Abstract: A production method for a cover attached to an outer ring of a hub unit first prepares a first mold and a second mold which form a cavity filled with a resin material. Next, by a protrusion of the first mold, a nut is supported. Next, when viewed from an axial direction of the nut, in a state where at least a part of the gate of the second mold overlaps an inside of the nut as compared with an outer circumferential surface of the nut, the first mold and the second mold are die-matched. Then, a resin material is injected into the cavity.

Abstract: A wheel bearing apparatus includes an outer ring, an inner shaft member, rolling elements, a cage, and a sealing device. The sealing device includes an annular slinger and a sealing member. The slinger has a first inclined surface provided on a radially outer side and on a side facing the sealing member such that a diameter of the first inclined surface increases toward a first side in an axial direction. The sealing member has a second inclined surface provided on the radially outer side and on a side facing the slinger such that a diameter of the second inclined surface increases toward a second side in the axial direction. The second inclined surface intersects with a virtual extension surface extending radially outwardly along the first inclined surface, and the second inclined surface is continuous with an inner peripheral surface of the radially outer portion.

Abstract: A hub unit includes an outer ring, an inner shaft, rolling elements and a sealing device. The outer ring includes an outer ring body and an outer ring flange. The inner shaft includes an inner shaft body and an inner shaft flange. The outer ring body includes a first portion and a second portion. The first portion is an end part on the outer side of the outer ring body. The second portion is a part of the outer ring body between the first portion and the outer ring flange. The second portion includes an upper build-up portion. The upper build-up portion is formed in an upper part of the second portion and a thickness of the build-up portion is larger than thicknesses of side parts of the second portion. An upper end of the upper build-up portion is higher than an upper end of the first portion.

Abstract: A rolling device for a vehicle includes an inner raceway member including first and second inner raceways; an outer raceway member including first and second outer raceways; first rolling elements disposed rollably between the first inner raceway and the first outer raceway and second rolling elements disposed rollably between the second inner raceway and the second outer raceway; and grease disposed on raceway surfaces of the first inner raceway, the first outer raceway, the second inner raceway, and the second outer raceway and rolling surfaces of the first rolling elements and the second rolling elements. The grease includes a base oil, a thickener, and additives. The grease includes a synthetic oil as the base oil. A kinematic viscosity of the base oil at 40° C. is 20 mm2/s to 50 mm2/s. The additives include a phosphorus compound, a calcium compound, and a hydrocarbon wax.

Abstract: A production method for a cover attached to an outer ring of a hub unit including procedures as follows. A nut is supported by a first protrusion of a first mold. By a second protrusion of a second mold, a core bar including a cylindrical section to be inserted into the outer ring is supported. A resin material is injected into a cavity formed by the first mold and the second mold to form a cover including a nut and a core bar. The cover is detached from the second mold by moving the first mold in a direction of being separated from the second mold. After this, the cover is detached from the first mold by pushing out the cover in a die matching direction with a pin disposed in the first mold.

Abstract: A sealing device includes a core metal that is fitted to the outer ring, and a sealing member that is fixed to the core metal. The core metal has a cylindrical portion that is fitted to the inner periphery of an end portion of the outer ring, an outer annular portion, and an inner annular portion. The sealing member has a covering portion that covers the outer annular portion and the cylindrical portion, and a space is formed between the covering portion and the flange. The sealing member further has an inner lip portion, and an outer lip portion. The covering portion has a deformed portion used to enlarge the space to suppress stagnation of water in the space.
