PROBLEM TO BE SOLVED: To prevent worsening in appearance of a medical apparatus caused by a hinge which supports a closing member in an openable and closeable manner.SOLUTION: A first metal plate 32B of a hinge 32 is arranged inside rather than a peripheral edge 291 of a lid member 29, and the first metal plate 32B is fixed onto a box shape member 40 inside rather than the peripheral edge 291. Thereby, the hinge 32 becomes not to bridge the lid member 29 and an upper plate 43 of the box shape member 40, and thus worsening in appearance is suppressed. When the hinge 32 is arranged so as to bridge the lid member 29 and the upper plate 43, a case where a rotational axis part of the hinge 32 is arranged in a gap part formed between the lid member 29 and the upper plate 43 is increased. In this case, the gap is expanded, and the worsening in appearance may be caused along with the expansion of the gap.COPYRIGHT: (C)2015,JPO&INPIT【課題】塞ぎ部材を開閉可能に支持するヒンジに起因する医療用機器の見栄えの悪化を生じにくくする。【解決手段】蓋部材29の外周縁291よりも内側に、ヒンジ32の第1金属板32Bが配置されており、且つ、外周縁291よりも内側にて、第1金属板32Bが箱状部材40に対して固定されている。これにより、ヒンジ32が、蓋部材29と箱状部材40の上板43とを跨がないようになり、見栄えの悪化が抑制される。蓋部材29と上板43とを跨ぐようにヒンジ32が設けられる場合、ヒンジ32の回転軸の部分が、蓋部材29と上板43との間に形成される間隙の部分に配置されることが多くなる。ところで、この場合、この間隙が拡がり、間隙の拡大に伴い、見栄えの悪化が生じうる。【選択図】図10
