First Claim
Patent Images
1. An exhaust system for exhaust gas discharged from an engine, the exhaust system comprising:
- an exhaust pipe including an inner pipe arranged to guide the exhaust gas and an outer pipe mounted outside of the inner pipe;
whereina first through-hole is provided in a peripheral surface of the outer pipe to receive an insert member inserted from outside the outer pipe into the inner pipe;
a second through-hole is provided in a peripheral surface of the inner pipe to receive the insert member;
third through-holes are provided in the peripheral surface of the outer pipe at a different position than that of the first through-hole; and
when the exhaust system member is connected to the exhaust pipe, the third through-holes are arranged at a position inside of the exhaust system member.

Abstract
An exhaust system includes an exhaust pipe. The exhaust pipe includes an outer pipe and an inner pipe. A first through-hole and a second through-hole are provided in a peripheral surface of the outer pipe and a peripheral surface of the inner pipe, respectively, to receive an exhaust gas detector. Third through-holes are provided in the peripheral surface of the outer pipe, at a different position than that of the first through-hole. Since the third through-holes are provided in the outer pipe, a liquid can be drained promptly from a space between the outer pipe and inner pipe. Exhaust gas can be prevented from being discharged to the atmosphere by sealing the third through-holes.
