PROBLEM TO BE SOLVED: To provide a vibrator for body exercise which is excellent in durability.SOLUTION: In a vibrator for body exercise, shaft means (13) provided on both sides in a width direction in the center of a vibration member (2) is pivotally supported by supporting mechanisms (4) raised on both sides in a width direction of a seat member (1), and the vibration member is vertically vibrated about the shaft means by a vertical driving mechanism (5) and is laterally vibrated with the shaft means by a lateral driving mechanism (6). The supporting mechanism (4) is configured by rotatably holding a peripheral circumferential part (17a) of a rotor (17) along a circumference using a central axis (18) as a center by an inner circumferential part (16a) of a supporting body (16), and connecting the shaft means (13) to a site above the central axis (18) of the rotor (17). A strength part (Q) is formed by a joining part between the peripheral circumferential part (17a) along an arc located below the circumference using the central axis (18) as the center and the inner circumferential part (16a).SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】耐久性に優れた身体運動用振動機を提供する。【解決手段】座部材(1)の幅方向両側に立設した支持機構(4)に振動部材(2)の中央の幅方向両側に設けた軸手段(13)を軸支し、振動部材を上下駆動機構(5)により軸手段の廻りで上下振動させ、左右駆動機構(6)により軸手段と共に左右振動させる身体運動用振動機において、前記支持機構(4)は、それぞれ中心軸(18)を中心とする円周に沿うロータ(17)の外周部(17a)を支持体(16)の内周部(16a)により回転自在に保持し、ロータ(17)の中心軸(18)よりも上方の部位に軸手段(13)を連結することにより構成され、中心軸(18)を中心とする円周のうち下側に位置する円弧に沿う外周部(17a)と内周部(16a)の接合部分により耐力部(Q)が形成されている。【選択図】図４
