To improve working efficiency when mounting two temperature sensors for detecting a refrigerant leakage in an evaporator.
In an inlet side pipe 15 and an outlet side pipe 16 of an evaporator mutually juxtaposed in parallel, a first holding body 21 for fitting an inlet temperature sensor 20 in an inlet side pipe 15 and a first holding body 22 for fitting an outlet temperature sensor 20 in an outlet side pipe 16 are provided, and both the holding bodies 21, 22 are unified. Each of holding bodies 21, 22 comprises a mounting cylindrical part 23 inserted in the pipe 15, 16 and a holding cylindrical part 24 communicating therewith and in which the temperature sensor 20 is inserted. The mounting cylindrical parts 23 of the holding bodies 21, 22 are connected together through a connection arm 25.
