- the dimensions of the holding component 42 itself, the mounting portions 21 s and 21 t, the circuit board 31, the board housing portion 21 d, and the like are set so that the holding component 42 does not come into contact.
- the board holding component 42 can be arbitrarily set in the direction of the axis L 1 (board insertion direction). Can be mounted at the position. Therefore, similarly to the above-described embodiment, even if a dimensional error occurs in the direction in which the circuit board 31 and the cover member 13 approach or separate from each other, the sealing performance of the cover member 13 and the circuit board are ensured. 3 It is possible to prevent rattling.
- the board holding component 42 grips substantially the center of the circuit board 31 in the left-right direction in FIG. 6 (the flat direction of the gear housing 21).
- circuit board 31 is reliably held by the holding portion 42c by the elastic force of the holding portion 42c. Therefore, it is possible to prevent rattling not only in the insertion direction of the circuit board 31 but also in a direction orthogonal to the plane direction of the circuit board 31.
- the shape of the board holding components 41 and 42 may be appropriately changed.
- the configuration of the mounting portion for mounting them is changed according to the shape change.
- the positions where the board holding components 41 and 42 are arranged may be changed.
- two or more substrate holding parts 41 and 42 may be used.
- the board holding parts 41 and 42 may be mounted on the gear housing 21 with screws.
- FIGS. 8 and 9 may be used. That is, as shown in FIG. 8, a hemispherical projection 21 V is formed on the upper and lower surfaces of the communication hole 21 h of the connector case 21 g ′, and the projection 21 V is formed on the connector body 33. Provide a recess 33a that engages with Also, as shown in FIG. 9, a projection 21 w having a triangular cross section is formed on the lower surface of the communication hole 21 h of the connector case 21 g and the projection 21 w engages with the connector body 33. A four part 3 3b is provided. By doing so, the connector body 3 3 (circuit board 3 1) engages with the connector case 21 g (gear housing 21), so that the rattling of the circuit board 31 is reduced. It can be reliably prevented.
- each component of the motor 1 such as the motor unit 2, the reduction unit 3, and the circuit board 31 is not limited to this, and may be changed as appropriate.
- the present invention is applied to the motor 1 used as a drive source of the vehicle power window device, but may be applied to a motor used in other devices.
