Description

  The present invention relates to a drag knob, and more particularly to a drag knob that adjusts the drag force of a drag mechanism by being screwed into a front end of a spool shaft on which a spool of a spinning reel is mounted.

  Generally, in a front drag type spinning reel, a drag disk of a drag mechanism is accommodated in a spool. The drag force of the drag disk is adjusted by a drag knob screwed onto the spool shaft. The spool is rotatably attached to the tip of the spool shaft, and at least one of the drag disks is non-rotatably attached to the spool shaft. The spool is formed with a cylindrical recess for storing the drag disk on the front end surface. In order to prevent the drag disk housed in the recess, an annular groove formed on the front side of the recess, for example, by machining, and a spring member formed by bending a metal elastic wire into a polygonal shape are conventionally provided. It is used. In the conventional drag disk retaining structure, the corners of the spring member are locked to the annular groove, and the straight part between the corners is brought into contact with the drag disk to prevent the drag disk from slipping.

  The drag knob includes a synthetic resin knob main body screwed onto the spool shaft, and a synthetic resin pressing member that is non-rotatably mounted on the spool shaft and presses the drag disk. The knob body is integrally formed by molding in the front-rear direction. The knob body is a disk-like member, and an operation drag knob is formed on the front end surface so as to protrude along the diameter, for example. A recess is formed in the rear end surface of the knob body, and at least a part of the pressing member is accommodated in the recess. The pressing member is a columnar member having a large-diameter collar, and the collar is housed in the recess and is prevented from being detached by the spring member, so that the knob body and the pressing member move back and forth integrally.

In a drag mechanism having such a drag knob, generally, when the drag disk gets wet, the frictional force varies, and the drag force changes even when the drag knob is at the same position. Therefore, it is known that an elastic resin sealing member is attached between the pressing member and the spool in front of the drag disk so that water does not enter the drag disk from the outer peripheral side of the drag knob (for example, Patent Document 1). This type of seal member is formed with a large diameter because the gap between the pressing member and the spool is relatively large. For this reason, a reinforcing member made of stainless steel is insert-molded inside the elastic resin.
JP 11-196729 A

  The sealing member of the conventional spinning reel has a reinforcing member made of stainless steel that is insert-molded inside the elastic resin, so that it does not expand and contract in the radial direction, so that the mounting position of the sealing member is limited. There is a concern that the manufacturing cost may be increased as compared with a sealing member formed of only a general elastic resin.

  Therefore, a sealing member made of an elastic resin is attached to the annular groove formed by machining on the outer periphery of the drag knob in front of the drag disk so that water does not enter the drag disk between the drag knob and the spool. It is possible. Since this seal member has a relatively small gap between the drag knob and the spool, there is no need to insert a reinforcing member made of stainless steel into the elastic resin. In addition, since the elastic resin seal member is attached to the groove portion of the drag knob, the attachment of the seal member is facilitated.

  However, since such a drag knob is integrally formed by molding in the front-rear direction, it is necessary to form the groove for mounting the seal member by post-processing such as cutting. For this reason, it takes time to process the drag knob, and an increase in the number of manufacturing steps may cause an increase in manufacturing cost.

  The subject of this invention is suppressing the increase in manufacturing cost in the drag knob of a spinning reel.

  A drag knob of a spinning reel according to a first aspect of the present invention is a drag knob that adjusts the drag force of a drag mechanism by screwing with a front end of a spool shaft on which a spool of the spinning reel is mounted, and a knob that adjusts the drag force by hand. The front part outer periphery of the rear end part of the storage part that passes through the front and rear of the storage part and the storage part in which the rear part is formed integrally with the rear part of the rear part and the rear part of the storage part are integrally formed. A knob body having a plurality of groove portions formed in a substantially arc shape by molding so as to be recessed from the outer periphery of the rear end portion of the portion, a nut member that is non-rotatably attached to the housing recess and screwed into the tip of the spool shaft, A cylindrical pressing member that is partially stored in the storage recess and presses the drag disk of the drag mechanism, and a biasing member that is provided between the nut member and the pressing member and biases the pressing member in a direction away from the nut member. A gap between the spool and the knob main body, the retaining member for retaining the pressing member from the housing recess, and the inner peripheral side closely contacting the outer peripheral portion of the groove portion and the outer peripheral side closely contacting the inner peripheral portion of the spool. And a seal member for sealing.

  In this drag knob, the knob main body is formed with a groove portion that passes through the front and rear of the housing portion and the flange portion by molding in the front-rear direction, and in which a seal member is mounted. Here, since the groove portion is integrally formed by molding in the front-rear direction, there is no need to perform post-processing such as cutting as in the prior art. Accordingly, the knob main body can be easily formed, and the number of manufacturing steps does not increase, so that an increase in manufacturing cost can be suppressed.

  The drag knob according to a second aspect of the present invention is the drag knob according to the first aspect, wherein a notch portion formed by molding so that at least a part of a rear end portion where the groove portion of the storage portion is not formed is notched, and a notch And a washer with an ear that contacts the rear end side of the seal member. In this case, the backward movement of the seal member can be restricted, and the seal member can be prevented from being distorted or deformed.

  The drag knob according to a third aspect of the present invention is the drag knob of the second aspect, wherein the retaining member is a spring member that is attached to the outer peripheral portion of the groove portion and presses the ear portion of the washer with the ear. The pressing member has a flange portion that is formed so that the end portion on the side of the storage recess has a larger diameter than the other portion and is prevented from coming off by a washer with an ear. In this case, the backward movement of the seal member and the pressing member can be simultaneously and easily controlled by the washer with the ear and the spring member.

  A drag knob according to a fourth aspect of the present invention is the drag knob according to any one of the first to third aspects, wherein the pin member that is detachably attached to the storage portion and the concave portion formed on the front end side of the flange portion are repeatedly brought into contact with each other. And a drag sound generation mechanism having a plurality of recesses for generating sound. In this case, when the drag knob is rotated, the pin member repeatedly makes contact with the plurality of recesses and generates a sound, so that a comfortable click feeling can be given when the drag knob is rotated.

  The drag knob according to a fifth aspect is the drag knob according to any one of the first to fourth aspects, wherein the seal member has a pair of engaging portions formed so that the inner peripheral side contacts the groove portion. In this case, for example, a pair of engaging protrusions formed so as to protrude so that the inner peripheral side comes into contact with the groove portion as the engaging portion is engaged with the groove portion, or formed so as to be recessed so that the inner peripheral side comes into contact with the groove portion. By engaging the pair of engaging recesses with the groove, the seal member can be prevented from rotating with respect to the knob body.

  A drag knob according to a sixth aspect of the present invention is the drag knob according to any one of the first to fifth aspects, wherein the seal member has a lip portion formed such that the tip of the outer peripheral portion is pointed radially outward. In this case, since the sealing member has a lip portion having a tapered cross section at the contact portion with the spool, the contact area with the spool is reduced, and the rotational resistance when the spool rotates relative to the spool shaft is increased. Can be suppressed.

  According to the present invention, in the drag knob of the spinning reel, the groove portion of the knob main body is integrally formed by molding in the front-rear direction, so that an increase in manufacturing cost can be suppressed.

The knob body 66 is not formed with a notch 66f for mounting the washer 64 with ears of the embodiment.

  As shown in FIGS. 8 and 10, the retaining member 67 is a member formed by bending an elastic metal wire. The retaining member 67 is formed so as to be compressed into a quadrangle when attached, and to be slightly expanded when not attached. The rectangular corner 67a of the retaining member 67 protrudes radially outward from the flange 65a of the pressing member 65 and is locked to the forming end of the locking groove 66h, and the contact portion 67b connecting the corner 67a is the pressing member. It contacts the rear surface side of 65 flange portions 65a. As a result, the pressing member 65 is stored in a state in which the pressing member 65 is prevented from being detached from the knob body 66.

Here, the retaining member 67 bent so as to have a quadrangular shape can reliably prevent the pressing member 65 from being detached from the knob body 66 with a simple configuration.
(C) In the embodiment, the rotation of the seal member 63 with respect to the knob body 66 is restricted by engaging the engaging recess 63d with the groove 66d. However, as shown in FIGS. You may make it the structure which controls rotation in the front-back direction with respect to the knob main body 66 by engaging a pair of engaging protrusion 63c with the groove part 66d. In this case, the longitudinal length of the groove portion 66d formed in the storage portion 66c is formed to be substantially the same as the thickness of the seal member 63, and the width of the groove portion 66d formed in the storage portion 66c is It is formed so as to be substantially the same as the width of the engaging protrusion 63 c of the seal member 63.

  Here, it is possible to easily restrict the rotation of the seal member 63 relative to the knob body 66 and the movement in the front-rear direction.
