PURPOSE:To decrease line pressure by providing a pressure contact transfer block unit part which engages with a transferbelt-shaped substance in the front and in the rear of a truck and shifting the transfer block together with the transferbelt-shaped substance when shifting the truck and operating the assisting mechanism of the truck at the time of accumulating so as to separate the transfer block from the transferbelt-shaped substance. CONSTITUTION:A pressure contact transfer block unit part 4 is provided in the front and rear ends of a truck 3 and a transfer block 6 in the unit part 4 is made to contact with a transferbelt-shaped substance 5 at all times. When a group of trucks 3 contact with a stopper 17 and stops, unit parts 4, 4 of the trucks 3, 3 in front and in rear which confront each other are made to pressure contacted with each other. Then the assisting mechanism 7 of the unit parts 4, 4 is operated by the pressure contact force. And, the transfer blocks 6, 6 are separated from the transferbelt-shaped substance 5. As a result, line pressure applied to the stopper 17 for stopping a group of trucks 3, 3 is decreased.
