造。 A first exhaust pipe connected to a manifold of an automobile engine; a second exhaust pipe connected to an end of the first exhaust pipe via a spherical pipe joint or a bellows pipe for relative angular movement; In an exhaust pipe structure consisting of a tail pipe that is connected to the end of the exhaust pipe and discharges exhaust gas into the atmosphere, one end of the second exhaust pipe is connected to the spherical pipe joint or the bellows pipe, and the other end of the second exhaust pipe is connected to the spherical pipe joint or the bellows pipe. A flange having a partially concave spherical surface on the inner surface is fixed to the outer peripheral surface of the pipe, leaving the end of the tail pipe, and a flange with a partially concave spherical surface on the inner surface is fixed to the end of the tail pipe, which is disposed opposite to the other end of the second exhaust pipe. A flange having a partially concave spherical surface part is fixed to the second exhaust pipe with the concave spherical part facing the partially concave spherical part of the flange, and an insertion hole is provided on the inner surface of the outer peripheral surface of the pipe end of the second exhaust pipe. , a sealing member having partially convex spherical surfaces on both side surfaces maintains an annular gap between the insertion hole and the outer circumferential surface of the tube end, and has partially convex spherical sections on the partially concave spherical surface of the flange, respectively. The flange fixed to the second exhaust pipe and the flange fixed to the tail pipe are arranged in sliding contact with each other, and the flange fixed to the second exhaust pipe and the flange fixed to the tail pipe are a pair of headed bolts with one end clamping and fixing the other flange. An exhaust pipe structure for an automobile, characterized in that the head part and the other flange are connected by a pair of coil springs for relative angular movement.
