  • Bearing mechanism and a pump
    Patent number: 6779990
    Abstract: A bearing mechanism comprises a shaft rotatably supported by a bearing accommodated in a cylindrical bearing accommodating portion. The shaft is applied with varying load in response to a slidable movement of a pair of pistons so as to be displaced in a direction. The bearing is displaced corresponding to the displacement of the shaft being applied with the varying load. The bearing mechanism further comprises a biasing means. The biasing means biases the bearing to be always in contact with at least a portion of an inner peripheral surface of the cylindrical bearing accommodating portion in the other direction different from the direction in which the bearing is displaced in accordance with the varying load.
