PROBLEM TO BE SOLVED: To attach/detach a heater core to/from a unit case without damaging a packing on a side surface of the heater core and further to hold the inserted heater core so as not to drop it from the unit case. ! SOLUTION: A distal end portion 70a5 (another end portion) of a claw 70a of which one end portion 70a1 is fixed around an opening 58 of a unit case 10 is temporarily held by a protrusion 10a (lock part) so as to be engaged/disengaged. After a heater core 60 is inserted into the opening 58 of the unit case 10, the distal end portion 70a5 of the temporarily held claw 70a is detached, and the distal end portion 70a5 is locked in a groove 68 which is provided at an edge of a rar surface of the heater core 60 in the direction of insertion. The distal end portion 70a5 of the claw 70a locked in the groove 68 is detached and temporarily held by the protrusion 10a (lock part) and the heater core 60 is removed from the opening 58 of the unit case 10. !
