PROBLEM TO BE SOLVED: To reduce a vertical or horizontal bulking, maintain the stability of a spring, suppress a bulking of a bending portion in a compressed state and prevent a goods pusher from falling and getting lost. SOLUTION: In the goods pusher 1 wherein a restoring and pushing force from a proximal end B to a distal end A is imparted in a longitudinally compressed state, by using a zigzag plate spring 2 made by linking plate portions 3 in a zigzag state when seen from the side, in the zigzag plate spring 2, a through hole 4 is nearly spiral along the longitudinal central axis X and the center of which is continuous along the longitudinal central axis X, reinforcing portions 17 of the shape nearly following the bending of the bent portions 5 are interposed and integrally connected in the vicinity of the zigzag bent portion 5 of the zigzag plate spring 2.
