To provide a rotary member angle adjustment mechanism which includes an operation part, enables stepless adjustment, and thereby enables improvement of operability.SOLUTION: A rotary member 4 angle adjustment mechanism M which is provided so as to rotate vertically relative to a seat frame has: a shaft 5 serving as a rotary shaft; a lock spring 6 which brings rotation of the rotary member 4 into a lock state by force which winds and tightens the shaft 5; and a lock release part 7 which releases the lock state. The lock release part 7 includes: an operation part 70 which is provided at a part of the rotary member 4 and operated by an operator; an engagement part 71 which engages with an operation side end part 6b of the lock spring 6 and can move in a direction such that the engagement part 71 relaxes the force which winds and tightens the shaft 5; and a connection part 72 which connects the operation part 70 with the engagement part 71 and moves the engagement part 71 in the direction such that the engagement part 71 relaxes the force, which winds and tightens the shaft 5 and is applied by a coil part 6a, in conjunction with operation of the operation part 70.SELECTED DRAWING: Figure 3

    【課題】操作部を備えるとともに無段階調整を可能とし、これによって操作性の向上を図ることができる回転部材の角度調整機構を提供することを目的とする。【解決手段】シートフレームに対して上下に回転可能に設けられた回転部材4の角度調整機構Mが、回転軸となるシャフト5と、シャフト5を巻き締める力で回転部材4の回転をロック状態とするロックスプリング6と、ロック状態を解除するロック解除部7と、を備える。ロック解除部7は、回転部材4の一部に設けられ、操作者によって操作される操作部70と、ロックスプリング6の操作側端部6bに係合し、シャフト5を巻き締める力を緩める方向に移動可能とされた係合部71と、操作部70と係合部71とを連結し、操作部70の操作に伴って、係合部71を、コイル部6aによるシャフト5を巻き締める力を緩める方向に移動させる連結部72と、を有する。【選択図】図3
