Abstract

PURPOSE:To reverse a garbage container held in lashed state by interlocking the motion thereof with the expanding and contracting motion of a lift cylinder, without any need of fitting an actuator for the operation of a lashing means to secure the container to a holding seat. CONSTITUTION:A clamp member 52 turns upward as well, together with a joint member 53, due to the expansion of a lift cylinder 6, thereby clamping the upper end section A1 of a garbage container A. When the lift cylinder 6 is further expanded, a holding seat 4 turns upward and the container A is lifted upward with the member 52 and a holding piece 51. As a result of this turning motion, a stopper 55 is inserted in and coupled to the insertion hole of the holding seat 4, due to the energizing force of a spring. Also, the clamp member 52 firmly holds the upper end section A1 of the container A in cooperation with the holding piece 51, as a result of the insertion and coupling of the stopper 55 to the insertion hole, thereby prohibiting a turning motion in a clamp releasing direction. When the lift cylinder 6 is further expanded from that state, the seat 4 is reversed and garbage therein is delivered to a garbage discharge box 1 via a discharge opening 11.
