With respect to [problem] development training can be performed such massaging devices of sense, such as the vaginal muscle or train the pelvic floor muscles, or given a different stimulus and vibration stimulation, inserted into the vagina has been made to ensure without is that extruded, such as the attitude of a state in which inserted may persist stably provides a novel massaging device. An upper side of the seat surface 11, the back waist addressed 12, approximately in the center opening 13 which is open to, projected on this front has been pre-destined 2 of the seat surface, than the opening 13 electric motor housed in a chair 1 which is composed of the reciprocating member 3 for projecting, a crank and a connecting rod attached to a rotating plate which is provided on the shaft of the electric motor, actuating lever of vertical installation is connected to the connecting rod , the reciprocating member 3 is a member that is inserted into the vagina in operation lever is detachably attached, and as the rotational motion of the electric motor is converted into reciprocating motion of the reciprocating member 3.FIELD 1【課題】骨盤床筋群を鍛えたり膣筋などの感覚の開発訓練が行えるようなマッサージ具に関して、振動刺激とは異なる刺激を与えたり、膣への挿着が確実に行われて押し出されることがなく、挿着した状態の姿勢を安定的に持続し得るような、新規なマッサージ具を提供する。【解決手段】上側の座面11、後側の腰宛て12、座面のほぼ中心部に開口された開口部13、この前方に突設された前宛て2、開口部13より突出する往復部材3とから構成された椅子1に電動モータが収められ、電動モータのシャフトに設けた回転盤にクランクとコネクティングロッドとが取り付けられ、コネクティングロッドには垂直設置の作動桿が連結され、作動桿に膣に挿着される部材である往復部材3が着脱自在に取り付けられて、電動モータの回転運動が往復部材3の往復運動に変換されるようにした。【選択図】図1
