Golf club head
First Claim
1. A golf club head comprising a head body, an additional member in which a contour shape obtained by a projection onto a plane has a rotational symmetric axis, and a holding mechanism for holding the additional member,wherein the head body has a recess portion in which at least a part of the additional member can be fitted,the holding mechanism is constituted to enable a mutual transition of a holding state in which the additional member is held in the recess portion and a releasing state in which the hold is released,the recess portion inhibits a rotation around the rotational symmetric axis of the additional member in the holding state,the additional member is rotatable around the rotational symmetric axis in the releasing state, anda phase of the additional member in the holding state is changed so that a position of a center of gravity of the head can be varied.

Abstract
A head (2) includes a head body (4), an additional member (6) in which a contour shape obtained by a projection onto a plane has a rotational symmetric axis (z1), and a holding mechanism (28) for holding the additional member (6). The head body (4) has a recess portion (18) in which at least a part of the additional member (6) can be fitted. The holding mechanism (28) is constituted to enable a mutual transition of a holding state in which the additional member (6) is held in the recess portion (18) and a releasing state in which the hold is released. The recess portion (18) inhibits a rotation around the rotational symmetric axis (z1) of the additional member (6) in the holding state. The additional member (6) is rotatable around the rotational symmetric axis (z1) in the releasing state. A phase of the additional member (6) in the holding state is changed so that a position of a center of gravity of the head can be varied.
