PROBLEM TO BE SOLVED: To provide a structure in a hook attachment part capable of reducing molding cost.SOLUTION: A back case 31 constituting a casing 3 is formed in a container shape, and so configured as to be molded with a first mold 42 forming an inside surface 41 and a second mold 44 forming an outside surface 43. An inwardly receding recessed part 101 is arranged on the outside surface 43 of the back case 31. Insertion holes 121, 122 into which extending parts 15, 16 on a hook main body 11 are respectively inserted are formed on corner parts of an inner wall surface 111 constituting the recessed part 101 and a second step part 103. A part of the first mold 42 and a part of the second mold 44 which form the inner wall surface 111 and the second step part 103 are so configured as to partially contact on their surfaces at portions respectively forming the insertion holes 121, 122. Each of the insertion holes 121, 122 is formed in a manner where unformed portions of the inner wall surface 111 and the second step part 103 are formed on the inner wall surface 111 and the second step part 103.COPYRIGHT: (C)2015,JPO&INPIT【課題】成型コストを抑えることができるフック取付部構造を提供する。【解決手段】ケーシング3を構成する裏ケース31を容器状に形成し、裏ケース31を内側面41を形成する第一金型42と外側面43を形成する第二金型44とで成型可能に構成する。裏ケース31の外側面43に内側に後退した凹部101を設け、凹部101を構成する奥壁面111と第二段部103との角部に、フック本体11の各延出部15,16を挿入する挿入穴121,122を形成する。奥壁面111及び第二段部103を形成する第一金型42の部位と第二金型44の部位とは、各挿入穴121,122を形成する部分において、部分的に面接するように構成し、奥壁面111及び第二段部103に、奥壁面111及び第二段部103が未形成の部分を形成することで、各挿入穴121,122を形成する。【選択図】図3
