<p>PROBLEM TO BE SOLVED: To provide a training apparatus, despite weight saving, preventing bending deformation in use by providing it with excellent support strength.SOLUTION: A body 1 of a training apparatus T comprises a first support part 2, and a second support part 3 branched from a length-directional halfway portion of the first support part 2. Pedals 11 are rotatably fitted to the branch portion of the second support part 3 in the body 1. A section from an installation end S1 of the first support part 2 to an installation end S2 of the second support part 3 has an arch shape formed by a curved face formed by continuation of the lower face of the body 1. When the pedals 11 are stepped, component force in the direction of depressing is acted on a rotary shaft 12. Stress produced in the body by the depressing force can be substantially uniformly distributed in a range from the installation end S1 of the first support part 2 to the installation end S2 of the second support part 3, so as to effectively suppress deformation of the training apparatus T.</p> |
