PROBLEM TO BE SOLVED: To provide a jacket in which a heat transfer sheet can be prevented from being 'displaced', 'folded', 'wrinkled' and 'broken' by fitting the heat transfer sheet to a predetermined position of the jacket by simple work.SOLUTION: In a cooling jacket 60, sheet holding grooves 610 are a pair of grooves that holds both ends of one heat transfer sheet 79. A first regulating surface 611 and a third regulating surface 613, inner surfaces of the pair of grooves, regulate movement of the heat transfer sheet 79 in a thickness direction, which can prevent the heat transfer sheet 79 from 'floating' and 'warping up' in the thickness direction. As a result, 'displacement', folding, wrinkle and breakage of the heat transfer sheet 79, with which it is impossible to cope just by arranging the heat transfer sheet 79 on a supporting part 61, can be eliminated, so that the jacket can secure necessary heat transfer performance eventually. |
