The locking pin is formed opposite to the locking recess to form a lock pin :::: The impact protrusion is applied tightly. • The large output moves in a direction away from the locking recess. Therefore, the locking pin cannot move with the locking protrusion-away from the locking recess, and cannot follow the cam. Since the groove moves in a direction away from the locking recess, the card can be prevented from flying out due to an impact with a simple structure. In addition, since the lock pin is at the lock position held by the heart-shaped cam groove, the lock projection is pushed toward the lock by the lock projection of the guide member that is urged by the spring for applying spring force. Recess. This can prevent the locking pin from loosening in the locked state, so that the card insertion state can be stabilized. In addition, since the locking pin restricts the movement of the lock pin in the return direction in the heart-shaped cam groove by the locking projection, it is not necessary to provide a step portion in the heart-shaped cam groove to restrict the return of the lock pin from the locking recess. Therefore, the thickness of the heart-shaped cam groove portion can be reduced, and the casing can be reduced in thickness. In addition, since the i-th inclined surface and the second inclined surface are formed on the locking protrusion, the former is inclined in the direction of the locking pin similarly to the moving direction of the locking pin; the latter is opposite to the direction of the locking pin. The direction of the lock was released. · At -22-, the standard for Chinese paper (CNS) A4 (210 X 297 mm) applies to this paper. 586257 5. Description of the invention
