Abstract

Onto a surface of a cylindrical core body 1 made of synthetic resin, is adhered a heater unit 2 which is formed by adhering, with an adhesive agent, an electric resistance member 4 made of a SUS foil on an inner surface of a flexible electrically insulating plate 3 made of synthetic resin. The electric resistance member 4 is formed by half-punching the SUS foil uniformly applied on the electrically insulating plate into a given configuration and removing an unnecessary portion. The electric resistance member 4 has a small width, a large length and a zigzag shape to increase electric resistance. Both ends of the electric resistance member constitute connecting portions for an electric power supply wire 5 and are arranged side by side at one end of the electrically insulating plate.

Claims

1. A handle grip with heater including a cylindrical or semi-cylindrical core body made of an electrically insulating synthetic resin and a heater unit adhered on an outer surface of the core body, wherein said heater unit includes an electrically insulating plate and an electric resistance member adhered on said electrically insulating plate, said heater unit is bent and is adhered onto the outer surface of the core body, and said handle grip further comprises a molded synthetic rubber body provided to cover the inner and outer surfaces of an assembly of the core body and heater unit.

2. The handle grip with heater according to claim 1, wherein said assembly of the core body and the heater unit has formed therein a plurality of through holes through which outer and inner portions of said molded synthetic rubber body are coupled with each other.

3. The handle grip with heater according to claim 1, wherein said electric resistance member of the heater unit is formed by punching a metal foil into a strip-shape and removing an unnecessary portion.

4. The handle grip with heater according to claim 3, wherein said electric resistance member has a small width, a large length and is zigzag shape, and both ends of the electric resistance member form connecting portions for an electric power supply wire.

5. The handle grip with heater according to claim 1, wherein said electrically insulating plate has formed therein positioning holes and said core body has formed thereon positioning pins which are inserted into said positioning holes.

6. The handle grip with heater according to claim 1, wherein the outer surface of said core body has formed therein supporting grooves extending in a longitudinal direction and said heater unit is fixed in position by inserting side edges of the heater unit into said supporting grooves of the core body.

7. The handle grip with heater according to claim 1, wherein connecting ends of said electric resistance member are arranged to be mutually shifted in a longitudinal direction of the core body, and an electric power supply wire connected to the connecting ends is arranged along an arcuate end line of the core body.

8. The handle grip with heater according to claim 1, wherein an electric power supply wire is connected to both ends of said electric resistance member at connecting portions thereof, and a tubular wire cover made of synthetic resin is provided along an arcuate edge of the core body to cover the electric power supply wire.

9. The handle grip with heater according to claim 8, wherein connecting portions of said electric power supply wire are connected to both ends of the electric resistance member and are covered with said wire cover together with a part of the electric power supply wire.
