The present embodiment is as described above, and the basic operation in which the chain 6 driven by the driving device 8 is guided by the chain guide 3 and rotationally moved is not substantially different from that of the prior art. However, in the present embodiment, the chain 6 is attached to the return guide portion 3B of the chain guide 3.
Is provided, and a paddle sliding contact body 9 is provided on the starting end 5A side of the missing portion 5. The operation of the missing portion 5 and the paddle sliding contact 9 will now be described with reference to FIG. The excrement and the like transferred by being attached to the paddle 7, particularly the litter transported in a state of being entangled with the paddle 7 (A in the figure), are fixed to the paddle sliding contact body 9 which is the fixed side and the moving side. It is in a state of being sandwiched between a certain paddle 7 (B in the figure). When only the paddle sliding member 9 is further moved, the litter entangled with the paddle 7 is pulled in a direction in which the paddle 7 is released from the paddle 7 (C in the figure), and the paddle 7 is separated from the paddle sliding member 9. At this point, most of the litter falls from the paddle 7 downward.

The paddle sliding contact 9 is provided with its axis B and the slant oblique to the direction of movement of the chain 6, and the paddle 7 passes through the upper side surface 9 A of the paddle sliding contact 9.
The paddle slides from the base end side of the paddle sliding contact body 9 toward the distal end. Therefore, when removing the litter from the paddle 7, the litter attached to the paddle sliding body 9 is removed from the subsequent paddle 7.
