To provide a grip with excellent touch, feeling of fitting and gripping property by forming the grip of a foamed body on the surface of which a cell layer wherein the cell diameter, cell density and the foaming ratio have each a specified value is exposed.
A grip 1 has a cylindrical appearance and one end part thereof is closed as a bottom part and another end part is opened as an opening part 3 and the outer diameter is gradually decreased from the bottom part 2 to the opening part 3 and it is formed of a foamed body with a foaming ratio of at most 2 times as a whole. This foamed body is prepd. by foaming a rubber or a resin such as natural rubbers, isoprene rubber, ethylene-propylene-diene rubbers, polyvinyl chloride resins and silicone resins, and a double layered structure with a cell layer and a skin layer 5 is used. The cell layer positioned on the surface of the grip 1 is a layer wherein a no. of cells of fine air bubbles exist and is formed in such a way that there exist extremely large no. of extremely fine cells with a cell diameter of at most 100 μm and a cell density of at least 109/cm3.
