Abstract
A bat includes a handle having a proximate end and a distal end, a barrel having a hollow portion that accommodates the distal end, and a first damping section at least partially sandwiched between the handle and the barrel in the interior of the hollow portion. The first damping section includes a first portion in contact with each of the handle and the barrel in the interior of the hollow portion, and a second portion disposed closer to the proximate end than the first portion, the second portion being in contact with an inner peripheral surface of the barrel and not being in contact with an outer peripheral surface of the handle. In a cross section along a center axis of the barrel, the barrel has a depression depressed relative to the inner peripheral surface in the cross section, the second portion has a protrusion fitted in the depression.
