Vehicle optical radar apparatus
摘要:
In this vehicle optical radar apparatus, the number of parts constituting an oscillating mechanism can be reduced, assembling facilities can be improved, an accumulated error of the parts can be decreased, and light weight and low cost can be obtained. An oscillating member (29) consists of a resin-molded product constituted by a light-sending mirror holding portion (33), a light-receiving mirror holding portion (34), and a cylindrical member. A shaft (30) fitted with the cylindrical member of the oscillating member (29) and a rotating shaft (22a) of a pulse motor are pivotally supported by a housing (24) and a cover which are the case of the pulse motor and consist of a resin-molded product. A follower (36) is rotatably attached to a follower attachment plate (35) attached to the light-receiving mirror holding portion (34). The follower (36) is stored in an eccentric cam groove (26a) of the cam (26) fixed to the rotating shaft (22a). Therefore, a light-sending mirror (14) and the light-receiving mirror (15) are synchronously oscillated about the shaft (30) as serving as an oscillation center.
