Abstract
The need for an O ring cover is eliminated when a gap between a shaft portion of a mover for mirror surface angle detection and a hole in a sensor case is sealed using an O ring. An O ring that allows a shaft portion of a slide block to be inserted therethrough is interposed between a sensor case and an actuator housing. The sensor case and the actuator housing are interconnected by means of screw-fastening via screws, and the O ring is brought into pressure contact with and held between the sensor case and the actuator housing by means of the screw fastening forces.
Claims9
A vehicle mirror apparatus comprising:
- a tilting device tilting a mirror to adjust a tilting angle of the mirror;
- and a mirror surface angle detection device detecting the tilting angle of the mirror,
- the tilting device including a base member, a tilting member supporting the mirror on a front side of the base member so as to be tiltable around a predetermined tilting center, and a drive device exerting a driving force between the base member and the tilting member to tilt the tilting member,
- the mirror surface angle detection device including a sensor case, a mover and a position detection device,
- the sensor case being attached to a back side of the base member,
- the mover including a rear end portion, a front end portion and a shaft portion between the rear end portion and the front end portion, the rear end portion being housed in the sensor case, the shaft portion being inserted through a hole formed in the sensor case, the front end portion projecting to an outside of the sensor case,
- the mover being arranged so as to be movable relative to the sensor case in an axial direction of the shaft portion, the front end portion projecting to the outside of the sensor case penetrating a hole formed in the base member and engaging with the tilting member, the mover moving in the axial direction of the shaft portion, following tilting of the tilting member,
- the position detection device being housed in the sensor case and detecting a position in an axial direction of the mover relative to the sensor case,
- the vehicle mirror apparatus further comprising a seal structure sealing a gap between the shaft portion of the mover and the hole in the sensor case,
- the seal structure including a ring-shaped seal member interposed between the sensor case and the base member with the shaft portion of the mover, the shaft portion projecting from the sensor case, passed through a center hole of the seal member, and a screw member screw-fastening the sensor case and the base member together to interconnect the sensor case and the base member, and bringing the seal member into pressure contact and holding the seal member between the sensor case and the base member via a force of the screw fastening.
