PROBLEM TO BE SOLVED: To provide a structure that makes a cooler in a housing less likely to be damaged during a collision in a connection structure where an outer refrigerant pipe and an inner refrigerant pipe are connected at a housing wall of an on-vehicle device.SOLUTION: In a connection structure 10, a tube 23 in a housing and an outer refrigerant pipe 40 at the exterior of the housing are connected at a housing wall 14. A joint pipe 30 fits in a through hole 16 provided at the housing wall 14. The tube 23 fits in the joint pipe 30 from the inner side of the housing, and the outer refrigerant pipe 40 fits in the joint pipe 30 from the outer side of the housing. A space Sp is secured between a tip of the tube 23 and a tip of the outer refrigerant pipe 40 in the joint pipe 30. A flange 42a is provided at an outer periphery of the outer refrigerant pipe 40, and the flange 42a contacts with a flange 31 of the joint pipe 30. |
