Golf club

A golf club comprising:

• a shaft;
• a head having a hosel hole;
• a sleeve fixed to a tip end portion of the shaft;
• and
• a screw capable of being screw-connected to the sleeve, wherein:
• the sleeve includes at least one engaging projection part;
• the head includes at least one engaging recess part;
• a rotation of the sleeve with respect to the hosel hole is regulated based on an engagement between the engaging projection part and the engaging recess part;
• a falling-off of the sleeve from the hosel hole is regulated based on a connection between the screw and the sleeve inserted to the hosel hole;
• the engaging projection part includes a first side surface located on a side which receives a rotating force caused by hitting, a second side surface located on an opposite side to the first side surface, and an outer surface extending between the first side surface and the second side surface, wherein an edge is between the first side surface and the outer surface and an edge is between the second side surface and the outer surface;
• the engaging recess part includes a first opposed surface opposed to the first side surface, a second opposed surface opposed to the second side surface, and an inner surface opposed to the outer surface;
• the engaging projection part includes a tapered projection part formed such that a distance between the first side surface and the second side surface decreases toward a tip end of the sleeve, wherein a thickness of the engaging projection part in a radial direction of the sleeve decreases toward the tip end of the sleeve;
• the tapered projection part engages the engaging recess part;
• a maximum width of the tapered projection part is equal to or greater than an opening width of the engaging recess part;
• and
• the outer surface includes an outer inclination surface inclined so as to go toward a radial-direction inner side as approaching to the tip end of the sleeve.
