れコスト的にきわめて有利なものである。The brush terminal 10 is inserted into the brush holder portion 5a, and the protruding portion 10a is inserted into the mounting hole 1e of the board 1. In this state, the mounting screws 14 and 15 are tightened to attach the board 1 to the motor frame 5. The mounting screw 14 is screwed into the mounting boss 5b through the mounting hole 13d of the holding plate 13, and the mounting screw 15 is screwed into the mounting boss 5c through the mounting holes 13e and lb. In this case, the guide hole lf of the substrate 1
A protrusion 5e penetrates through. And the presser plate 13 has a protrusion 5
d, 58 and the notches 13a, 13b, and at the same time, the bearing metal 9 is held by the receiving part 13c, and the bearing metal 9 and the conductive part around the mounting hole lb of the board 1 are electrically connected, and the ground is connected. It has the effect of In this way, the present invention earths the capacitor board via the holding plate attached to the motor frame, so there is no need for a grounding lead wire or a grounding terminal board, which reduces the number of parts and simplifies assembly. This makes it extremely advantageous in terms of cost.
