<p>A lock mechanism (10) for a mobile body is provided with a lock device (50) having a cam groove (80), a pin (a pin section (92), for example), and a rotating plate (90). The lock device (50) is provided with a biasing means (a plate spring (110), for example) for applying rotational resistance to the rotating plate (90) by axially biasing the axial center of the rotating plate (90) is installed between the rotating plate (90) and either a base (a housing (20), for example) or the mobile body (a holder body (30), for example). With the lock mechanism (10), erroneous operation of the lock device (50) due to a reduction in friction, which reduction is caused by thermal creep, is prevented by axially biasing the axial center of the rotating plate (90) having either the cam groove (80) or the pin which traces the cam groove.</p> |
