The front bottom of a chain returning portion(A5) is higher than the bottom thereof in order to form the stepped portion. The extended portion is formed to be horizontally extended from the front of the chain returning portion to the direct rear end of the stepped portion. A front screen(A4) is horizontally formed into the horizontal front screen on the upper end of the stepped portion. The water current guiding plate is formed at the front of the horizontal front screen, and covers the horizontal front screen.
