To easily change an angular range, within which a lock is maintained in a released state, in an angle adjustment device.MEANS FOR SOLVING THE PROBLEM: An angle adjustment device 14 has: a first rotor 41 coupled to a first component 18; a second rotor 42 which is rotatably supported on the first rotor, and is coupled to a second component 21; a lock member 43 which is movable between a lock position and a release position; an energization component 44 which energizes the lock member toward the lock position; an operation part 45 which is so provided on the second rotor as to be displaceable between an initial position and an operation position, and moves from the initial position to the operation position, thereby moving the lock member to the release position against energization force of the energization component; and a first contact part 71 which is provided on the first component or the second component, and contacts the operation part to maintain the operation part at the operation position when an angle of the second component with respect to the first component falls within a prescribed first angular range.SELECTED DRAWING: Figure 8

    【課題】角度調節装置において、ロックが解除された状態に維持される角度範囲の変更を容易にする。【課題を解決するための手段】角度調節装置14は、第1部材18に結合される第1回転体41と、第1回転体に回転可能に支持されると共に、第2部材21に結合される第2回転体42と、ロック位置と解除位置との間で移動可能なロック部材43と、ロック部材をロック位置に向けて付勢する付勢部材44と、初期位置と操作位置との間で変位可能に第2回転体に設けられ、初期位置から操作位置に移動することによって、付勢部材の付勢力に抗してロック部材を解除位置に移動させる操作部45と、第1部材又は第2部材に設けられ、第1部材に対する第2部材の角度が所定の第1角度範囲にあるときに操作部に当接して操作部を操作位置に維持する第1当接部71とを有する。【選択図】図8
