PROBLEM TO BE SOLVED: To provide a switching valve structure which can reduce manufacturing cost. SOLUTION: The switching valve structure includes: a first exhaust pipe (41) having an enlarged part (411); a second exhaust pipe (42) and third exhaust pipe (43) formed with flat parts (422, 432) on a part of end parts, and having insertion parts (421, 431); and a valve (50) supported by a rotary shaft (51) provided on the enlarged part (411) and restricting a flow of exhaust gas to the second exhaust pipe (42) or the third exhaust pipe (43). In a state that the flat part (422) of the second exhaust pipe and the flat part (432) of the third exhaust pipe face to each other, the insertion part (421) of the second exhaust pipe and the insertion part (431) of the third exhaust pipe are inserted in the enlarged part (411). An end part of the flat part (431) of the third exhaust pipe is extended to the first exhaust pipe (41) side than an end part of the flat part (421) of the second exhaust pipe.
