<P>PROBLEM TO BE SOLVED: To provide a connecting structure capable of enhancing assemblability while securing connection strength, and fittings. <P>SOLUTION: When a load acts in the direction of separation of outdoor and indoor members 11A and 11B connected to each other, a crossing portion 35 turned inside an engaging recess 24 is protruded so that an engaging protrusion 32 can be prevented from coming off the engaging recess 24. Since an extended portion 34 of the engaging protrusion 32 and a bent portion 36 thereof resist the load by a tensile force, the connecting strength can become higher than that of such a connecting structure as to maintain engagement by bending rigidity thereof. Thus, a sufficient connecting strength can be acquired even when a cross section of the engaging protrusion 32 is not expanded. Then, when the outdoor and indoor members 11A and 11B are assembled, a force for inserting the engaging protrusion 32 into the engaging recess 24, while elastically deforming the engaging protrusion 32, can be decreased for an improvement in the assemblability. <P>COPYRIGHT: (C)2011,JPO&INPIT |
