Golf club

A golf club comprising:

• a head having a hosel part;
• a shaft;
• and
• a reverse-tapered engagement part disposed at a tip portion of the shaft,
• wherein:
• the reverse-tapered engagement part includes a sleeve having a reverse-tapered shape and being fixed to the tip portion of the shaft, and a reverse-tapered outer surface;
• the hosel part includes a hosel hole, and a hosel slit which is provided on a side of the hosel hole and enables the shaft to pass through the hosel slit;
• the hosel hole has a reverse-tapered inner surface having a shape corresponding to a shape of the reverse-tapered outer surface;
• either one of the reverse-tapered outer surface and the reverse-tapered inner surface has an abutting engagement surface;
• the other of the reverse-tapered outer surface and the reverse-tapered inner surface has a first abutting surface and a second abutting surface;
• a first state in which the abutting engagement surface abuts on the first abutting surface is formed when the reverse-tapered outer surface is set on a first rotation position, and a second state in which the abutting engagement surface abuts on the second abutting surface is formed when the reverse-tapered outer surface is set on a second rotation position;
• and
• an axial direction position of the reverse-tapered outer surface with respect to the reverse-tapered inner surface in the first state is different from that of the second state, and a club length is adjusted by the difference.
