Abstract

A golf club 2 includes a head 4, a shaft 6, a grip 8, a first member m1 detachably attached, a second member m2 detachably attached, and a tool 102. A minimum force required to detach the first member m1 from the tool 102 in a connection state of the tool 102 and the first member m1 is defined as F1. A minimum force required to detach the second member m2 from the tool 102 in a connection state of the tool 102 and the second member m2 is defined as F2. The force F1 is greater than the force F2.

Claims
