To provide a lock mechanism for reducing a low-grade sound in locking by reducing the number of part items.
Since an elastic piece 52 can be elastically deformed, an elastic locking claw 60 is arranged in the elastic piece 52, and a slit 56 is formed around the elastic locking piece 60, and elastic force can be doubly used by elastic force by the elastic piece 52 and elastic force by the elastic locking claw 60 by elastically deforming the locking claw locked on a locking hole 26. When the slit 56 is not formed around the elastic locking claw 60, a deflection quantity of the elastic piece 52 required for locking on the locking hole 26 becomes δ1, and a deflection quantity of the elastic piece 52 and the elastic locking claw 60 can be respectively set to δ2 and δ3 (δ2 < δ1, and δ3 < δ1) by using the elastic force of the elastic piece 52 and the elastic locking claw 60. That is, since the deflection quantity of the elastic locking claw 60 can be reduced in spite of being the same in locking force, the low-grade sound generated when locking the elastic locking claw 60 on the locking hole 26 can be reduced.
