  As shown in FIG. 8, a concave portion 146 extending in a substantially triangular shape is formed from the vicinity of the center of the sole portion 140 to the vicinity of the rear end. Each of the three end portions of the recess 146 is in contact with the inner surface of a substantially triangular lid member 144 (see FIG. 7) that engages with the recess 146 and supports pieces 148a and 148b that support the lid member 144. 148c is formed. A screw hole 149 is formed in each of these support pieces. Further, an opening 142 larger than each screw hole is formed between these three support pieces.

  The lid member 144 shown in FIG. 7 is fitted into the recess 146 so as to cover the opening 142. Each of the three end portions of the lid member 144 is formed with a through hole 143 (see FIG. 7) that communicates with a corresponding screw hole 149 in the sole portion 140. The lid member 144 is detachably attached to the sole portion 140 by engaging a screw (not shown) with each through-hole 143 of the lid member 144 and the screw hole 149 corresponding thereto.

  Referring to FIG. 9 showing the inner surface of the head 100, the opening 142 is, as an example, disposed at a distance from the adjacent region 210 where the sole portion 140 and the face portion 120 are adjacent. By placing a weight adjusting material such as resin in the arrangement area 212 extending between the adjacent area 210 and the opening 142, it is possible to adjust the hitting sound generated when the face 120 collides with the ball.

  Moreover, the opening part 142 is arrange | positioned at an interval from the adjacent area | region 214 with which the sole part 140 and the side part 130 adjoin, as an example. By arranging a weight adjusting material such as resin in the arrangement area 216 extending between the adjacent area 214 and the opening 142, the center of gravity and the moment of inertia of the head 100 can be adjusted.

  In the head 100 according to the present embodiment, a weight adjusting material can be disposed at a desired position in the head 100 by inserting a device such as a finger or a nozzle into the head 100 through the opening 142. it can. In particular, since the arrangement area 212 and the arrangement area 216 described above are provided at positions adjacent to the opening 142, the weight adjusting material can be easily and reliably arranged in these areas via the opening 142. .

8 and 9 show that the opening 142 extends from the vicinity of the center of the sole portion 140 to the vicinity of the rear end as an example. However, the opening 142 is disposed at an arbitrary position in the sole portion 140. You may do it. In addition, an object in which the opening 142 is disposed can be at least one of the crown part 110, the face part 120, the side part 130, and the sole part 140. In any case, it is easy and reliable to provide the opening 142 so as to be adjacent to the arrangement area for arranging the weight adjusting material (this arrangement area can be arbitrarily set). This is advantageous because it is possible to dispose a weight adjusting material on the surface.
Furthermore, a plurality of such openings may be formed. In this case, one lid member can be detachably attached to each of the plurality of openings.

The shape of the opening 142 may be any shape including a circular shape, a rectangular shape, a polygonal shape, and the like.
Regarding the size of the opening 142, the larger the opening 142, the easier it is for the user to place the weight adjusting material at the intended position in the head 100 through the opening 142, but the rigidity of the head 100 decreases. It becomes easy to do. Conversely, the smaller the opening 142, the lower the rigidity of the head 100 can be suppressed, but the user is less likely to place the weight adjusting material through the opening 142. In consideration of such circumstances, the size of the opening 142 can be set arbitrarily. For example, the size of the opening 142 is at least a screw so that a user can insert a finger and move the finger freely, or can insert and move a nozzle that injects resin. It is preferably larger than the hole 149. More preferably, when the opening 142 is disposed in the sole portion 140, the size of the opening 142 is about 10% to about 30% (more preferably about 15% to about 20%) of the entire surface area of the sole portion 140. %).

  The lid member 144 may be formed not only in a triangular shape but also in an arbitrary shape including a circular shape, a rectangular shape, a polygonal shape, and the like.

  A convex portion extending along the outer periphery (at least a part or all of the placement region) of the placement region in order to ensure that the weight adjusting material such as resin is disposed in the placement region assumed in the head 100. The entire arrangement area may be formed as a recess so that the entire arrangement area is positioned below the area surrounding the arrangement area.

  As the weight adjusting material, any material including a resin, an adhesive, a seal (a seal with a weight attached), an elastic body, a metal material, and the like can be used. Note that the elastic body, the metal material, and the like can be fixed to the inner surface of the head 100 with an adhesive, a double-sided tape, or the like.

  The center of gravity, moment of inertia, and / or hitting ball of the head 100 can be changed by changing the material and / or thickness of the lid member 144 instead of or by arranging the weight adjusting material. You can also adjust the sound. That is, a plurality of lid members having different materials and / or thicknesses (that is, a plurality of lid members having different masses) are prepared, and a user selects a lid member selected from the plurality of lid members. You may make it attach to the head 100. FIG. In addition, as a material which comprises a cover member, the arbitrary materials containing carbon, a magnesium alloy, an aluminum alloy, a titanium alloy, a stainless steel alloy, a tungsten alloy etc. are mentioned, for example.

  Instead of arranging the weight adjusting material, or by arranging the weight adjusting material and changing the material and / or length of the screw for fixing the lid member 144 to the head 100, the center of gravity of the head 100, The moment of inertia and / or the hitting sound can be adjusted. That is, a plurality of screws having different materials and / or lengths (that is, a plurality of screws having different masses) are prepared, and a user uses a screw selected from the plurality of screws to cover the screw. The member 144 may be fixed to the head 100. The material constituting the screw includes any material including carbon, magnesium alloy, aluminum alloy, titanium alloy, stainless alloy, tungsten alloy and the like.

  At least one inner surface (part or all) of the crown portion 110, the face portion 120, the side portion 130, and the sole portion 140 may be mirror-finished. Thereby, for example, when an opening is formed in the sole part 140, the mirror part 110, the face part 120 and / or the side part 130, which are mirror-finished, are reflected on the inner surface through the opening. By looking at a person's finger (hand), a device such as a nozzle, and / or a weight adjusting material, the weight adjusting material can be more easily and accurately placed at an intended position in the head 100.

  As described above, according to various embodiments of the present invention, at least one (particularly, the sole portion) of the crown portion, the face portion, the side portion, and the sole portion constituting the head is connected to the inside and the outside of the head. An opening for communication is formed, and a lid member covering the opening is detachably attached to the head with a screw. Thereby, the user of the head can remove the lid member whenever necessary (for example, before entering a game) and use a user's hand (finger) or an apparatus for spraying resin or the like through the opening. The weight adjusting material can be disposed at a desired position in the head.
