ABSTRACT:
A positioning device intended for use in a housing of a car sideview mirror to turn the housing to a viewing position where the driver is allowed to have a rear view, a front parking position where the rear side of the housing is generally parallel with the car body and to a rear parking position where the mirror side of the housing is generally parallel with the car body, has a stationary member to be coupled to a base of the sideview mirror and a rotary member to be coupled to the housing. The stationary member has a pair of arcuate grooves formed therein and the rotary member has also a pair of arcuate grooves therein correspondingly to those in the stationary member. The corresponding arcuate grooves in the stationary and rotary members define together regions, respectively, in each of which a ball is retained so as to roll. Also a stopping mechanism is provided between the rotary and stationary members to limit the turning of the housing to a predetermined range. The rotary member is rotatable through an angle corresponding to the arcuate groove in the stationary member as well as an angle corresponding to the arcuate groove in the rotary member, so the positioning device can be commonly used in sideview mirrors different from each other in the angle from the viewing position to the rear parking position as well as in the angle from the viewing position to the front parking position. Furthermore, a same positioning device can be used commonly in a driver sideview mirror for a right-steered car and a passenger sideview mirror for left-steered car. Therefore, it is not necessary to provide many different types of the positioning devices for use in car sideview mirrors.
