Golf club

Abstract

Disclosed is a golf club capable of allowing a user to properly adjust the striking direction and striking impact for a golf ball by presenting a reference line for accurately striking the golf ball, and simultaneously providing an index for checking the exact movement distance and direction of a club head in take-back and striking actions. The golf club is provided with a shaft, which has a first side surrounded by a grip grasped by a user, and a club head, which is connected to a second side of the shaft to strike a golf ball. The shaft comprises a shaft body including transparent material, and a guide member inserted into the shaft body and having a specific sectional shape such that the guide member guides horizontal movement of the golf club.
