Abstract: A golf club with an enhanced degree of freedom with respect to design, and a method for manufacturing the same. A head 1 is formed with a face 3 on the front face, a cavity 9 on a rear face and a shaft attachment portion 8 on one side, to which is connected a shaft 2. If a maximum height of a bottom surface 9A of the cavity 9 in the top-to-sole direction is denoted by H1, and a maximum width thereof in the toe-to-heel direction is denoted by W1, the cavity 9 is formed to satisfy an inequality: H1/W1≳0.6. Further, if a maximum height of the face 3 is denoted by H1, then the cavity 9 is formed to satisfy an inequality: 0.7≲H1/H2≲0.85. Thus, the face 3 can be easily resiliently bent at the time of striking balls, thereby developing a greater repulsive force, elongating travelling distances of balls.

Abstract: A propulsion member (e.g. a bat) has an external switch and an internally disposed transistor which transmits signals when the switch is manually closed. A receiver in a tee mechanism receives the signals and causes a tee in the mechanism to move upwardly from a rest position to an operative position. As the tee moves upwardly to the operative position, an element (e.g. a wiffle ball) moves on a ramp to a supportive position at the top of the tee. When the tee is in the operative position, a player holding the propulsion member swings the member against the ball. This is helpful to young children (e.g. eight (8) years old or younger) in learning how to hit a baseball.
