PROBLEM TO BE SOLVED: To allow a handle to be attached to and detached from a cooler box and prevents the handle from coming off.SOLUTION: The mounting structure includes a mounting plate 21, a projecting part 52, and a coming-off prevention member. The mounting plate 21 is provided at a predetermined interval from the left side face of a cooler box body and has a mounting hole. The projecting part 52 is formed at the front end of the handle 50 and inserted into a mounting hole. The coming-off prevention member has a first lock part 61 lockable to the lower end of the mounting plate 21, a plate part 62 which regulates the movement of the handle 50 by locking to the projecting part 52 in a state of being displaced between the left side face and the mounting plate 21, and an urging part 63 which urges the plate part 62 to the mounting plate 21 side in such a way that the plate part 62 inserted between the left side face and the mounting plate 21 approaches the mounting plate 21 side.COPYRIGHT: (C)2009,JPO&INPIT【課題】ハンドルをクーラーボックスに着脱可能にするとともに、外れるのを防止すること。【解決手段】取り付け板部21と、突出部52と、抜け防止部材とを備えている。取り付け板部21は、クーラーボックス本体の左側面から所定の間隔に設けられ、取り付け用孔を有する。突出部52は、ハンドル50の先端に設けられ、取り付け用孔に挿入可能である。抜け防止部材は、取り付け板部21の下端に係止可能な第1係止部61と、左側面と取り付け板部21との間に配置された状態において突出部52に係止することでハンドル50の移動を規制する板状部62と、左側面と取り付け板部21との間に挿入された板状部62が取り付け板部21側に近接するように板状部62を取り付け板部21側に付勢する付勢部63とを有する。【選択図】図2
