A balancer shaft includes a shaft body, a driven gear, a fixed member fixed to the shaft body, and an elastic member located between the driven gear and the fixed body. A projection projects from the driven gear. The fixed member includes an accommodation recess accommodating the projection. The elastic member is arranged in the accommodation recess adjacent to the projection. The projection includes an abutment side surface, which includes an outer end. The outer end and the elastic member are spaced apart in the circumferential direction by a first distance when the abutment side surface and the elastic member are in abutment without elastically deforming the elastic member. The first distance is greater than a maximum value of an elastic deformation amount of the elastic member in the circumferential direction when the elastic member is pressed between the projection and a wall of the accommodation recess.
