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

1. A golf club comprising:

a head;

a shaft;

a grip;

a first member detachably attached;

a second member detachably attached; and

a tool capable of being used to detach the first member and the second member,

wherein if a minimum force required to detach the first member from the tool in a connection state of the tool and the first member is defined as F1, and a minimum force required to detach the second member from the tool in a connection state of the tool and the second member is defined as F2,

the force F1 is greater than the force F2.

2. The golf club according to claim 1, wherein the first member is not disengaged under the first member'"'"'s own weight from the tool in the connection state of the tool and the first member;

and

the second member is disengaged under the second member'"'"'s own weight from the tool in the connection state of the tool and the second member.

3. The golf club according to claim 2, wherein the tool further includes a holding mechanism;

and

the first member includes an engaging part capable of being engaged with the holding mechanism.

4. The golf club according to claim 3, further comprising a socket fixed to the head, and a sleeve fixed to a tip part of the shaft,

wherein the first member is a weight body detachably attached to the socket;

and
