Abstract: A head 4 includes a head body m1 and a recessed-part forming member b1. The head body m1 includes an opening hs1 for a recessed part, and a receiving part x1 formed on at least a part of a periphery of the opening hs1 for a recessed part. The recessed-part forming member b1 is fixed to the opening hs1 for a recessed part. A recessed part R is formed on an outer surface of the head by the recessed-part forming member b1. The recessed-part forming member b1 is formed separately from the head body m1. The recessed-part forming member b1 includes an outer extension part y1. The outer extension part y1 is supported by the receiving part x1. The head 4 is hollow.

Abstract: A golf club 2 includes a face angle adjusting mechanism 20 provided on a sole s4. The face angle adjusting mechanism 20 has a grounding member 22 which can be protruded from the sole s4, a storing part 24 storing the grounding member 22, and a coil spring 26 pressing the grounding member 22 so that the grounding member 22 is protruded from the storing part 24. The grounding member 22 is set so that a protruding amount of the grounding member 22 from the sole s4 is varied depending on its position of rotation angle about its axis in a state where the grounding member 22 is stored in the storing part 24. By changing a position of rotation angle of the grounding member 22, the protruding amount of the grounding member 22 is changed thereby to change a face angle.
