Abstract
An exhaust pipe assembly of two-passage and double-pipe construction has an inner pipe; a partition plate meeting the inner pipe at both diametrical meeting ends thereof so as to be elongated in a longitudinal direction of the inner pipe. Two passages divided across a diameter of said inner pipe are thus formed. The assembly also has an outer pipe which covers the inner pipe with a thermally insulating space around a periphery of the inner pipe. The outer pipe has on one longitudinal end thereof a connecting portion for connection with a mating member. One end of the inner pipe is fixedly connected to the outer pipe with a clearance between the periphery of the inner pipe near each of the meeting ends and an inner circumference of the outer pipe.
