<p>PURPOSE: To eliminate the possibility of the occurrence of an accidental push release operation by a simple constitution excellent in general-purpose properties. CONSTITUTION: The locking device comprises a push-push locking mechanism, which is composed of a cam part 20 with a heart-shaped cam groove 22, which is provided in one of a moving body and a housing, and a slewing boy 30 which is provided in the other of them and has a trace pin 35 moving along the cam groove 22. The push-push locking mechanism makes the moving body locked to a fixed position of the housing by a push operation against urging force of an urging means and enables this locking to be released by the next push operation. The slewing body 30 has a balancer 33 (36, 37, etc.), capable of inhibiting the trace pin 35 from moving from an engaging groove 22b of the cam groove 22 to the side of an guide cam groove 22c for release by detecting an accidental load such as an impact when put under the load in a state of the above locking.</p> |
