る。 Next, attachment of the brake lever 15 will be explained. The supporting end 17 of the lever 15 is attached to the bracket 5.
When rotatably supporting the lever 15 in the support hole 12 on the upper surface, first rotate the lever 15 90 degrees counterclockwise as shown in FIG.
1 and the protrusion 20 are aligned with the support hole 12, then inserted into the support hole 12, rotated 90 degrees clockwise, and returned to the original position. Then, the protrusion 20 is inserted into the circular hole 13.
The engagement piece 2 is rotatably supported along the inner peripheral edge of the engagement piece 2.
1 and 21 overlap and engage with the periphery of the lower surface of the circular hole 13, and the frame side 19 overlaps and engages with the upper surface around the support hole 12, thereby rotating the support end 17 into the support hole 12 on the upper surface of the bracket 5. It can be pivoted freely and prevented from falling off. After supporting the supporting end 17, the wire 10 is connected to the driving end 16 of the lever 15.
The spring 8 is then fixed.

１５全体を時計方向に90度回転させるのである。 In this embodiment, the dimensions of each part of the support hole 12 and the support end 17 were set as a<a', b<b', and c<c'.
If a>a' or c>c', or a>a' and c>
In the case of c', from one engagement piece 21 to the circular hole 13
the other engaging piece 21 and move it to the lower surface of the relief hole 14 (from the right side to the left side in FIG. 3).
After inserting the lever 15 into the circular hole 13 until the end, the lever 15 is returned a little so that the protrusion 20 is aligned with the circular hole 13, and then the entire lever 15 is rotated 90 degrees clockwise.
又、本実施例では支持部を支持孔１２として、
支持端１７に突部２０等を設けているが、支持部

り、工程上のコストを減少することができる。 In this way, the motor brake device according to the present invention has a support part on the other side of the top surface of the motor, and the support end of the brake lever is rotatably supported on this support part, so that the brake stand can be placed on one side of the top surface of the motor. Since it is only necessary to provide a shaft support and no shaft support is required, it is possible to downsize and reduce material costs. In addition, since the supporting end and the supporting part are rotatably supported by the protrusion and the supporting hole, and are prevented from coming off by the engaging piece, a separate rotating shaft can be omitted, and crimping work on the supporting part can be simplified. This also eliminates the need for this process, reducing process costs.
