Head cover for golf club

Abstract

A shaft protecting portion of a head cover is formed of a knit fabric, having a head inlet/outlet opening at a lower portion thereof. An opening/closing portion, which is open at the head inlet/outlet opening, is formed in a lower portion of the shaft protecting portion. A diameter of the head inlet/outlet opening is increased owing to expansion of the knit fabric when the opening/closing portion is opened by hand, and the diameter of the head inlet/outlet opening is automatically reduced (i.e., restored to the former diameter) when the opening/closing portion is released so that the head cover can be easily put on the head. After the head cover has been put on the head, there is no fear of the head cover being detached from the head even if the opening/closing portion is not locked by a stopper such as a fastener or a planar fastener.

1 . A head cover for a golf club, comprising: 
 a head protecting portion to be put on a club head; and    a shaft protecting portion to be put on an attachment side of a shaft attached to the club head;    wherein the shaft protecting portion is formed as a thin and long cylinder of a knit fabric, having a head inlet/outlet opening at a lower end thereof;    a lower portion of the shaft protecting portion formed of a knit fabric is provided with an opening/closing portion which is open at the head inlet/outlet opening; and    a diameter of the head inlet/outlet opening is increased owing to expansion of the knit fabric when the opening/closing portion is opened, and the diameter of the head inlet/outlet opening is automatically reduced owing to contraction of the knit fabric when the opening/closing portion is released.
