| titleOfInvention | Metal bat and method of manufacturing the same |
| abstract | (57) [Abstract] [Purpose] A sound deadening property having a foam layer on the inner wall surface of a metal bat body, in which the specific gravity continuously changes from a low specific gravity to a high specific gravity from the inner wall surface toward the center of the bat, Provided are a metal bat having excellent vibration damping properties and excellent durability, and a method for manufacturing the same. [Configuration] A method of manufacturing a metal bat comprises: (i) a step of inserting a supply pipe of a foamable resin raw material into the inside of the bat body from a head or a grip end of a hollow metal bat body; (ii) a step of applying a foamable resin raw material to the inner wall surface of the bat while rotating the bat body and / or the supply pipe, (iii) The step of removing the supply pipe, heating the bat body from the outer periphery to form a foam layer in which the specific gravity continuously changes from small to large toward the center of the bat body, (iv) the head of the bat body Alternatively, it includes a step of fixing the grip end. |
