  • Patent number: 6114668
    Abstract: A heater-installed grip for a vehicle includes substantially semi-cylindrical inner pieces (33.sub.1, 33.sub.2) of a synthetic resin which have a planar heater (34.sub.L, 34.sub.R ; 174.sub.L, 174.sub.R ; 184) wound around an outer periphery thereof and which are integrally embedded in a cylindrical grip body (35) made of a rubber assembled to a pipe-shaped steering handlebar (26) or a throttle pipe (79). In this heater-installed grip, a circumferentially central portion of each of the inner pieces (33.sub.1, 33.sub.2) is formed at a large wall thickness, as compared with circumferentially opposite ends thereof. Thus, the assemblability of the grip body (35) to the pipe-shaped steering handlebar (26) or the throttle pipe (79) is enhanced, while ensuring a die-clamping strength in a process for forming the grip body (35).
