent Document 2, the camera 201 can be rotated in the horizontal direction (pan direction) and the vertical direction (tilt direction). However, as a usage form of the monitoring camera device described in Patent Document 1, a configuration in which the surveillance camera device is installed on a desktop or the like or used on a ceiling or the like, that is, the device itself is in a horizontal state. It is limited to the form of installation and use, for example, it cannot be installed on a vertical wall surface or the like and used in a vertical state (a state directed in the lateral direction). In other words, when installed on a vertical wall or the like, the top and bottom direction of the photographed image cannot be secured, and when the tilt direction is adjusted, the top and bottom of the photographed image is slanted or reversed. There was a problem that it was very difficult to see as an image. Furthermore, since it cannot be installed and used on a vertical wall surface, there is a problem that the place of use is limited to the desktop or the ceiling.

  Further, according to Patent Document 3, it is possible to secure the top-and-bottom direction of the TV camera 305 even when the installation location is inclined obliquely. This means that the top and bottom direction of the television camera 305 can be secured regardless of the direction in which the surveillance camera device is installed regardless of the horizontal direction and the vertical direction. However, in Patent Document 3 described above, in order to secure such a top-and-bottom direction of the TV camera 305, the camera case 308 is removed, the fixing band 313 that fastens and fixes the turntable 312 is loosened, and the TV camera 305 is covered. Therefore, it is necessary to perform troublesome work such as adjusting the rotating base 312 while watching the video of a monitor (not shown) connected to the TV camera 305. Further, such a work is required every time the elevation angle of the television camera 305 is adjusted thereafter, and there is a problem that it is a very complicated work for the user.

  In addition, the structure of the pan / tilt head device described in Patent Document 4 is such that the camera housed and held in the camera case main body is placed horizontally on a table or the like via a fixed base, or locked to a wall surface or the like to be vertical. This structure is not suitable for a surveillance camera device installed and used in a state.

  The present invention was devised to solve such problems, and its purpose is simple even if it is installed in a horizontal state on a tabletop or the like, or locked in a wall or the like and installed in a vertical state. An object of the present invention is to provide a surveillance camera device that can ensure the top-and-bottom direction of a photographed image by operation. In addition, even when the camera is rotated in the horizontal direction with respect to the fixed base, the display direction of the display section is also adjusted by rotating the display section provided on the fixed base in conjunction with the rotation. It is an object of the present invention to provide a surveillance camera device capable of displaying in the vertical direction in which (the display direction when the user faces the camera) always matches the direction of the camera (top and bottom direction).

  The surveillance camera device of the present invention is used by installing a camera housed and held in a camera case body in a horizontal state on a desktop or the like via a fixed base, or by locking it to a wall surface or the like and installing it in a vertical state. It is a surveillance camera device. That is, the surveillance camera device is assumed to be used in any one of the two positions of the horizontal state and the vertical state. This surveillance camera device is connected to the camera case main body and can adjust the vertical elevation angle of the camera, and the vertical elevation rotation unit can be connected to the vertical elevation rotation unit and can rotate in the horizontal direction. A base rotation unit provided on the upper surface of the fixed base and rotatable in the horizontal direction; a display unit provided on the upper surface of the fixed base and rotatable in the horizontal direction; the base rotation unit and the display unit; An interlocking rotating part that rotates in conjunction with each other, and an arm member having one end fixed to the horizontal rotating part and the other end connected continuously to the base rotating part in one direction. The base rotation unit and the display unit are provided so that the front-rear direction of the base rotation unit and the vertical direction of the display unit always coincide with each other by rotating the base rotation unit and the display unit by the interlocking rotation unit. To do.

  With such a configuration, for example, when the base rotation unit is rotated 90 degrees in the horizontal direction in order to change the fixed base that was horizontally placed on the table to the vertical position, the display unit is also moved in the same direction. It rotates 90 degrees, and the front-rear direction of the base rotation unit and the vertical direction (display direction) of the display unit always coincide. Therefore, when the user looks at the display unit while facing the camera housed in the camera case body, the vertical direction (display direction) of the display unit is always secured, so the display content can be accurately It can be read.

  In this case, the interlocking rotation unit may be configured by a combination of a plurality of gears. By adopting such a mechanism structure with gears, the rotation of the base rotation unit and the display unit can be synchronized with a simple configuration. The base rotating portion may be provided with a base fixing means for fixing the rotational position in the horizontal direction at an arbitrary position. By providing such a fixing means, the base rotating part that holds the camera can be held in a stable state without rattling.

  Further, according to the surveillance camera device of the present invention, the rotating shaft of the horizontal rotating unit can be provided in a state where the fixed base is installed in a horizontal state at the connecting portion between the other end side of the arm member and the base rotating unit. Position fixing means for fixing at a first rotation position for vertically supporting and at a second rotation position for vertically supporting the rotation shaft of the horizontal rotation portion in a state where the fixing base is installed in a vertical state. The position fixing means does not fix the arm member between the two rotation positions.

  With such a configuration, when the surveillance camera device is installed on a desktop or the like and used in a horizontal state, for example, the arm member is rotated to the first rotation position, and the first fixing is performed by the position fixing means. The arm member is fixed at the moving position. As a result, the rotation axis of the horizontal rotation unit can be supported vertically, so that even if the vertical elevation rotation unit is rotated in this state, the captured image is captured with the top-to-bottom direction secured. . Similarly, when the surveillance camera device is installed on, for example, a vertical wall surface and used in a vertical state, the arm member is rotated to the second rotation position, and the position fixing means is used at the second rotation position. Fix the arm member. As a result, the rotation axis of the horizontal rotation unit can be supported vertically, so that even if the vertical elevation rotation unit is rotated in this state, the captured image is captured with the top-to-bottom direction secured. . That is, according to the surveillance camera device of the present invention, the top-to-bottom direction of the captured image after the elevation angle adjustment is reliably ensured in both the horizontal state installed on the tabletop and the vertical state installed on the vertical wall surface. It becomes possible.

  In this case, the horizontal rotating portion includes a cylindrical rotating support fixed to one end of the arm member, and a cylindrical rotating body that rotates in the horizontal direction while being externally fitted to the rotating support. The rotation support body and the rotation body are provided with stopper means for restricting the rotation of the rotation body to a predetermined rotation angle range. The stopper means includes a first stopper means provided on the outer surface of the rotating support and the rotating body and a second stopper means provided on the inner surface of the rotating support and the rotating body. The first stopper means and the second stopper means are provided at positions that simultaneously restrict the rotation of the rotating body.

  If the rotation angle range of the camera in the horizontal direction, including the angle of view of the camera, can be secured within a rotation angle range of about 180 degrees, the entire room can be photographed. In this case, when a wide-angle lens of about 60 degrees is used as the angle of view of the camera, the rotation angle range may be about 60 degrees. Accordingly, in this case, the first stopper means is provided on the outer surface of the rotating support and the rotating body at an angle of about 60 degrees when viewed from the rotation center of the horizontal rotating portion, and the second stopper means is disposed horizontally. The rotating support and the inner surface of the rotating body are provided at an angle of about 60 degrees when viewed from the rotation center of the rotating portion. In this way, by providing the stoppers for regulating the rotation angle range in the horizontal direction at the two locations of the rotating support and the outer surface and the inner surface of the rotating member, stable rotation is controlled without rattling. be able to.

  Moreover, the rotating body which is a cylindrical member is usually formed of resin or the like by injection molding or the like. Therefore, there is also a problem in molding, and the rotating body having such a shape is usually divided into two parts on the left and right, and the rotating body is formed by assembling these divided bodies integrally. In this case, when the stopper means is provided only on the rotation support body and the inner surface of the rotation body, an excessive load is applied to the inside of the left and right divided bodies due to the rotation body hitting the stopper means many times. Therefore, there is a possibility that the divided body will be separated due to long-term use. However, as in the present invention, stopper means (first stopper means) are also provided on the rotating support and the outer surface of the rotating body. Thus, the problem that the divided bodies are separated can be solved. In particular, in the present invention, the first stopper means is configured to restrict the rotation so that both divided bodies are pressed against each other when the rotation of the rotating body is restricted. can do.

  Since the surveillance camera device of the present invention is configured as described above, when the base rotation unit is rotated 90 degrees in the horizontal direction, for example, the display unit is also rotated 90 degrees in the same direction. The direction and the vertical direction (display direction) of the display unit always coincide. Therefore, when the user looks at the display unit while facing the camera housed in the camera case body, the vertical direction (display direction) of the display unit is always secured. Even if it is installed in such a state, the display content of the display unit can be accurately read.

  In addition, according to the surveillance camera device of the present invention, the top-to-bottom direction of the photographed image after the elevation angle adjustment is reliably ensured in both the horizontal state installed on a tabletop and the vertical state installed on a vertical wall surface. be able to. Moreover, since the stopper for restricting the rotation angle range in the horizontal direction is provided at the two locations of the rotation support body and the outer surface and the inner surface of the rotation body, stable rotation restriction can be performed without rattling. it can. Furthermore, when the rotating body is formed by integrally assembling the left and right divided bodies, a stopper for regulating the horizontal rotation angle range is provided on the rotating support body and the rotating body. Provided in two places on the outer side and inner side, and when the rotation of the rotating body is restricted, it is configured to restrict the rotation so that both divided bodies are pressed against each other. Therefore, it is possible to provide a surveillance camera apparatus that can be used for many years.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 and 3 are perspective views showing the overall configuration of the surveillance camera device of this embodiment, and FIG. 2 is a side view of the surveillance camera device in the state shown in FIG. FIG. 1 shows a state in which the surveillance camera device is horizontally installed on a tabletop or the like, and FIG. 3 shows a state in which the surveillance camera device is vertically installed on a vertical wall surface using a not-shown locking tool or the like. Show.

  The surveillance camera device 1 according to the present embodiment has a camera case body 2 in which a camera (not shown) is stored and held in a horizontal state on a tabletop or the like via a fixed base 4 or is locked to a vertical wall surface or the like in a vertical state. The vertical elevation angle rotation unit 10 connected to the camera case main body 2 and adjustable in the vertical elevation angle of the camera (the arrow Y direction in FIG. 2), and the vertical elevation angle rotation unit 10 Are provided on the upper surface 42 of the fixed base 4 and the horizontal rotating part 20 that is connected to the horizontal rotation unit 20 and is rotatable in the horizontal direction (the arrow X direction in FIG. 1, the direction perpendicular to the paper surface in FIG. 2). 1, a disc-shaped base rotating unit 60 that can rotate in the direction of arrow X, and a display unit 80 that is provided on the upper surface 42 of the fixed base 4 and that can rotate in the horizontal direction (in the direction of arrow X in FIG. 1). And the upper end 51 side is fixed to the horizontal rotating part 20, and the lower end 52 side is the base rotating part. (In FIG. 1 and FIG. 2, arrow Z direction) in one direction relative to the 0 consists in rotatably provided continuously an arm member 50..

  The fixed base 4 is formed in a flat rectangular parallelepiped shape, and a control circuit board for controlling a detection sensor and the like housed in the camera or the camera case body 2 although not shown therein. Is stored. Further, leg pieces 41 are formed at the four corners of the lower surface of the fixed base 4.

  FIG. 4 is a partially enlarged cross-sectional view illustrating an example of a structure in which the base rotating unit 60 is rotatably fitted to the upper surface 41 of the fixed base 4.

  A circular first opening 48 for rotatably fitting the base rotating portion 60 is provided at the center of the upper surface of the fixed base 4. An annular lateral groove 61 that fits around the peripheral edge of the one opening 48 is formed.

  In other words, the base rotating portion 60 includes a disk-shaped upper base portion 62 that is slightly curved upward, and a lower base portion 63 that is formed in a ring shape. An annular protrusion 64 is formed at the center side. The outer peripheral shape of the annular protrusion 64 is formed in a shape that can be rotated in a state of being fitted to the first opening 48 formed in the fixed base 4. Then, with the annular protrusion 64 fitted into the first opening 48 of the fixed base 4, the lower base part 63 is brought into contact with the lower base part 63, and the screw is connected to the annular protrusion 64 from below the lower base part 63. The upper base part 62 and the lower base part 63 are integrally assembled by screwing a fixture 65 such as a screw. That is, the annular lateral groove portion 61 is formed by the annular protrusion 64 and the outer peripheral lower surface of the upper base portion 62 and the outer peripheral upper surface of the lower base portion 63 protruding outward from the annular protrusion 64. As described above, the peripheral portion of the first opening 48 is sandwiched between the upper base portion 62 and the lower base portion 63 from above and below, thereby preventing the base rotating portion 60 from coming off from the fixed base 4. A plurality of fixtures 65 (for example, four) are attached along the annular protrusion 64 at a predetermined interval.

  A cylindrical projection 66 protruding downward is formed on the inner peripheral portion of the lower base portion 63, and a drive gear 71 is attached to the lower portion of the cylindrical projection 66.

  On the other hand, a circular second opening 49 for rotatably fitting the display unit 80 is provided on one side of the upper surface of the fixed base 4, and a disc-shaped holding case for holding the display unit 80. An annular lateral groove 82 that fits around the peripheral edge of the second opening 49 is formed on the entire outer periphery of 81.

  That is, the holding case 81 includes an upper case portion 83 that holds the display portion 80 and a lower case portion 84 that is formed in a ring shape, and the lower surface of the upper case portion 83 is slightly centered from the peripheral edge thereof. An annular projecting portion 85 is formed where it enters. The outer peripheral shape of the annular protrusion 85 is formed in a shape that can be rotated in a state of being fitted to the second opening 49 formed in the fixed base 4. Then, with the annular protrusion 85 fitted into the second opening 49 of the fixed base 4, the lower case part 84 is brought into contact with the lower part 84 from below, and a screw is attached to the annular protrusion 85 from below the lower case part 84. The upper case portion 83 and the lower case portion 84 are integrally assembled by screwing a fixture 86 such as a screw. That is, the annular lateral groove portion 82 is formed by the annular protrusion 85 and the outer peripheral lower surface of the upper case portion 83 and the outer peripheral upper surface of the lower case portion 84 projecting outward from the annular protrusion 85. As described above, the peripheral portion of the second opening 49 is sandwiched between the upper case portion 83 and the lower case portion 84 from above and below, thereby preventing the holding case 81 from coming off from the fixed base 4. A plurality of fixtures 86 (for example, four) are attached at predetermined intervals along the annular protrusion 85.

  A cylindrical projection 87 protruding downward is formed on the outer peripheral portion of the lower case portion 84, and a driven gear 73 is attached to the lower portion of the cylindrical projection 87.

  An idle gear 72 is attached to the lower portion of the upper surface 42 of the fixed base 4 between the first opening 48 and the second opening 49 by a support shaft 74. The idle gear 72 meshes with a drive gear 71 attached to the lower part of the base rotating part 60 and a driven gear 73 attached to the lower part of the display part 80, and the rotation of the drive gear 71, that is, the base rotating part. The rotation of 60 is transmitted to the driven gear 73 of the display unit 80. That is, the interlocking rotation unit described in the claims is constituted by the drive gear 71, the idle gear 72 and the driven gear 73.

  Here, if the drive gear 71 and the driven gear 73 have the same diameter, and the number of gear teeth and the pitch thereof are set to be the same, the base rotation unit 60 and the display unit 80 have the same angle in the same direction. Will rotate.

  That is, as shown in FIG. 5A, when the fixed base 4 is installed on a wall surface in a horizontally long state, for example, the display “A” on the display unit 80 is also displayed vertically without being tilted as shown in the figure. In this case, if the base rotating unit 60 is rotated 90 degrees to the right and the fixed base 4 is installed on the wall surface in a vertically long state as shown in FIG. 5B, the display unit 80 is also linked to this. Since the image is rotated 90 degrees in the direction, the display “A” on the display unit 80 is also displayed in the vertical direction without being tilted as illustrated. Similarly, when the base rotating unit 60 is rotated 60 degrees to the right from the state shown in FIG. 5A, and the fixed base 4 is installed on the wall surface obliquely as shown in FIG. Since the display unit 80 is also rotated 60 degrees in the same direction, the display “A” on the display unit 80 is also displayed in the vertical direction without being tilted as illustrated.

  As described above, according to the monitoring camera device 1 of the present embodiment, when the base rotation unit 60 is rotated in the horizontal direction, the display unit 80 is also rotated at the same angle in the same direction. The front-rear direction and the vertical direction (display direction) of the display unit 80 always coincide. Therefore, when the user views the display unit 80 while facing the camera housed in the camera case body 2, the display unit 80 always maintains the vertical direction without being tilted when viewed from the user. Therefore, the display content can be easily read regardless of the direction in which the monitoring camera device 1 is installed. In addition, although 7 segment LED is used as the display part 80 in this embodiment, it is not limited to this.

  FIG. 6 is a cross-sectional view taken along the line AA of FIG. 4 and shows an example of a base fixing means for fixing the base rotating portion 60 at an arbitrary rotational position in the horizontal direction (restricting rotation).

  That is, a plurality of concave groove portions 64 a are formed on the outer peripheral surface of the annular protrusion 64 of the base rotating portion 60 with a certain interval, and the periphery of the first opening 48 facing the annular protrusion 64. On the end face, a plurality of small projections 48a that fit into the concave groove 64a are formed at a constant interval. In the example shown in FIG. 5, four concave grooves 64a and four small protrusions 48a are formed at intervals of 90 degrees. However, for example, as shown in FIG. 5C, the base rotating part 60 is rotated 60 degrees. 12 may be fixed (rotation restricted) by forming twelve grooves 64a and small protrusions 48a at intervals of 30 degrees. In addition, what is necessary is just to determine suitably the number which provides the groove part 64a and the small protrusion part 48a as needed.

  By providing such a base fixing means, the base rotating portion 60 that holds the camera can be held at each rotational position in a stable state without rattling.

  Note that the depth of the concave groove portion 64a and the protrusion of the small protrusion portion 48a are such that the engagement force between the concave groove portion 64a and the small protrusion portion 48a becomes an engagement force that can be removed by applying a slight force to the base rotating portion 60. Set the length. In this case, when the base rotating portion 60 is formed of a resin having a certain degree of elasticity to apply a rotational force to the base rotating portion 60, the small protruding portion 48a becomes an annular protruding portion after the engagement is released. It will be in the state which contacted the outer peripheral surface of 64, and will rotate in the state which the cyclic | annular protrusion part 64 deform | transformed slightly with the elastic force of resin itself. That is, even if the small protruding portion 48a is not necessarily fitted in the concave groove portion 64a, the small protruding portion 48a comes into contact with the outer peripheral surface of the annular protruding portion 64 with a slight pressure contact force, so that the base rotating portion 64 can be arbitrarily set. It can be fixed in position.

  FIG. 7 shows another embodiment of the base fixing means. That is, a gear structure 64b in which triangular protrusions are formed at a constant pitch n is formed on the entire outer peripheral surface of the annular protrusion 64, and a spring body 88 having a triangular engagement portion 88a fitted between the protrusions. It is good also as a structure which fixed the base end part 88b side to the upper surface lower part of the fixed stand 4 which is not shown in figure. With such a structure, when the base rotating portion 60 is rotated, it can be fixed (rotation restricted) in multiple stages for each pitch interval n of the protrusions.

  FIG. 8 shows a structure of a fitting portion for connecting the lower end portion 51 of the arm member 50 to the base rotating portion 60 provided on the fixed base 4 so as to be rotatable. It is a perspective view in the state where member 50 was removed. FIG. 9 is a sectional view taken along line BB in FIG.

  On the upper surface of the arm rotating portion 60, there is an arm fitting portion 43 having a rectangular parallelepiped shape that is long in the lateral direction (vertical direction in FIG. 8) for connecting the lower end portion 51 of the arm member 50 to the central portion in a rotatable manner. The rotation shaft 45 that is the rotation center P <b> 1 of the arm member 50 protrudes from the opposing surfaces 44 of both end portions in the longitudinal direction of the arm fitting portion 43 (upper end portion and lower end portion in FIG. 4). Is formed.

  Further, a pair of left and right guide pieces 46a and 46b that are concentrically curved with the rotation shaft 45 are formed on the facing surface 44 so as to protrude from the rotation surface 45 of the guide pieces 46a and 46b. Arm fixing groove portions 46a1 and 46b1 extending along the axial center direction of the rotating shaft 45 are formed at appropriate positions on the curved surface (guide surface) side. These arm fixing groove portions 46a1 and 46b1 are formed at positions at a certain angle (90 degrees in this example) with the rotation center P1 of the rotation shaft 45 as a vertex.

  Further, as shown in FIG. 9, at both ends in the short direction of the arm fitting portion 43 (left and right end portions in FIG. 8), a certain angle (90 degrees in this example) from the rotation center P1 of the rotation shaft 45. In this way, inclined surfaces 47a and 47b extending radially are formed. The inclined surfaces 47a and 47b function as a stopper for restricting the rotation range of the lower end 51 of the arm member 50 described later between a first rotation position and a second rotation position described later. .

  FIG. 10 is a perspective view showing the horizontal rotating portion 20 and the arm member 50 in a state where they are continuously provided.

  The arm member 50 has a shape that is gently curved as a whole from the lower end portion 52 toward the upper end portion 51, and the lower end portion 52 has a cylindrical shape that fits into the arm fitting portion 43 of the arm rotating portion 60. It is a rotating part (hereinafter also referred to as “cylindrical rotating part”). The cylindrical rotating portion 52 has annular recesses 53 (only the front side is shown in FIG. 6) that fits on the rotating shaft 45 formed on the arm rotating portion 60 side on each of both end faces in the longitudinal direction. ) Is formed. Further, a rectangular parallelepiped contact plate 55 is formed at the lower portion of the cylindrical rotating portion 52 at the center in the longitudinal direction, and at both ends in the longitudinal direction except for the contact plate 55 in the longitudinal direction. An arm fixing projection piece 56 extending along the axis is formed.
