ている。In addition, a pair of terminals 3 on the power source side are provided on the bottom of the fitting recess 11 corresponding to the terminals 27 and 28 of the heat dissipation conductor 19 and the conductor 22, respectively.
1,32 are provided. Each of the terminals 31 and 32 is formed in a flat tubular shape, and when the heating element 12 is fitted into the fitting recess 11, the heat dissipation conductor 19 and the electrical conductor 2 inside the tubular shape of the terminals 31 and 32.
The terminals 27 and 28 on the second side are fitted together to be electrically connected.

部が負荷に接続されるようになっている。One terminal 31 on the power source side, which is connected to the terminal 27 of the heat dissipation conductor 19, is welded to the rim core metal 4 of the rim portion 3, and the rim core metal 4 is the spoke shown in FIG. Part 2
It is connected to the metal boss 8 of the boss portion 1 via the spoke core metal 7 of this, and since this boss 8 is conducted to the negative terminal of the battery, one electrode of each heating element 20 is connected via the heat dissipation conductor 19. The part is adapted to be connected to the load.

成形前に接着剤やバンドでリム芯金４及びスポーク芯金
７に固定しておく。Reference numeral 37 denotes a heat-resistant tube that surrounds the lead wire 34 and protects the lead wire 34 from heat when the covering body 5 is formed. Before the covering body 5 is formed, an adhesive or band is used to bond the rim cored bar 4 and the spoke cored bar. It is fixed at 7.
したがって、スイッチ35をオンすると各発熱素子20に通
電され、各発熱素子20が発熱して各放熱通電体19が暖め
られ、温度が上昇すると各発熱素子20に用いた正特性サ
ーミスタの抵抗が増加して発熱量が減少し、所定の温度
で平衡状態となってその温度を維持する。Therefore, when the switch 35 is turned on, each heating element 20 is energized, each heating element 20 generates heat to heat each heat dissipation conductor 19, and when the temperature rises, the resistance of the positive temperature coefficient thermistor used for each heating element 20 increases. As a result, the amount of heat generation is reduced, and the temperature is maintained at an equilibrium state at a predetermined temperature.
この際、各発熱素子20の熱はリム部３の表面に近い放熱
通電体19に直接伝えられるので、その熱がリム芯金４に
奪われ難く、熱を効率的に利用できるため、使用開始時

小型の正特性サーミスタを用いることができる。At this time, the heat of each heat generating element 20 is directly transferred to the heat dissipation conductor 19 near the surface of the rim portion 3, so that the heat is not easily taken away by the rim core bar 4 and the heat can be efficiently used. It is possible to use a small-sized positive temperature coefficient thermistor whose temperature rises quickly, consumes less power, and is inexpensive.

に貼着してある。In addition, as shown in FIG. 1, the cross-sectional structure of the natural leather 6 covering the surface of the rim portion 3 provided with the heating element 12 is, as shown in FIG. 1, a papillary layer 41 having a dense tissue with a small space on the outer surface and a tissue on the inner surface side. The mesh layer 42 is an elastic layer having many coarse and fine spaces, and the mesh layer 42 on the inner surface side is impregnated with an adhesive 43 such as silicone RTV rubber as a sealant having thermal conductivity and elasticity. The natural leather 6 is covered with an adhesive layer 44 made of an adhesive 43 such as silicone RTV rubber formed on the inner surface of the mesh layer 42, and the cover body 5 on the surface of the rim portion 3 and the cover body 24 on the surface of the heating element 12 are provided.
It is attached to.

昇すると、発熱体12の熱は、熱伝導性を有する接着剤43
により、速やかに天然皮革６の表面に伝わり、これによ
って、天然皮革６の表面温度が速やかに上昇するように
なっている。Therefore, when the switch 35 is turned on and the temperature of the heating element 12 rises, the heat of the heating element 12 is heated by the adhesive 43 having thermal conductivity.
As a result, it is quickly transmitted to the surface of the natural leather 6, and thereby the surface temperature of the natural leather 6 is quickly raised.

従来と比べて、速やかに上昇するようになっている。That is, the net-like layer 42 on the inner surface side of the natural leather 6 that covers the surface of the rim portion 3 has a rough tissue and many fine spaces, unlike the dense papillary layer 41 on the outer surface side. , It is difficult to transfer the heat of the heating element 12 to the surface of the natural leather 6,
In particular, the inner surface of the mesh layer 42 that is in contact with the heating element 12 is fluffed by the processing, so that the number of voids becomes very large and the thermal conductivity further deteriorates as it is, but here,
Since the thermal conductivity is improved by the adhesive 43 having thermal conductivity, the heat of the heating element 12 is quickly transferred to the surface of the natural leather 6, and the surface temperature of the natural leather 6 is as shown in FIG. ,
Compared with the past, it is rising faster.

るため、リム部３を把持した感触も良好となる。Further, since the adhesive 43 impregnated in the mesh layer 42 of the natural leather 6 has elasticity in addition to thermal conductivity, it does not impair the elasticity of the mesh layer 42 as an elastic layer, and the adhesive Layer 44
As a result, the adhesion between the natural leather 6 and the covers 5, 24 is improved, and the feel of gripping the rim portion 3 is also good.
なお、この実施例は、カバー体が天然皮革６の例である
が、他の実施例として、カバー体に合成皮革を用いるこ
ともできる。In this embodiment, the cover body is an example of natural leather 6, but as another embodiment, synthetic leather can be used for the cover body.

表面に伝えることができ、合成皮革50の表面温度を速や
かに上昇させることができる。That is, as shown in FIG. 6, the cross-sectional structure of the synthetic leather 50 is such that the outer surface is a skin layer 51 made of a dense material such as vinyl chloride resin, and the inner surface has a coarse and fine space such as a woven or non-woven fabric. Since it is the base cloth layer 52 as an elastic layer made of a material, like the net-like layer 42 on the inner surface side of the natural leather 6,
When the base cloth layer 52 is impregnated with the adhesive 43 such as silicone RTV rubber as a sealant having thermal conductivity and elasticity, the thermal conductivity is improved, so that the heat of the heating element 12 is quickly transferred to the surface of the synthetic leather 50. Therefore, the surface temperature of the synthetic leather 50 can be quickly raised.

る。The adhesive 43 impregnated in the base fabric layer 52 of the synthetic leather 50 is
Since it has other elasticity in thermal conductivity, it does not impair the elasticity of the base cloth layer 52 as an elastic layer, and moreover, the base cloth layer 52
By attaching the synthetic leather 50 to the covering body 5 on the surface of the rim portion 3 and the covering body 24 on the surface of the heating element 12 through the adhesive layer 44 formed on the inner surface of the synthetic leather 50 and the covering body 5, Since the adhesion of 24 is also improved, the feeling of gripping the rim portion 3 is also improved.

果を奏する。Further, in the above-described embodiment, the silicone RTV is used as the sealant with which the mesh layer 42 of the natural leather 6 and the base cloth layer 52 of the synthetic leather 50 are impregnated.
Although the adhesive 43 such as rubber is used, the present invention is not limited to this, and the same action and effect can be obtained by using an adhesive such as silicon grease as the sealant.
そして、上述した実施例では、リム部３の全周をカバー
体としての天然皮革６あるいは合成皮革50で被覆した
が、発熱体12部分だけを被覆してもよい。Further, in the above-described embodiment, the entire circumference of the rim portion 3 is covered with the natural leather 6 or the synthetic leather 50 as the cover body, but only the heating element 12 portion may be covered.
さらに、上述した実施例は、リム部３の被覆体５に形成
