Abstract:
Extending/contracting flexible pipe that has weather resistance, a structure in which a tie rod can properly exhibit its function, and easy assembly. The pipe including: a pair of joint sections (1) configured to be oscillatable and extendable/contractile with respect to each other; an attachment section (10) formed at the outer periphery of each of the pair of joint sections; a tie rod (5) inserted into rod holes (11) formed at the attachment sections and bridged across both of the attachment sections; and a washer (6) and nut (7) for fixing the tie rod to the attachment sections. An annular spacer (8) made of an elastic member is fixed to the tie rod. The washer is located at a position at which the rod hole is closed in the state in which the spacer is disposed inside of the rod hole, so that the washer shields the spacer from the outside.
