Abstract
PURPOSE: To set the spring characteristic of a torsion spring according to its use and operating condition via the selection of the member and size of an elastic member and a reinforcing member by fitting the cylindrical torsion spring made of the elastic member reinforced with the reinforcing member to the rocking shaft of a swing arm. CONSTITUTION: When a rear wheel 3 is thrust up by the road surface, a swing arm 1 supporting it is rocked and displaced upward while rotating a pipe 4 against a center bolt 5, thereby a cylindrical torsion spring is torsionally deformed between a stopper 18 fixed to the pipe 4 and the stopper 19 of a bolt 16. The spring load by this torsional deformation is optionally set against the rocking displacement of the swing arm 1 by the material of an elastic member 30 and the material of a reinforcing member 31 such as fibers reinforcing the elastic member 30. Such setting can be made that the spring load is quickly increased at the rear half of the swing arm 1 to prevent the bottoming of a damper, for example.
