Abstract:

PURPOSE: To increase the speed of a hit ball and to enable a game to be played and continued long without much exhaustion of physical strength by fixing a handle grip which is formed in an oblong, arbitrary shape of configuration with a common directional efficiency to a longitudinal direction of a handle to a main shaft set at right angles to a plane of the handle, and by making a rotary element a rotary mechanism on the main shaft at either at least or both of an upper part and a lower part of the handle grip with it as a center.

CONSTITUTION: One end of a main shaft 3 is fixed to a plane of a handle 1 by a screw 4 and the like, and the other end of the main shaft 3 is elongated, on which a handle grip 5 is put and fixed, and that is also fixed to the handle 1. The shape of the handle grip 5 is in common with that of the longitudinal direction of the handle 1 and the shape is made long in breadth to give a directional efficiency to the longitudinal direction of the handle. The main shaft 3 of an upper part of the handle grip 5 is put on an outer casing 7 with a bearing intervened between the main shaft 3 and the outer casing 7. In this case, when the outer casing is made of synthetic resin, a bearing can be omitted. To the upper end plate of the main shaft 3, a screw 4 is fitted so that a rotary element 6 may not come off, over which the upper rotary element 6 is engaged with the upper part of the handle grip 5 free to be rotated.
