PROBLEM TO BE SOLVED: To provide a novel training device with a simple configuration, adjusting an interval between two operation parts by synchronously moving the two operation parts.SOLUTION: The training device includes: a base 34D on which a load acts; first and second rotation shafts 432A and 432B; first and second arms 34B that are fixed to the first and second rotation shafts at one ends respectively, and connected to first and second operation parts at the other ends; first and second movable bodies 434A and 434B fixed to the first and second rotation shafts respectively; and a synchronization mechanism provided to the first and second movable bodies and synchronously rotating the first and second movable bodies in the mutually opposite directions by a substantially same rotation angle with the first and second rotation shafts used as fulcrums. Any one of the first and second operation parts connected to a fulcrum shaft is rotatingly operated, with any one of the first and second rotation shaft defined as the fulcrum shaft to move the first and second operation parts axisymmetrically with respect to a center line L that halves an interval between the first and second operation shafts, and to adjust an interval W between the first and second operation parts.SELECTED DRAWING: Figure 22 |
