PROBLEM TO BE SOLVED: To provide a coupler, coupling structure and coupling method for a receiver capable of accurately, smoothly and exactly coping with the expansion or contraction of the receiver though having a simple structure without the need for forming a through hole at the receiver.;SOLUTION: The coupling structure for the receiver comprises: two receivers; the first and second couplers 11, 12 individually fixed to the two receivers; and a coupling member 20 for coupling the couplers 11, 12. The coupling member 20 relatively slidably couples the two couplers 11, 12 associated with the expansion or contraction of the two couplers 11, 12 fixed to the two receivers. An abutting means 50 that abuts to the sidewall external face of the other receiver is provided so as to allow the slide to one coupler in a state that the sidewall of one receiver to which the one coupler is fixed and the sidewall of the other receiver to which the other coupler is fixed are consistently arranged.;COPYRIGHT: (C)2003,JPO
