Rotation plate and motor

摘要

A rotation plate including a surface, in which a fixed contact terminal slides in contact with the surface of the rotation plate. The rotation plate includes a movable contact plate and a holding member. The movable contact plate forms a predetermined conductive pattern. The holding member holds the movable contact plate and is formed from an insulating resin material. The movable contact plate and the holding member are molded integrally and fixed to each other so that a surface of the movable contact plate is exposed and does not project outward from a surface of the holding member.

主权项

1. A motor comprising:
a motor unit that generates rotation; a deceleration mechanism that decelerates the rotation, wherein the deceleration mechanism includes an output shaft, which is coupled to a wiper, and a worm wheel, which rotates integrally with the output shaft; a rotation plate that is rotatable together with the worm wheel, the rotation plate including: a movable contact plate that forms a predetermined conductive pattern; and a holding member that holds the movable contact plate, wherein the holding member is formed from an insulating resin material; and a plurality of fixed contact terminals that slide in contact with a surface of the rotation plate and the movable contact plate to detect a rotational position of the output shaft with the rotation plate, wherein the motor unit is supplied with power in accordance with the rotational position of the output shaft detected with the rotation plate and the fixed contact terminals, and wherein the movable contact plate and the holding member are molded integrally and fixed to each other so that a surface of the movable contact plate is exposed and does not project outward from a surface of the holding member.
