Summary:PROBLEM TO BE SOLVED: To suppress the abrasion of a D-cut part provided in a gear shaft with a bearing hole. SOLUTION: The D-cut part 25 of an idler gear shaft 21 is formed such that its left side which is the forward side of the rotating direction of the crank gear 5 on the first engagement point P1, becomes smaller than the right side which is the opposite side of the rotating direction, with respect to a line L4 parallel to a line L2 connecting a first engagement point P1 where an idler gear 7 engages with a crank gear 5 and a second engagement point P2 where the idler gear 7 engages with a balancer gear 6, and passing the shaft center C1 of the idler gear shaft 21.
