Document Type and Number:
Japanese Patent JP2023127637
Kind Code:
A
Abstract:
To provide a ball hitting part capable of reducing energy loss in the ball hitting part, and improving repulsive force.SOLUTION: A ball hitting part 5 includes: a core material 7 decentered and arranged on one side in a radial direction; a first elastic body 15 having one side part 19 in the radial direction supported by the core material 7, and the other side part 21 in the radial direction facing in the radial direction to the core material 7 through a space part 23, and having relatively small elastic hysteresis; and a second elastic body 17 covering outside in the radial direction of the other side part 21 of the first elastic body 15 to form a ball hitting surface 5a, and having relatively large elastic hysteresis.SELECTED DRAWING: Figure 3
