PROBLEM TO BE SOLVED: To provide a massage mechanism capable of performing effective tapping operation.SOLUTION: This massage mechanism includes: a motor 14 a pair of rubbing shafts 17 and 17 arranged so that the direction crossing the treatment surface of a part to be treated thereof is set as an axial direction and having the eccentric shaft part 36 eccentrically rotated on the basis of the rotation of the motor 14 a tapping shaft 19 rotated on the basis of the rotation of the motor 14 a link member 20 for connecting the rubbing shafts 17 and 17 and the tapping shaft 19 and a massage member 11 for massaging the part to be treated. The massage member 11 performs not only rubbing operation so as to follow the eccentric rotation of the eccentric shaft part 36 but also the operation of the link member 20 so as to follow the rotation of the tapping shaft 19 to alternately advance and retreat the pair of the rubbing shafts 17 and 17 along the axial direction thereof to perform tapping operation.COPYRIGHT: (C)2013,JPO&INPIT【課題】効果的な叩き動作を行うことができるマッサージ機構を提供する。【解決手段】モータ14と、被施療部の施療面と交差する方向を軸方向として配置され、モータ14の回転に基づいて偏心回転する偏心軸部36を有する対の揉み軸17,17と、モータ14の回転に基づいて回転する叩き軸19と、揉み軸17と叩き軸19を連結するリンク部材20と、被施療部をマッサージするマッサージ部材11と、を有している。マッサージ部材11は、偏心軸部36の偏心回転に追従して揉み動作を行うとともに、叩き軸19の回転に追従してリンク部材20が動作することにより、対の揉み軸17,17が揉み軸17の軸方向に沿って交互に進退して叩き動作を行う。【選択図】 図2
