An overhead valve engine has rocker arm pivoted portions (13),(13) oriented substantially in a right and left direction and arranged side by side in a front and rear direction. Each of rocker arm output portions (15),(15) projects from one end portion of each of the rocker arm pivoted portions (13),(13) in a direction opposite to a space between the pivoted portions (13),(13). Each of rocker arm input portions (16),(16) projects from the other end portion of each of the pivoted portions (13),(13) toward the space between the pivoted portions (13),(13). The respective rocker arm input portions (16),(16) are arranged side by side between the rocker arm pivoted portions (13),(13) in the right and left direction.
