PROBLEM TO BE SOLVED: To provide an exercise auxiliary device having high convenience.SOLUTION: An exercise auxiliary device 1 can deform among plural forms containing a first form in which a top surface of a seat part 10 is substantially flat, and a second form in which a part of a top surface of the seat part 10 protrudes. The exercise auxiliary device 1 reduces oscillation speed of the seat part 10 when the form is changed from the second form to the first form, or when the form is changed from the first form to the second form in a state of oscillating the seat part 10, and when deformation of the seat part 10 is completed, restores the oscillation speed of the seat part 10 to original oscillation speed before deformation.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】利便性が高い運動補助装置を提供する。【解決手段】運動補助装置1は、座部10の上面が略平坦な第1の形態と、座部10の上面の一部が突出する第2の形態とを含む複数の形態に変形可能であり、運動補助装置1は、座部10を揺動させた状態で、第2の形態から第1の形態に変形する際、或いは、第1の形態から第2の形態に変形する際に、座部10の揺動速度を落とし、座部10の変形が完了すると、座部10を変形前の元の揺動速度に戻すものである。【選択図】図3
