WIPO Patent Application WO/2023/176804
Kind Code:
A1
Abstract:
[Problem] To allow the distance between and resistance of handles to be suitably set in a plurality of stages. [Solution] A training tool 30 in which a first annular part 11 and a second annular part 12 are linked by a linking part 13 is configured such that when a user uses the training tool 30, the force needed to expand the tool in a longitudinal direction is different between when the first annular part 11 is grasped and expanded so as to achieve a reference length W1 and when the second annular part 12 is grasped and expanded so as to achieve the reference length W1, and the force needed to expand the tool in a transverse direction intersecting the longitudinal direction, when the first annular part 11 is grasped and expanded so as to achieve the reference length W1 and when the second annular part 12 is grasped and expanded so as to achieve the reference length W1, is different from the force needed to expand the tool in the longitudinal direction.
