Plural slat plates 2 are arranged continuously in the longitudinal direction between a pair of right and left endless chains 1, 1, and the right and left ends of the respective slat plates 2 are installed to the endless chains 1, 1. The longitudinal length of the slat plate 2 is made to almost conform to the center distance of bends of adjacent chains of the endless chain 1. At least either one of the but ends of each of the slat plates 2, 2 is formed into acute angle in a sectional view. The but position of the slat plates 2, 2 is allowed to coincide with the position of the center of bend of the endless chain.
