ABSTRACT:
A golf club which helps master a proper swing path is provided. A golf club includes a hollow shaft; a club head at a tip portion of the shaft; a grip at a base end portion of the shaft; and a balance-shifting unit which increases a swing balance of the golf club. The balance-shifting unit includes a partitioning portion which divides an inside space of the shaft into a first portion on the base end portion side and a second portion on the tip portion side; and a balancing material. The partitioning portion includes a first shifter portion which allows the balancing material held in the first portion to move to the second portion side in association with a swing; and a second shifter portion which allows the balancing material on the second portion side to return to the first portion. The golf club further includes a balance holder.
