PURPOSE: To decrease the number of component parts and improve a sealing characteristic between the component parts by a method wherein a cooling air discharging duct and an extremity end of a lid of evaporator are extended until they are abutted against the inner-most part of a circumferential groove of the discharging port of a dressed cover.
CONSTITUTION: A dew receiver pan and a casing 25 having a lower half part of a mouth ring and a lower half part of a casing integrally formed with a synthetic resin are mounted on a case 22. A casing 26 having the upper half part of the mouth ring and the upper half part of the casing integrally formed with a synthetic resin is assembled with an evaporator lid. Then, a casing 27 integrally formed with a synthetic resin is mounted on the casing 26 so as to cover the inner surface of the cabinet 21 from the upper part of the casing. Extremity ends of the evaporator lids of the casing 27 and the casing 26 are extended until they are abutted against the inner-most part of the circumferential groove at the discharging port of the dreesed cover 30. In this way, the casings 25, 26 and 27 are formed by synthetic resin and complex shapes are made, thereby it is made possible to improve the sealing characteristic of the assembled component parts.
