PROBLEM TO BE SOLVED: To provide a cylindrical massage tool that enables a pubis periphery to be subsidiarily stimulated when male genitalia are stimulated in piston motion, and thereby can promote blood circulation in a lower body and recovery of a male function.SOLUTION: A cylindrical massage tool includes slits 7 that are cut deep from a bottom, bottom grooves 5, a cavity 9 in the side wall and a projection 4 in an upper lid part 3, in a cylindrical elastic material with an inner cavity penetrated through. The cavity of the sidewall of the massage tool is crushed, so that the massage tool pressure force caused by the piston motion for stimulating male genitalia is not transmitted to the bottom with a recess, and the cavity of the sidewall is restored from the crushed state when the piston motion for stimulating the male genitalia is separated, and thereby the entire massage tool made of the elastic material is vibrated.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】男性器をピストン運動で刺激する際、副次的に恥骨周辺を刺激可能にして下半身の血行促進及び男性機能の回復を促すことのできる筒型マッサージ具を提供する。【解決手段】中の空洞が貫通した筒状の弾性素材において、底部から切込んだスリット7と底部溝5と側壁に空洞9と上蓋部3に突起物4を備えている。本マッサージ具の側壁の空洞を潰すことで、男性器を刺激するピストン運動による本マッサージ具を圧迫する力を窪みのある底にまで伝えず、男性器を刺激するピストン運動が離れる際に側壁の空洞が潰れた状態から元に戻ることにより弾性素材でできた本マッサージ具全体を振動させる。【選択図】図5
