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.
