    摘要： An ethylene-.alpha.-olefin-non-conjugated diene copolymer rubber composition comprising a low molecular weight component copolymer composed of an ethylene-.alpha.-olefin-non-conjugated diene copolymer having a Mooney viscosity (ML.sub.1+4, 100.degree. C.) of 10 to 150, an .alpha.-olefin content of 30 to 60% by weight and an iodine value of 37 to 65, and a high molecular weight component copolymer composed of an ethylene-.alpha.-olefin-non-conjugated diene copolymer having a Mooney viscosity (ML.sub.1+4, 100.degree. C.) of 100 to 500, an .alpha.-olefin content of 15 to 50% by weight and an iodine value of 3 to 15, the ratio of the iodine value of the low molecular weight component copolymer to the iodine value of the high molecular weight component copolymer being at least 4/1. The above composition can inhibit a gel from being produced during processing and achieve a high degree of cross-linking and is excellent in compression set, shape-retention and sponge surface skin.

    摘要： A rubber composition is disclosed which contains not less than 20% by weight in a rubber component of a block copolymer composed of polymer or copolymer block units (A) and a random copolymer block units (B). The polymer or copolymer block units (A) are obtained by singly polymerizing a conjugated diolefine or copolymerizing the conjugated diolefine and a monovinyl aromatic hydrocarbon with use of a lithium initiator and contains not more than 10% by weight of the bound monovinyl aromatic hydrocarbon. The random copolymer block unit (B) are obtained by copolymerizing the conjugated diolefine and the monovinyl aromatic hydrocarbon and contain 15 to 80% by weight of the bound monovinyl aromatic hydrocarbon. In the block copolymer, (i) the block copolymer contains not less than 10% by weight of each of the block units (A) and the block units (B); (ii) the total content of the bound monovinyl aromatic hydrocarbon is from 10 to 40% by weight; (iii) the average content of the vinyl bonds in the conjugated diolefine portions is from 20 to 70%; and (iv) polymerizable terminals of the block copolymer are reacted with an isocyanate compound.

    摘要： A drive control unit alone can be replaced without detaching an electric power steering apparatus from a gear housing. A motor housing of an electric motor, which outputs assist torque to a steering wheel of a vehicle, and a drive housing of the drive control unit, which controls the driving of the electric motor, are coupled to each other at a mating surface in a surface to surface contact manner, and the drive housing and the gear housing are coupled with each other on the same axis. A location of connection, at which a power supply input terminal block of the electric motor and power supply bus bars of the drive control unit are connected to each other by us of screws, is arranged at a joint location at which the motor housing and the drive housing are joined to each other by screws.
