Abstract
An angle adjuster for a golf club shaft includes a pressing part that can advance and retreat towards and away from a space between two pressing force receiving parts. The pressing force receiving parts include grooves configured to receive a golf club shaft. When the pressing part is advanced against the golf club shaft, a bending force is applied to the shaft at a bending location on the shaft that lies between the pressing force receiving parts. This occurs while the shaft is received in, the receiving grooves of the pressing force receiving parts.
