Abstract:
An angle adjusting device capable of adjusting a relative rotating position of a pair of rotors coupled through an axis of rotation step by step, comprising:a pair of rotors; a plurality of engaging portions provided on opposing surfaces of the pair of rotors opposing in a direction along the axis of rotation; a spring for pushing the pair of rotors in an opposing direction; a releasing body placed concentrically between the pair of rotors, wherein the releasing body allows engagement between the pair of rotors when placed at a first rotating position with respect to either one of the pair of rotors, and releases the engagement by moving the pair of rotors apart from each other when placed at a second rotating position wherein: the releasing body is provided with two contact portions spaced apart in a direction of a relative rotation with respect to the other rotor; and the other rotor is provided with a moving portion that moves between the two contact portions in association with a relative rotation with respect to the releasing body, the moving portion allowing the releasing body to rotate to the first and second rotating positions with respect to the either one of the rotors by touching the two contact portions, respectively.
