Abstract
The metal conductive plate 60 electrically connecting the bracket 51 on the output side and the bracket 52 on the counter-output side includes: a first abutting portion 61 formed on one end and abutted on a side of the bearing house 520 on the counter-output side, the first abutting portion 61 warping in a direction away from the case 20; a second abutting portion 62 formed on the other end and abutted on an inner side of the bracket 51 on the output side press-fitted on the case 20; and a conductive sleeve 63 connecting the first abutting portion 61 and the second abutting portion 62. The conductive plate 60 and the case 20 include a holding unit for holding a state in which the first abutting portion 61 is abutted on the side of the bearing house 520 on the counter-output side.
