CARRYING CHAIN

Japanese Patent JP3535130

B2

PROBLEM TO BE SOLVED: To provide a carrying chain with links having a bearing part and a pair of leg parts connected to each other in an endless manner by a connection pin in which a space between the leg parts is prevented from being narrowed when the connection pin is inserted in the leg part of the links to connect the links, and degradation of bending performance and defective bend of the carrying chain caused by the compressed and narrowed bearing part can be prevented.
SOLUTION: In the carrying chain 11, the links 12 having the bearing part 14 and a pair of leg parts are connected to each other in an endless manner by the connection pin 19. A tip of the connection pin is inserted in and fitted to a pin hole 17a so as to abut on a receiving projection part 17c formed in the pin hole 17a of the leg part 17, and the other end of this connection pin is inserted in and fitted to a pin hole 16a of the other leg part 16 so that a locking projection part 19a formed in the connection pin abuts on an edge of the pin hole 16a. Since the locking projection part 19a abuts on the edge of the pin hole 16a, the inward inclination of the leg part 16 is prevented, and the space between the leg parts is prevented from being narrowed.
