    • A taper roller bearing includes an inner race, an outer race, taper rollers arranged so as to be rollable between the inner and outer races, and a retainer for retaining the taper rollers, in which a flange portion is provided only on the radially larger side of the inner race. The retainer includes a radially-larger-side annular portion including a hook portion. The hook portion effects hooking so that the flange portion of the inner race is maintained in an assembled state. In a neutral state, the hook portion is kept out of contact with the flange portion. A guide surface portion for guiding the inner race to be incorporated is provided on a radially inner end portion of an outer surface of the hook portion.

    • A retainer made of a synthetic resin for use in a deep groove ball bearing is proposed of which the lubricity has been improved. The retainer includes a cylindrical first split retainer member (41) having a first axial side, and a cylindrical second split retainer member (42) having a second axial side coupled to the first axial side of the first split retainer member (41). Circumferentially spaced apart first and second cutouts (45 and 50) are formed in the first axial side of the first split retainer member (41) and the second axial side of the second split retainer member (42), respectively, which define respective pockets for receiving balls with the split retainers (41 and 42) coupled together. A coupling arrangement (X) is provided between the first and second split retainer members (41 and 42) which is adapted to engage the split retainer members (41 and 42) when the split retainer members (41 and 42) are coupled together, thereby keeping the split retainer members (41 and 42) axially inseparable from each other. With the retainer mounted in a deep groove ball bearing, when the outer race (11) and the inner race (21) rotate relative to each other, since the first and second split retainer members (41 and 42) rotate at different peripheral speeds due to a difference in diameter therebetween, pumping action is produced in the bearing, which causes a forced flow of lubricating oil in the bearing.

    • A card case accommodates a card or the like in a hollow portion formed as a result of attachment of a cover member to a bottom member. The cover member has such a structure as to allow reversal of its opposite sides in its attachment to the bottom member. Reversal of the opposite sides of the cover member changes the depth of a planar recess portion of the cover member, the planar recess portion partially constituting the hollow portion. Accordingly, the card case can cope with encapsulation of cards of different thicknesses.

    • A tapered roller bearing includes a retainer formed with a plurality of trapezoidal pockets. Each pocket includes cutouts formed in the crossbars defining each pocket near the narrow end thereof. A tapered roller is received in each pocket with its small-diameter end facing the narrow end of the pocket. Lubricating oil flowing into the bearing space defined radially inwardly of the retainer can quickly flows through the cutouts into the bearing space defined radially outwardly of the retainer at the narrow end of each pocket. Thus, it is possible to reduce the amount of lubricating oil flowing along the raceway of the inner ring to the large-diameter flange, and thus reduce the amount of lubricating oil remaining in the bearing, thereby reducing the torque loss due to rotational resistance of the bearing resulting from lubricating oil remaining in the bearing.
    • 圆锥滚子轴承包括形成有多个梯形凹部的保持架。 每个口袋包括形成在横梁中的切口,其限定在其窄端附近的每个口袋。 圆锥滚子被容纳在每个口袋中,其小直径端面向口袋的窄端。 流入保持器径向向内限定的轴承空间的润滑油可以快速地流过切口,从而在每个口袋的窄端处限定在径向保持器外侧的轴承空间中。 因此,能够将沿着内圈的轨道的润滑油的量减少到大直径凸缘,从而减少轴承中残留的润滑油的量,从而减少由于旋转阻力引起的转矩损失 轴承中残留的润滑油产生的轴承。
