PROBLEM TO BE SOLVED: To allow a rotation speed sensor to be attached to and detached from an engine without removing the engine from a vehicle body frame and allow the perimeter of the rotation speed sensor to be protected while restraining the number of components from increasing.SOLUTION: A step bar 40 including footrest parts for a driver is detachably provided on the undersurface of an engine case 18, and a rotation speed sensor 50 is attached in proximity to the attaching position of the step bar 40 on the undersurface of the engine case 18 so as to be directed toward a rotating body while being partially covered by the step bar 40. |
