To provide a lock mechanism having excellent operability.SOLUTION: A lock mechanism 1 comprises: a rotor 2 that rotates between an engagement input position and a release input position; a knob 4 having a pressing part disposed outwardly in a radial direction relative to a knob turning shaft 4A, which rotates between a normal position and a release operation position; an engaging part having a pair of rods respectively connected to one and the other of a pair of rod connection parts, which changes a state between an engaged state and a released state accompanying a rotation of the rotor 2; a rotor energization member that energizes the rotor 2 to the engagement input position; and a knob energization member that energizes the knob 4 to the normal position. During an opening operation in which the knob 4 rotates from the normal position to the release operation position, the pressing part of the knob 4 slides on a receiving face R of the rotor 2 and presses the receiving face R to make the rotor 2 rotate from the engagement input position to the release input position, where (A)≥0.8×(B). (A) is a length of projecting a slide trajectory of the pressing part of the receiving face R on an axially perpendicular cross section of the rotor 2, and (B) is a length of an actual change in position of the pressing part.SELECTED DRAWING: Figure 3
【課題】動作性に優れたロック機構を提供する。【解決手段】係止入力位置と解除入力位置との間を回動するロータ2と、ノブ回動軸4Aに対して径方向外側にある押圧部と、通常位置と解除操作位置との間を回動するノブ4と、一対のロッド接続部の一方および他方に各々に接続される一対のロッドを有し、ロータ2の回動に伴って係止状態と解除状態との間を状態変化する係止部、ロータ2を係止入力位置に付勢するロータ付勢部材と、ノブ4を通常位置に付勢するノブ付勢部材と、を具備し、ノブ4が通常位置から解除操作位置まで回動する開操作時に、ノブ4の押圧部がロータ2の受圧面R上を摺動しつつ受圧面Rを押圧して、ロータ2を係止入力位置から解除入力位置に回動させ、(A)≧0.8×(B)である、ロック機構1。(A)受圧面Rにおける押圧部の摺動軌跡を、ロータ2の軸直方向断面上に投影した長さ、(B)押圧部が実際に位置変化した長さ。【選択図】図3
