<p>A locking apparatus locks a moving body to a housing against an urging force applied to the moving body. The locking apparatus includes a cam provided on one of the moving body and the housing, and having an engagement groove and a releasing groove, and a swivel body provided on the other of the moving body and the housing. The swivel body has a trace pin moving along the grooves and a balancer for balancing the trace pin. Thus, upon receiving a sudden load when the trace pin is in an engaging condition with the engagement groove, the trace pin is prevented from moving from the engagement groove to the releasing groove to thereby lock the moving body.</p> |
