Claims

[Scope of utility model registration request]

a base unit having a shaft that rotates back and forth and attached to the bottom of a loading platform; an arm unit that has one end attached to the shaft and rotates vertically together with the shaft; and the arm unit. a gate unit portion rotatably attached to the other end side and rotatably movable between a storage position attached to the rear surface of the loading platform and a use position substantially parallel to the floor surface of the loading platform; A gate opening/closing lock structure for a tailgate lifter, comprising a releasable engagement lock portion for rotationally locking a gate unit portion to a locked pawl member of the loading platform in the storage position, wherein the engagement lock portion is a rod rotatably attached to the gate unit; one end fixed to the rod, a locking claw provided at the other end, the other end protruding from the gate unit at a substantially right angle; and the locked claw member. a locking pawl member that locks the locking pawl, a spring that applies a biasing force in a direction in which the locking pawl member protrudes from the gate unit portion, and a spring that is interlocked with the rotational movement of the gate unit portion. As it rotates toward the use position, the locking claw member is rotated and retracted into the gate unit portion against the biasing force of the spring, and when it rotates toward the storage position, it is automatically moved to the lock position. A gate opening/closing lock structure for a tailgate lifter characterized by having a means for returning the gate.
