PROBLEM TO BE SOLVED: To provide a cooling unit whose heat insulation case is easily detached even if the division face of the case is not on the same plane. SOLUTION: This cooling unit has a styrol heat insulation case 1 provided with the first styrol-molded case 2 with long jetty-shaped protrusions 5, 7, the second styrol-molded case 3 with recesses 6, 8 in which the protrusions 5, 7 fit and an elastic body 9 pasted between the protrusions 5, 7 and the recesses 6, 8. By this, the unit is easily divided even if the case 1 is constituted to be divided with the division face continuing in a planar direction and an elevation direction as a boundary. Also by the elastic body, sealing performance when fitted is secured. COPYRIGHT: (C)2009,JPO&INPIT
