To provide a lock mechanism with excellent operability.SOLUTION: The lock mechanism comprises: a base having a notch into which an engaged member can be inserted; a latch member having a hook and a first receiving face, rotatably connected to the base around a first rotation axis; and a lock member having a lever and a restriction part, rotatably connected to the base around a second rotation axis. The latch member can be rotated between an engaging position in which a portion of the notch is blocked by the hook and the engaged member inserted into the notch is surrounded with a wall surface of the notch and the hook, and an engaging release position in which blocking of the notch by the hook is released. The lock member can be rotated between a lock position in which the restriction part is brought into contact with the first receiving face of the latch member in the engaging position and the rotation of the latch member towards the engaging release position is restricted, and a lock release position in which the first receiving face of the latch member in the engaging position and the restriction part are separated. When the lock member is rotated from the lock position towards the lock release position, the restriction part does not interfere with the latch member.SELECTED DRAWING: Figure 5

    【課題】 操作性に優れたロック機構を提供する。【解決手段】 一実施形態に係るロック機構は、被係合部材を挿入可能なノッチを有するベースと、フックおよび第1受け面を有しベースに対し第1回転軸を中心として回動可能に連結されたラッチ部材と、レバーおよび規制部を有しベースに対し第2回転軸を中心として回動可能に連結されたロック部材とを備える。ラッチ部材は、フックによりノッチの一部が閉塞され、ノッチに挿入された被係合部材がノッチの壁面とフックとで囲われる係合位置と、フックによるノッチの閉塞が解除される係合解除位置との間で回動可能である。ロック部材は、係合位置にあるラッチ部材の第1受け面に規制部が当接し係合解除位置に向けたラッチ部材の回動が規制されるロック位置と、係合位置にあるラッチ部材の第1受け面と規制部が離間したロック解除位置との間で回動可能である。ロック位置からロック解除位置に向けてロック部材を回転させる際に、規制部がラッチ部材と干渉しない。【選択図】 図5
