摘要:
Provided is a tubular structure that, even when clearance between a housing and the tubular structure is large, can prevent tube removal and that is capable of absorbing a certain amount of vibration in a lengthwise direction and a manufacturing method therefor. The present invention is a tubular structure 100 comprising a tube member 1 provided with annular protrusions 12, 22 on a side of an insertion opening 11 that is a tube end part or a receiving opening 21 and, on the outer circumference of the ring member 1, ring members 13A, 13B arranged on an opposite side of the tube end part with respect to the annular protrusions 12, 22 having two side surfaces that are vertical with respect to an axis A of the tube member 1.
