PROBLEM TO BE SOLVED: To provide a muscle electrostimulator capable of inhibiting it from floating from a part to be mounted.SOLUTION: A muscle electrostimulator comprises a body part 20 having a mounting surface 10b to be mounted along the girth of a bodys part to be mounted. The mounting surface 10b extends in X direction in which the part to be mounted is enclosed. On the body part 20 are provided: front face electrode parts disposed apart from each other to supply current through the part to be mounted and a pair of belt coupling parts 42 disposed apart from each other in the X direction, the belt coupling parts being used for coupling a belt member 50, a hauling member for hauling the body part to the side of the part to be mounted. The belt member 50 extends in the X direction on the side opposite to that of the body part 20 of the part to be mounted and is stretched over between the pair of belt coupling parts 42.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】被装着部からの浮き上がりを抑制することが可能な筋肉電気刺激装置を提供する。【解決手段】身体の被装着部の周囲に沿って装着される装着面10bを有する本体部20を備える。装着面10bは、被装着部を周回するX方向に延在し、本体部20には、互いに離間して配置され、被装着部に電流を流すための正面電極部と、X方向に離間して配置され、本体部を被装着部側に引寄せるための引寄部材であるベルト部材50を連結する一対のベルト連結部42と、が設けられ、ベルト部材50は、被装着部の本体部20とは反対側をX方向に延びて、一対のベルト連結部42の間に架け渡されている。【選択図】図1
