PURPOSE: To ease a posture of a hand or an arm of a player for gripping a ball hitting-out handle by providing horizontally or obliquely the ball hitting-out handle in a recessed part formed between overhang parts.

CONSTITUTION: On both the left and the right sides of the front lower part, overhang parts 3, 4 for overhanging obliquely to the front are formed, and on the horizontal surface 6 of the bottom face of a recessed part 5 formed between the overhang parts 3, 4, a handle 45 is provided, and its rotary shaft is set to the vertical direction. Or the bottom face of the recessed part 5 formed between the overhang parts 3, 4 is formed to the inclined surface 6a inclined forward to the front, the handle 45 is provided on the inclined surface 6a, and its rotation axis is made oblique toward the forward direction of the front against the vertical direction. In such a way, it is unnecessary for a player to bent a wrist so as to throw it out in order to grip the handle 45, and by stretching an arm in a state that the palm remains turned down, the handle 45 can be gripped and turned in a natural state. Moreover, since a hand can be placed in the handle 45 or the bottom face of the recessed part, weight of the arm applied to a player's shoulder can be reduced.
