Patent abstract
A split type connecting rod has a simple structure that is capable of suppressing rotation of a metal bearing, and avoiding problems such as burning. The split type connecting rod 200 holds a crank-pin through a metal bearing 213 which has locking lugs 213c, 213d. A bearing locking groove 201h locks at least one of the locking lugs 213d when the metal bearing 213 rotates forward in the circumferential direction of a crank-pin hole 101d. A bearing locking groove 201i locks at least one of the locking lugs 213c when the metal bearing 213 rotates backward. The bearing locking grooves 201h, 201i are deviated from each other in the circumferential direction.
