Abstract: A structure of golf club storage case includes first and second case portions that are openable/closable with respect to each other. The first and second case portions both form a receiving space, and comprise at least one rack and a plurality of receptacle seats arranged inside the receiving space. The rack forms a plurality of notches corresponding to the receptacle seats. Each receptacle seat forms an insertion space, which receives and retains therein at least two resilient clamp plates that oppose each other. To stow a golf club, a head of the golf club is inserted into the insertion space of one of the receptacle seats to be clamped and positioned by the two resilient clamp plates, while a shaft of the golf club is received in the respective notch of the rack so that the golf club is securely stowed in the first and second case portions.
