The shaft insertion hole 101 processed into No. 00 had the same inner diameter from the upper end to the vicinity of the bottom (see FIG. 4), and was larger than the shaft outer diameter by about 0.1 mm. Also,
It is also known that a screw thread is formed on the inner peripheral surface of the shaft insertion hole in order to enhance the adhesiveness with the shaft. on the other hand,
Recently, as a shaft of a golf club, a reinforced plastic mixed with carbon, boron or the like has been used more than a steel shaft, and the number of accidental breakage of the neck has increased accordingly. When the cause of the breakage accident is investigated, as shown in FIG. 5, when the shaft 102 is attached, the shaft 102 is biased into the shaft insertion hole 101 of the hosel portion 100 and is fixed by the adhesive 103. Shaft insertion hole 10
It has been found that the shaft 102 comes into contact with the inlet end of No. 1, the shaft 102 collides with the inlet end (edge) at the time of impact, and the stress is concentrated there, so that the shaft 102 is broken. To eliminate such a cause, chamfer the edge (inner peripheral edge) of the inlet end of the shaft insertion hole, or apply adhesive so that the shaft is evenly positioned in the insertion hole, and carefully mount it.

として取除かれていない。Even if the inlet end of the shaft insertion hole is chamfered, the shaft is still broken when the shaft is mounted unevenly. Further, it takes time and effort to mount the shaft evenly in the holes and requires skill, which is a problem in mass production. further,
Since the outer diameter of the shaft also varies, it is often the case that the inner diameter of the shaft insertion hole is machined to a large size, which may cause the difference between the outer diameter of the shaft and the inner diameter of the shaft insertion hole to become too large. The amount of adhesive increases, and it takes a long time for the adhesive to harden, which makes it difficult to fix the shaft. Therefore, a measure such as sandwiching a small piece of celluloid or the like between the shaft and the inner wall of the shaft insertion hole is taken, but the shaft may be biased by sandwiching the small piece, and the cause of shaft breakage is still removed. Absent.

定部３Ａとは同心位置にある。FIG. 1 shows a cross-sectional shape of a hosel portion 2 which is integrally provided on a metal head 1. The hosel portion 2 has an insertion hole 3 formed therein. The tip side shape of the insertion hole 3 is adjusted to the tip end shape of the shaft 4, and the inner diameter D 1 thereof is formed to be slightly smaller than the outer diameter of the tip end portion of the shaft 4 to fix the tip end portion of the shaft 4. It is formed on the fixed portion 3A. The inner diameter D 1 is preferably smaller than the diameter of the tip of the shaft 4 by about 0.2 mm at the maximum. More preferably, it is reduced by 0.05 to 0.1 mm. The inner diameter D 2 from the upper end of the fixed portion 3A to the upper end of the insertion hole 3 is made larger than the outer diameter of the shaft 4 so that the large diameter portion 3
B is formed. A step portion 3C is formed at the boundary between the fixed portion 3A and the large diameter portion 3B. Further, a stopper portion 3D for receiving a part or the whole of the tip surface of the shaft 4 is provided at the tip of the fixed portion 3A of the insertion hole 3 so as to extend toward the center of the hole of the insertion hole 3. In this example, a flanged stopper portion 3D having a hole at the center is used. Also, the length L 1 of the fixed portion 3A
Is preferably 3 to 10 mm for an iron club. The length L 2 of the large diameter portion 3B is preferably 25 to 32 mm. On the other hand, in the wood club, the length L 1 is 3 to 10 mm and the length L 2 is 29.
It is preferable to set it to ˜36 mm. Further, the large diameter portion 3B and the fixed portion 3A are located at the concentric position.

The adhesive 5 is formed between the inner peripheral wall of the large diameter portion 3B and the outer periphery of the shaft 4. It is provided in the gap. The inner diameter D 1 of the fixing portion 3A is not smaller than the outer diameter of the shaft 4 so as not to insert the shaft 4, the inner diameter D 1 to the extent that if forcibly inserting the shaft 4 shaft 4 can be inserted until the stopper portion 3D is a shaft It is smaller than the outer diameter of 4. An epoxy type adhesive can be preferably used as the adhesive 5. D 2 and the difference between D 1 (D 2 -D 1) is preferably set to 0.1 to 0.6 mm. The difference is more preferably 0.2 to 0.4 mm, and further preferably about 0.3 mm.

This is because the tip end side of the shaft 4 is adapted to be gradually tapered. If the tip side of the shaft 4 has the same diameter, the inner diameter D 1 of the fixed portion 3A may be the same from the upper end side to the lower end side. Further, by providing the stopper portion 3D, it is possible to prevent variation in the insertion amount of the shaft 4.

図れるものである。As described above, according to the present invention, the tip side shape of the insertion hole of the hosel portion provided in the head into which the shaft is inserted and mounted is adjusted to the tip end shape of the shaft, and the inner diameter thereof is also adjusted. Is formed to be slightly smaller than the outer diameter of the shaft tip to form a fixed part that fixes the shaft tip, and the inner diameter from the upper end of this fixed part to the upper end of the insertion hole should be concentric with the inner diameter of the fixed part. In addition, since the large diameter portion is formed by forming it larger than the outer diameter of the shaft and the adhesive is put in the gap formed between the inner peripheral wall of the large diameter portion and the outer circumference of the shaft, the shaft is attached to the hosel portion. The shaft is positioned in the center of the insertion hole by the fixing part until it solidifies, and it is possible to easily and quickly attach the shaft to the hosel part without any skill or effort. Also improved productivity. Further, since the shaft is mounted in the insertion hole without being biased, the breakage accident can be prevented.
