    摘要: A head includes a body member that has an opening, and a face member that includes a striking face and closes the opening. The face member includes a face portion that forms the striking face, and a peripheral portion that extends from a peripheral edge of the face portion toward a back side. The peripheral portion of the face member is welded to the body member. A weld bead that juts from the inner surface of the head is formed at a boundary position between the peripheral portion and the body member. A wall thickness at a face-side end point of the weld bead is greater than a wall thickness at a body-side end point of the weld bead. The peripheral portion has a length of less than or equal to 6 mm.

    摘要: Provided is a GUI display device that is able to explain the movement for holding the wrist cock and the movement for releasing the wrist cock during a golf swing visually in easily understandable manner. The GUI display device includes a display control part. The display control part simultaneously displays, on the GUI screen, a first graphic G1(i) representing a strength with which a wrist cock is held at an i-th timing during a swing motion of a golf club, and a second graphic G2(i) representing the strength with which the wrist cock is released at the i-th timing, where i=1, 2, . . . , N (N being an integer of 2 or more).

    摘要: In a head, a center vertical cross section passing through a face center satisfies the following (a) and (b):
    (a) when a boundary point between an inner surface of a crown portion and an inner surface of a face portion is defined as a CF inner surface boundary point, a curvature radius of a head inner surface at the CF inner surface boundary point is 6.0 mm or greater and 10.0 mm or less, and the head thickness at the CF inner surface boundary point is 2.0 mm or greater; and

    (b) when a spot located 10 mm apart from the CF inner surface boundary point toward the crown side is defined as a spot C10, the head thickness reduces gradually from the CF inner surface boundary point to the spot C10, and the head thickness at the spot C10 is 1.0 mm or less.
