Abstract
A golf club head includes a weight object and a weight object receiving portion that is provided on an outer surface of the head and in which at least a part of the weight object is housed. The weight object or the weight object receiving portion includes a shape change mechanism that enables the weight object or the weight object receiving portion to change a shape of itself. The weight object receiving portion includes: a rotational force applying part that applies a rotational force on the weight object as a reaction generated when the weight object is pressed by the shape change; and a rotation prevention part that is located at a position abutting against the weight object when the rotational force is applied and that stops the weight object from being rotated by the rotational force and prevents rotation of the weight object.
