To reduce the transmission of vibrations from a body frame to a rotary switch, thereby preventing any trouble in the rotary switch and reliably maintaining the function and performance of the rotary switch. A side stand device includes a side stand bracket mounted on the body frame. A side stand is rotatably mounted through a pivot shaft to the bracket, and a rotary switch is provided in coaxial relationship with the pivot bolt through a securing bolt. A sheet is interposed between the rotary switch and the pivot bolt, and a tube and a sheet are interposed between the rotary switch and the securing bolt. The sheets and the tube are formed from rubber members. A cushion member is interposed between an engaging member of an inner rotor in the rotary switch and a locking hole of the side stand. The cushion member is formed from a rubber member.

Compactness is enhanced while retaining the performance, noise deadening characteristic and engine output. The ratio of the distance, a, from a gas outlet end, p, of an exhaust pipe to an inner wall of a rear partition wall to an inside diameter &empty;A of the exhaust pipe is set in a relation of 0.6&lE;(a/&empty;A)<1.2, while the ratio of the distance, b, from a gas inlet end, q, of a tail pipe to an inner wall of a front partition wall to an inside diameter &empty;B of the tail pipe is set in a relation of 0.4&lE;(b/&empty;B)<1.2, to afford a silencer having an optimum combination of engine output characteristic and compactness while retaining a noise deadening effect.
