Document Type and Number:
Japanese Patent JP2020083611
Kind Code:

Abstract:
To provide a lock mechanism which can exhibit a target lock force and also can secure reliability of lock release.SOLUTION: A lock mechanism that locks movement of a device movable along a guide part includes: a contact member 202 which is movable between a contact position and a separation position with respect to the guide part; and an elastic body 230 which imparts a contact force to the contact member 202 at the contact position. The lock mechanism further has support mechanisms 209 and 214 which support the contact member 202 so as to be movable between the contact position and the separation position, and operation mechanisms 223, 221 and 231 which move the contact member 202 to the contact position via the elastic body 230. Furthermore, the lock mechanism also has regulation means which regulates movement of an end opposite to the contact member side of the elastic body 230 against the elastic force of the elastic body, when the contact member 202 is in the contact position.SELECTED DRAWING: Figure 10
