When generated by the rotation of the rollers to cause the emission SOLVED light emitting unit, there is a problem in the rotation of the roller is in the heavy load, and it provides only a sluggish massage feeling. emission [SOLUTION] section is connected rotatably with respect to the handle 10 about an axis of rotation ax along the length direction the roller 30 of the rod-like body is polygonal, to provide the side 31B of the roller 30, 31D, the 31F The light is emitted by the built-in battery provided in the handle 10 or 30 roller section 32B-1~3,32D-1~3,32F-1~3. Iontophoresis is also possible if energized this mounting iontophoresis electrode on the side of the roller. [Selection Figure Figure 2【課題】発光部を発光させるのにローラの回転で発電すると、その負荷でローラの回転が重くなり、鈍重なマッサージ感しか得られないという課題があった。【解決手段】断面が多角形で棒状体のローラ30をその長さ方向に沿う回転軸axを中心にハンドル10に対し回転自在に連結し、このローラ30の側面31B,31D,31Fに設ける発光部32B-1~3,32D-1~3,32F-1~3をローラ30またはハンドル10に備える内蔵電池により発光させる。ローラの側面にイオン導入電極を取付けこれに通電すればイオン導入も可能である。【選択図】図2
