Abstract: A bearing device for a drive wheel, wherein an annular first seal member is disposed in a clearance between a knuckle member and the outer peripheral surface of an outer ring member. A third clearance small in the radial direction and continued by the length of a first annular side part is formed between the second inner diameter surface of the knuckle member and the first annular side part. Thus, water and slurry are prevented from entering into the clearance formed around a hub bearing.

Abstract: A bearing device for a drive wheel having a knuckle member surrounding a part of a cup part through a clearance. An annular first seal member is disposed between the knuckle member and an outer ring member. An opening part is formed between the peripheral edge part of the knuckle member and the large diameter end part of a joint boot. A recessed part formed in the first seal member is installed to be opened toward the joint boot.

Abstract: A fixing band-tightening apparatus comprises a holding section for gripping a shaft section at both ends in an axial direction, the holding section being provided rotatably in a circumferential direction in accordance with a driving action of a rotary driving source, a stopper section arranged in a lateral direction substantially horizontal with respect to the holding section, for positioning a projection of a fixing band in the lateral direction except for a vertical direction, and a band-tightening section for forcibly nipping the projection of the fixing band positioned by the stopper section to tighten the fixing band.

Abstract: When forcibly mounting a fixture attached with a joint boot on an outer circumferential surface of an outer cup, a thick-walled section is pressed between an inclined surface of the outer cup and an annular stepped section of the fixture. Accordingly, the thick-walled section is elastically deformed and in close contact with the inclined surface for effecting sealing function.

Abstract: A housing has, on an outer circumferential surface thereof, a circumferential surface area, a toothed surface area complementary in shape to grooves and teeth of a boot of rubber, and a stopper engagable by tip ends of the boot of rubber and a boot of synthetic resin. The circumferential surface area, the toothed surface area, and the stopper are successively arranged in the order named in the direction in which the boots are installed onto a rotary joint. The housing has an outside diameter at the circumferential surface area which is equal to or greater than an inside diameter of the boot of synthetic resin. The circumferential surface area, circumferential teeth of the toothed surface area, and the stopper are progressively higher radially outwardly in the order named.
