Therefore, a sufficient frictional resistance between the belt and each bar can be obtained without reducing the distance between the first bar and the second bar. Therefore, the belt mounting portion of the present invention, it is possible to perform the insertion of the belt easily, the frictional resistance between the belt and each bar can be sufficiently obtained. In addition, since sufficient frictional resistance between the belt and each bar can be obtained, it is not necessary to form an uneven shape or a sawtooth shape on each bar, and a simple configuration can be obtained, which facilitates manufacture.

  • the second bar has a cross-sectional shape that expands in a direction toward the first bar.
  • the second bar is formed in a shape in which the cross-sectional shape expands in the direction toward the first bar, so that the belt to which the tension is applied swells greatly toward the first bar due to the restoring force. For this reason, in the state where tension is applied, the distance between the first bar and the second bar becomes pseudo smaller than the actual distance. Therefore, in the present invention, when the belt is inserted between the first bar and the second bar, the belt can be inserted in a wide interval dimension. If tension is applied after the insertion, the interval dimension is actually simulated. Thus, the frictional resistance between the belt and each bar can be sufficiently ensured.
