Abstract
A vehicular exhaust pipe structure includes an outer pipe extending along a front-rear direction of a vehicle and an inner pipe disposed inside the outer pipe along an axial direction of the outer pipe. The inner pipe is joined to the outer pipe such that a vacuum layer is formed between the inner pipe and the outer pipe. The inner pipe includes a pseudo-cylindrical concave polyhedral shell-shaped part.
