　図１２から図１５に示すように、蓋体２の端部に形成されたヒンジ孔４ａに、トップカバー１に形成されたヒンジ軸５が挿入される。蓋体２のヒンジ部４に突出部４４が形成され、突出部４４に形成された取付け孔４ｂに蝶番バネ３の一端の係止部３ａが係止される。蝶番バネ３の他端の係止部３ｂは、トップカバー１に形成された係止孔７ａに係止される。また、トップカバー１には、ヒンジ部４が差し込まれる差込孔６が形成され、蝶番バネ３を支持するための凹部７が差込孔６に連続して形成されている。 12 to 15, the hinge shaft 5 formed on the top cover 1 is inserted into the hinge hole 4a formed on the end of the lid 2. A protruding portion 44 is formed on the hinge portion 4 of the lid body 2, and the locking portion 3 a at one end of the hinge spring 3 is locked in the mounting hole 4 b formed in the protruding portion 44. The locking portion 3 b at the other end of the hinge spring 3 is locked in a locking hole 7 a formed in the top cover 1. Further, the top cover 1 is formed with an insertion hole 6 into which the hinge portion 4 is inserted, and a recess 7 for supporting the hinge spring 3 is formed continuously with the insertion hole 6.
　しかしながら、このような従来の構成では、蓋体２のヒンジ部４には、蝶番バネ３を係止するための取付け孔４ｂが形成されるための突出部４４が必要なため、蓋体２の開閉軌跡上でヒンジ部４の突出部４４がトップカバー１と干渉しないように、トップカバー１には、大きく開口した差込孔６が設けられている。 However, in such a conventional configuration, the hinge portion 4 of the lid body 2 requires the protruding portion 44 for forming the attachment hole 4b for locking the hinge spring 3. The top cover 1 is provided with a large opening 6 so that the protrusion 44 of the hinge portion 4 does not interfere with the top cover 1 on the opening / closing locus.
　差込孔６には、異物が侵入する場合があり、異物の侵入により蓋体が開ききらない等の動作不具合が生じるおそれがある。また、蓋体をトップカバーに組み立てるときには、蝶番バネ３を自由長の状態から取付け可能な状態まで撓ませながら、トップカバー１の係止孔７ａおよび蓋体２の取付け孔４ｂに取り付けられる必要があるため、不安定な作業となり、作業性が悪い。さらに、トップカバー１と蓋体２とが擦れて傷が付かないように配慮する必要があるため、組立作業性が良くない。また、蓋体２が開放された際に、ヒンジ部４が露出し、蓋体２裏面のリブおよびヒンジ軸５等が露出するためデザイン性が悪い。また、ヒンジ部４は、複雑な形状であるため、汚れを拭き取りにくく、掃除時の利便性が悪い。 異物 Foreign objects may enter the insertion hole 6, which may cause malfunctions such as the lid not fully opening due to the intrusion of foreign objects. Further, when the lid is assembled to the top cover, it is necessary to attach the hinge spring 3 to the locking hole 7a of the top cover 1 and the mounting hole 4b of the lid 2 while bending the hinge spring 3 from the free length state to the attachable state. Therefore, the work becomes unstable and workability is poor. Furthermore, since it is necessary to consider that the top cover 1 and the lid 2 are not rubbed and scratched, the assembling workability is not good. In addition, when the lid 2 is opened, the hinge portion 4 is exposed, and the rib on the back surface of the lid 2 and the hinge shaft 5 are exposed, so that the design is poor. Moreover, since the hinge part 4 is a complicated shape, it is hard to wipe off dirt and the convenience at the time of cleaning is bad.
