Abstract:
1. A push-push latch device provided between a movable body and a main body, comprising: a cam member adapted to be attached to one of the movable body and the main body, and a pin member adapted to be attached to the other of the movable body and the main body for coupling and decoupling with the cam member, said pin member having a coupling position with said cam member and a decoupling position with the cam member according to a movement of the movable body relative to the main body, wherein said cam member includes a base, and a divided body rotationally supported on the base and having a locking part for coupling with the pin member so that when said divided body receives a load above a predetermined value through said pin member in the coupling position, the divided body moves to release forcible coupling of said pin member with the cam member to absorb the load, and wherein said cam member further includes a movement restricting device for moving said divided body from a normal position when receiving said load above the predetermined value, an impelling device for urging the divided body moved from the normal position to return again to the normal position after releasing the coupling with the pin member, a support hole provided on the base, a shaft part projecting from a bottom face of the divided body and passing through the support hole, and a linkage plate fixed on a leading end side of the shaft part so as to rotate along with the shaft part, said impelling device being disposed between a bottom face of said base and the linkage plate for impelling the divided body toward the base to absorb play in an axial direction of the shaft part and enabling said divided body to return again to said normal position after releasing the coupling with said pin member.
