REFRIGERATOR

PURPOSE: To perform a positive fixing of a frosting prevention pipe and an inner box flange by a method wherein there is provided a pushing member for pushing a root portion of the inner box flange in a rearward direction of an outer box flange into a forming groove. CONSTITUTION: A main body 1 of a refrigerator is comprised of an outer box 2, an inner box 3 and a foamed thermal insulating material 4 and the like, a holding groove 2c is formed by a bent-back section 2b formed at a rear side of the outer box flange 2a and by a rear surface of the outer box flange 2a. The inner box flange 3a formed at a circumferential edge of the inner box 3 has a concave groove 3b, and a concave groove 3b of the inner flange receiving a frosting prevention pipe 7 is resiliently contacted to the outer box flange 2a by the bent-back portion 2b. A pushing member 5 arranged at the holding groove 2c pushes the inner box flange 3a against the rear surface of the outer box flange so as to prevent a clearance from being generated at a section A' during a foaming operation. In accordance with this arrangement, the frosting prevention pipe can be fixed without using any fitting member, no clearance arises in between the outer box and the inner box flange and then the contact of the frosting prevention pipe with outer box flange as well as their workability can be improved.
