Abstract A thrust bearing device is constructed to comprise a sliding disk; and a sliding shoe member; both having a sliding surface respectively adapted to slidably contact with each other and one of which is arranged to be the rotary side of the bearing device and the other arranged to be the stationary side, the sliding shoe member being a unitary member formed in a special configuration in that it is provided with plural sliding shoes supported on a common base through ribs, each shoe having a flat surface coplanar with the flat surfaces of the other shoes to constitute a common sliding surface of the shoe member. The stationary side of the device is fixed on a motor bracket with an elastic sheet interposed therebetween.
A thrust bearing device for an electric motor lubricated by liquid within a motor casing comprising; a sliding disk having a sliding surface; and a sliding shoe member provided with plural sliding shoes unitarily supported on a common base through respective ribs, each shoe having a flat sliding surface coplanar with the surfaces of the other shoes and adapted to slidably contact said sliding surface of said sliding disk, either one of said sliding disk or said sliding shoe member being arranged to be the stationary side of the thrust bearing device and disposed on a motor bracket with an elastic sheet interposed therebetween and the other being arranged to be the rotary side of the thrust bearing device and fixed to a motor shaft.
