(Problems to be solved by the invention) Mounting plate for the control unit case 7 with a screw member 13
When it is mounted on the mounting plate 12, as the screw member 13 rotates, the mounting plate 12 tends to rotate together and tilt as shown in FIG. For this reason, in order to improve the appearance of the mounting plate 12, it requires careful work such as pressing the mounting plate 12 at all times in order to mount it in the up-down direction, and the workability is poor. There is.

The left and right sides (long sides) of the mounting plate 12 have a length with which the locking side 14 engages, while the upper and lower sides have a length less than the opening interval of the tips of the locking side 14, and the upper and lower sides ( It is inserted into the mounting groove 11 with its short side (vertical side) being vertical and rotated by 90 degrees, so that the upper and lower sides are installed at the mounting positions where they engage with the locking pieces 14.

The present invention has been made in view of such problems, and a mounting plate
An object of the present invention is to provide a structure in which the control unit case 7 can be easily attached to the attachment plate 12 via a screw member 13 without inclining the element 12.

(Means for Solving the Problems) The present invention, which has been adopted to achieve the above object, includes an endless body for door opening / closing drive wound around a pair of pulleys, and a drive unit for rotating the pulleys forward and backward. And a case 7 accommodating a control unit for controlling the drive unit, the case body 8 is provided on the inner surface of the rear portion 9 of the case body 8.
A mounting groove 11 is formed along the length direction of the control unit case 7 is mounted on the mounting plate 12 mounted in the mounting groove 11 via a screw member 13, and the control unit case 7 is protruded inside the upper portion of the mounting groove 11. In the mounting structure of the control unit case in which the stop piece 14 is sandwiched between the mounting plate 12 and the control unit case 7, the rotation stop portion of the mounting plate 12 is attached to the side plate 16 of the control unit case 7.
The device 35 is constructed so that the control unit case 7 is screwed to the mounting plate 12 by extending the block 35 and bringing the side edge 36 of the mounting plate 12 into contact with the detent portion 35. Further, the control unit case 7 may be mounted on the upper part of the mounting plate 12.

(Operation) Rotate the screw member 13 to attach the unit case 7 to the mounting groove 11
Even if it is screwed to the mounting plate 12 inside, the side edge 36 of the mounting plate 12 and the detent portion 35 of the side plate 16 of the control unit case 7 abut against each other, and co-rotation of the mounting plate 12 is blocked. Therefore, the mounting plate
The mounting position of 12 does not change during screw connection. Moreover, since the rotation stop portion 35 is simply extended on the side plate 16 of the control unit case 7, the mounting plate 12 does not require any special processing for rotation prevention, and the side edges of the rotation stop portion 35 and the mounting plate 12 are not necessary. The rotation stop of the mounting plate 12 can be easily realized by abutting against the 36.

Further, when the upper part of the mounting plate 12 is screw-coupled, the mounting plate 12 always hangs down in the vertical direction, so that it does not easily change during the screw coupling.

Embodiments Embodiments of the present invention will be described below with reference to the drawings. The basic structure is the same as the conventional one, and common members are denoted by the same reference numerals.

FIG. 1 shows an embodiment of the present invention, in which the case body has a pair of upper and lower L-shaped projections on the inner surface of the rear surface 9 thereof as in the conventional case.
10 and 10 are provided so as to protrude in the lengthwise direction of the case body, and a mounting groove 11 is formed inside thereof. The basic structure of the case body is not limited to that shown in FIG. For example, the lower surface portion 22 having the rail portion 21 does not have to be formed integrally with the case body 8, and is attached to the rear surface portion 9 with a bolt or the like.
It may be detachably provided.

Steps 34 that engage with the opening edges of the mounting groove 11 are formed along the length direction above and below the back surface 31a of the case body 31. A mounting piece portion 15 extending along the length direction is bent and formed in a substantially central portion of the side plate 16, and a screw 13 penetrates a screw insertion hole 17 formed in the mounting piece portion 15, It is screwed into a screw hole 18 formed in a mounting plate 12 mounted in the mounting groove 11. At the lower part of the side plate 16, there is formed a detent portion 35 projecting from the rear surface of the case main body. By engaging and abutting the side edge 36 of the mounting plate 12, both sides of the mounting plate 12 generated when the screw 13 is coupled are formed. Stop the surroundings.

When the screw 13 is a right-hand screw, the rotation stopping portion 35 is formed on the lower part of the side plate 16 on the right side in front view of the control unit case, but is formed on the upper side on the left side. However, rotation stoppers may be provided on both upper and lower parts of the side plate 16, and the case body
The stepped portion 34 of the back surface portion 31a of 31 may be enlarged so as to be immersed in the mounting groove 11.

FIG. 3 shows a main part of another embodiment of the present invention.
The mounting piece 15 is formed on the upper part of the 16 while the
The screw hole 18 of the mounting plate 12 is also opened in the upper part corresponding to the screw insertion hole 17 of the mounting piece portion 15. With this configuration,
The mounting plate 12 always hangs down due to its own weight, making it difficult to rotate together. Although the detent portion is not shown in the figure, as described above, the detent portion is on a part or all of the edge of the side wall 16 of the control unit case on the side of the mounting groove 11 except the mounting piece 15. You can extend it.

(Effects of the Invention) As described above, according to the present invention, since the control unit case or the mounting plate is provided with the rotation preventing portion that abuts each other, there is no co-rotation at the time of screw fastening, and the control unit case is mounted on the mounting plate. Can be securely fastened with the locking piece in between,
Workability is also good. Moreover, since the detent portion is simply extended to the side plate of the control unit case, the mounting plate does not require any special processing for detent, and the rotation of the mounting plate is prevented by the contact between the detent portion and the mounting portion. It can be stopped very easily and has excellent workability.

Further, by screwing the control unit case to the upper portion of the mounting plate, the mounting plate is hung down by its own weight, so that co-rotation hardly occurs and workability is improved.
