It extends along the grip portions 2 and 3. Moreover, FIG. 2 schematically shows the configuration of the present proposal. The traveling operation part is a combination of the fixed grip parts 2 and 3, the grip covers 4 and 5, and the levers 6 and 7.

[0010]

Embodiment A first embodiment of a heating device of the present invention will be described with reference to FIGS. 2 to 5.

As shown in FIG. 2, FIG. 3 and FIG. 4, inside the brake lever 6 and the clutch lever 7, along the levers, there are provided passages 8A, 9A having a circular cross section on the front side and the rear side of the motorcycle, respectively. Has been formed. The distal end portions of these passage portions are communicated with the curved passage portion 10, and the circulation passage 11A is formed in the entire passage portions.

Reference numerals 14 and 25 are a radiator and an engine of the motorcycle, respectively. The radiator 14 has a coolant inlet 14A for taking in the heated coolant from the engine 25 and a coolant outlet 14B for delivering the cooled coolant to the engine 25. Further, the engine 25 of the motorcycle has a cooling liquid outlet 25A for sending the cooling liquid heated inside, and a cooling liquid inlet 25B for taking in the cooling liquid cooled by the radiator 14 into the engine 25 as described later. The cooling liquid outlet 25A of the engine 25 and the cooling liquid inlet 14A of the radiator 14 are a radiator hose 15, and the radiator hose 16 different from the cooling liquid outlet 14B of the radiator 14 and the cooling liquid inlet 25B of the engine 25 is used. It is connected.

As shown in FIG. 2, the base ends of the passage portions 8A and 9A respectively have a radiator hose 15 and a radiator hose 15 via couplings 12A and 12B (see FIG. 3 in particular) and pipes 13A and 13B. The cooling liquid intake port 16A of the radiator 14 and the cooling liquid delivery port 14B of the radiator 14 are connected to each other. These end portions of the radiator hoses 15 and 16 will be referred to as a cooling liquid inlet portion 26 and a cooling liquid outlet portion 27, respectively. These cooling liquid inlet portion and cooling liquid outlet portion are respectively referred to as the cooling liquid of the radiator. It can also be provided in the intake port 14A and the radiator coolant outlet port 14B. Further, a flow rate control valve 17 such as a throttle valve is provided in the pipe 13A connecting the cooling liquid inlet portion 26 and the passage portion 8A.

As in the case of the levers 6 and 7, as shown in FIGS. 2, 3 and 5, inside the fixed grip portions 2 and 3, a pair of passage portions having a circular cross section along these grips are provided. 18A and 19A are formed. The distal end portions of these passage portions are communicated with each other by the curved passage portion 20, and the circulation passage 21A is formed in the entire passage portions. As shown in FIG. 2, the base ends of the passage portions 18A and 19A are connected to the cooling liquid inlet portion 26 and the cooling liquid outlet portion 27 via the couplings 22A and 22B (see FIG. 3) and the pipes 23A and 23B, respectively. It is connected. Further, a flow control valve 24 such as a throttle valve is provided in a pipe 23A connecting the cooling liquid inlet portion 26 and the passage portion 18A.

Next, the operation will be described. In the radiator 14, the pressure and temperature of the cooling liquid are higher in the cooling liquid inlet 14A or the cooling liquid inlet 26 than in the cooling liquid outlet 14B or the cooling liquid outlet 27. Therefore, when the engine 25 of the motorcycle is rotating, most of the cooling liquid heated in the engine 25 passes through the cooling liquid outlet 25A of the engine, the radiator hose 15, and the cooling liquid inlet portion 26 to the radiator. Although it enters 14 and is cooled, a part of the cooling liquid is introduced into the passage portion 9A of the levers 6 and 7 and the passage portion 18A of the grip covers 2 and 3 through the pipes 13A and 23A, and the curved passage portions 10 and 20. It is folded back to the other passage portions 9A and 19A.

In this way, the heated cooling liquid entering the circulation passages 11A and 21B heats the levers 6, 7 and the fixed grip portions 2, 3 and the grip covers 4, 5 around them. That is, the liquid is heated, the temperature is lowered, and the liquid is discharged to the cooling liquid outlet 27 through the pipes 13B and 23B. Therefore, in the circulation passages 11A and 21A, the temperature of the cooling liquid in the passage portions 8A and 18A becomes higher than that of the cooling liquid in the other passage portions 9A and 19A. Therefore, in the levers 6 and 7, the hot passage 8A is located on the front side of the motorcycle rather than the passage 9A, so that the operator's fingers are warmed more efficiently, and the grip covers 4 and 5 are kept warm. The aisle 18A is arranged on the rear side of the motorcycle more than the aisle 19A so that the grip cover portion, which is in contact with the palm of the operator, is heated to efficiently heat the palm of the operator. Further, by controlling the flow rate control valves 17 and 24, the supply amount of the heating / cooling liquid from the cooling liquid inlet portion 26 to the circulation passages 11A and 21A is adjusted to control the temperature of the levers 6 and 7 and the grip covers 4 and 5. Can be adjusted arbitrarily.

A second embodiment of the heating device of the present invention will be described with reference to FIGS. 2, 6 and 7. Two passage portions 8B, 9B of the circulation passage 11B formed in the brake lever 6 and the clutch lever 7 and two passage portions 18B of the circulation passage 21B formed in the accelerator grip portion 2 and the fixed grip portion 3 are provided. 19B is the same as the first embodiment except that the cross section of 19B is a half moon shape as shown. In the case of the second embodiment, the cross-sectional surface of the passage portion is formed into a half-moon shape in this manner to increase the contact area between the outer peripheral portions of the levers 6 and 7 and the fixed grip portions 2 and 3 and these passage portions, There is an advantage that the heat quantity of the cooling liquid in the passage portion is effectively transmitted to the lever and the grip cover.

In FIG. 2, when the fixed grip portions 2 and 3 and the levers 6 and 7 are hollow, the annular passages 11B and 21B can be replaced with U-shaped pipes.
