Abstract
A push-push type latch device includes a cam member and a pin member provided respectively on a movable body and a main body for coupling and decoupling with the cam member. The latch device locks the movable body in a first position on the main body via a coupling of the pin member and the cam member, and releases the coupling by pushing from the first position and releasing a pushing force to switch to a second position. The cam member includes a divided body including a locking part for coupling with the pin member. When the divided body receives a load above a predetermined value through the pin member in a state when coupled with the pin member, the divided body rotates to release the coupling with the pin member with accompanying movement toward a direction to absorb the load.
