Claims

[Claims for Utility Model Registration] 1. A rack-type sprocket fixed to a fixed fork, a sprocket rotatably attached to an intermediate fork that is telescopically supported by the fixed fork, and a sprocket that is telescopically supported by the intermediate fork. Rack-type sprockets fixed to the tip fork are arranged in the same row and have a chain meshed with each of the sprockets, and a rack-type sprocket is fixed to the intermediate fork. and a fork device in which a chain for driving the rack type sprocket is provided on the fixed fork side. 2. The transfer device according to claim 1, wherein the sprocket has two rows of teeth so that the teeth of the sprocket do not come into contact with the teeth of the rack type sprocket. 3. The transfer device according to claim 1, wherein the sprocket is a toothless idle roller so that the teeth of the sprocket do not come into contact with the teeth of the rack type sprocket.
