<P>PROBLEM TO BE SOLVED: To provide a case coupling mechanism capable of both improving impact resistance while a case is coupled and allowing easy separating operation of the coupled case. <P>SOLUTION: In conjunction with the operation that an auxiliary hook member 10 enters a case 1, claws 21a and 21b of a hook member 20 move to an engagement position and a first spring body 23 elastically displaces so that its tip part 25 is hooked with a spring body hooking part 12d formed at the tip part on the other end side of the auxiliary hook member 10, coming into such state as abutted with a tip tapered part 60a of first guide bodies 6a and 6b. Meanwhile, in conjunction with such operation of the auxiliary hook member 10 that has entered the case 1 as recedes, the hooking state between the tip part 25 of the first spring body 23 and the spring body hooking part 12d of the auxiliary hook member 10 as well as the abutting state between the tip part 25 of the first spring body 23 and the tip tapered part 60a of the first guide bodies 6a and 6b are released, thereby the claws 21a and 21b of the hook member 20 moving to a releasing position. <P>COPYRIGHT: (C)2009,JPO&INPIT |
