To provide a lock mechanism that prevents lock from being released by external force to improve anti-theft performance and improves design flexibility of a solenoid and peripheral components.SOLUTION: A lock mechanism includes: an operation mechanism (50); a first restriction unit (71) configured to move to a restriction position in which an operation of the operation mechanism (50) is restricted and an allowable position in which the operation of the operation mechanism (50) is allowed; and a solenoid (73) configured to operate the first restriction unit (71). A second restriction unit (72) which is movable separately from the first restriction unit (71) in a movement direction of the first restriction unit (71). When the first restriction unit (71) moves to the allowable position, the second restriction unit (72) can be moved to a second restriction position in which the operation of the operation mechanism (50) is restricted by the second restriction unit (72).SELECTED DRAWING: Figure 8

    【課題】ロック機構において、外力によってロックが解除されることを抑制して防盗性を向上させるとともに、ソレノイド及び周辺部品等について設計の自由度を向上する。【解決手段】ロック機構は、動作機構(50)と、動作機構(50)の動作を規制する規制位置及び動作機構(50)の動作を許容する許容位置に移動する第1規制体(71)と、第1規制体(71)を動作させるソレノイド(73)とを備え、第1規制体(71)の移動方向において第1規制体(71)とは別に移動可能な第2規制体(72)が設けられ、第2規制体(72)は、第1規制体(71)が許容位置に移動する際に、第2規制体(72)によって動作機構(50)の動作を規制する第2規制位置に移動可能である。【選択図】図8
