The wall part includes a pair of edge parts facing each other with the opening therebetween and extending along a first direction, and a plurality of claw parts disposed at each of the pair of edge parts. The pair of edge parts is curved to the inside of the housing. The cover includes through holes disposed correspondingly to the claw parts. The claw part includes a base part protruding from the corresponding edge part and a holding part protruding from the base part along the first direction. The housing sandwiches and holds the cover between an edge part and the holding parts inserted into the through holes in a state where the cover is curved.

Abstract: A golf club head enables the initial velocity of a ball to be increased and enables the carry to be lengthened. In some example structures, the golf club includes a face plate formed from metal and club head body (e.g., a crown and sole) formed from fiber reinforced plastic. A weighted body is provided inside the rearmost portion of the golf club head and a low rigidity portion whose width becomes gradually narrower as it approaches the rearmost portion is provided in the crown extending from the vicinity of the face plate to the rearmost portion.

Abstract: A golf equipment fitting system and a golf equipment fitting program is capable of providing accurate calculation results even when specifications that affect swing time are changed, and of outputting simulation results in a short period of time. The golf equipment fitting system and the golf equipment fitting program calculate a swing response surface and a time response surface using a response surface methodology based on an obtained swing data. Also, the golf equipment fitting system and the golf equipment fitting program calculate the swing data of a golf club that is not used for measurement from the swing response surface and the time response surface, simulate a golf swing based on the calculated swing data, and output the results of simulations.
