To provide a telescopic apparatus which is helically wound to reduce stress generated in two belts forming a pipe structure. A telescopic apparatus according to an embodiment of the present disclosure includes: a telescopic pipe structure formed by helically winding a first belt and a second belt about an axis, the second belt being arranged inside the first belt; a first belt case for housing a part of the first belt which does not form the pipe structure in a spiral form; and a second belt case for housing a part of the second belt which does not form the pipe structure in a spiral form. The first belt case and the second belt case are integrally formed as one component, and the thickness of the first belt is thinner than that of the second belt.
