度の充填でも放熱性の改善を大幅にできる。Embodiments of the present invention will be described below with reference to the drawings. First, the structure will be described. The material of the bearing 1 is a linear PPS (polyphenylene sulfide resin) as a base. It is made of FRP (fiber reinforced plastic) containing ethylene polymer resin. Further, the material of the outer housing 2 is made of FRP containing ABS (acrylonitrile butadiene styrene) resin as a base and containing about 30 to 50% by weight. Then, the resin material A is molded into a predetermined shape by a two-color injection molding apparatus in one step using both materials. Since the heat transfer coefficient of carbon fiber reaches 10 to 100 times that of ordinary resin, even if the carbon fiber is filled at about 30%, the heat radiation property can be greatly improved.

ＰＶ値で約１０００に達する場合がある。An electric vacuum cleaner 3 is provided with a drive motor 4 and a turbo brush 5 which can be transmitted by a timing belt 6. The motor shaft 7 of the drive motor 4 is supported by the bearing 1 of the bearing device A attached to the frame 8. Next, the operation will be described. The drive motor 4 which is a drive source for rotating the turbo brush 5 has a capacity of about 12,000.
Extremely high speed of ~ 14000 rpm. Since the bearing load due to the tension of the timing belt 6 is about 1 kg, the PV value may reach about 1000.

向上することができる。The bearing portion A made of resin has a function of ensuring slidability in the inner bearing 1 and a function of heat transfer in the outer housing 2. That is, by combining with CFRP having a high heat transfer property, the generated frictional heat can be quickly radiated to the outside, the storage heat on the sliding surface can be prevented, and the limit PV value can be improved.
