PROBLEM TO BE SOLVED: To provide a locking mechanism that prevents the rattling of locking parts each other with a pair of locking parts in a locked state, and that prevents damage to locking claws when a force acts in the direction of releasing the lock. SOLUTION: A locking part 22 has the locking claw 23 and fitting grooves 24 arranged to face each other at both sides of the locking claw 23. Another locking part 32 has the other locking claw 33 and fitting frame parts 34 arranged to face each other at both sides of the locking claw 33. The fitting grooves 24 are inserted into the fitting frame parts 34 to engage the fitting claw 23 with the fitting claw 33. In this fitting structure, the inside surfaces of the fitting frame parts 34 incline in such a way that the cross sectional area of an inserting space decreases toward the inserting direction, and the fitting grooves 24 incline in such a way that the cross sectional area of the fitting stripes decreases toward the inserting direction. The fitting grooves 24 are fitted to the fitting frame parts 34 with each surface in contact. COPYRIGHT: (C)2003,JPO
