ANGLE ADJUSTING DEVICE

摘要

A rigid angle adjusting device, wherein a ratchet gear is installed on a pair of arms (rotating bodies) connected to each other through a bolt at the opposed surfaces of a pair of rotating parts which are opposed to each other axially with the bolt used as a relative rotating axis, each rachet gear comprises a plurality of gear teeth, and both arms are energized by a spring in the directions opposed to each other, whereby the relative rotating position of the arms can be adjusted stepwise at an angle corresponding to the gear teeth so as to avoid a size from increasing and form the device at a low cost.
