With respect to male sexual dysfunction sufferer-use assistance devices, various examples of prior art describe requiring a penis to become erect and so forth, but this is close to impossible. Therefore, as a means for fitting a device and achieving the intended goal without having an erection, inevitably a hard sheath-like object that simulates an erect penis must be used. A structure should be designed in which the drawbacks of a sheath-like object are eliminated. Further, with respect to shape, material, and function, the device must be able to be worn, and inserted, without causing any discomfort to the user or a female partner. Provided is an assistance device comprising a hard sheath that simulates an erect penis and that has on the end thereof an air-bleed hole, and a soft skin that covers the entire hard sheath and that has an air-bleed hole at a position that is slightly offset from the air-bleed hole of the hard sheath, and the device has added thereto a valve function due to the two air-bleed holes. The assistance device utilizes to the upmost the state of the penis and the theory of negative pressure application, and can be worn and inserted with discomfort reduced to a great degree.【課題】勃起しなくとも装着でき、形状・素材及び機能において使用者及び相手女性側共に違和感なく受け入れられる男性性不全者用補助器具を提供する。【解決手段】勃起した陰茎を模した硬質サック1とし、内側には女性の膣内部に似た感触、基部には陰茎の挿入を容易にしつつ空気の流入を阻止する軟質ゴム状の材質を一体成型した二層構造とし、先端に空気抜き孔2を配する。また、硬質サック全体を被覆する軟質スキンの先端に上記硬質サック1の空気抜き孔2からややずらした位置に空気抜き孔を配することによってバルブ機能を付加する。【選択図】図3
