A thrust roller bearing cage () includes a thrust roller bearing () and a plurality of pockets () accommodating rollers (). The thrust roller bearing cage () includes: a first cylindrical portion () extending in a direction of a rotation axis (); a first disc portion () continuous with the first cylindrical portion () and extending in a radially outward direction; and a second cylindrical portion () continuous with the first disc portion () and extending in the direction of the rotation axis (). The first cylindrical portion (), the first disc portion (), and the second cylindrical portion () are formed in an area located radially inside the pockets (). The first disc portion () has a through hole ().

A thrust roller bearing cage () a thrust roller bearing () and a plurality of pockets () accommodating rollers (). The thrust roller bearing cage () includes: a radially outer area bent portion () formed by bending an area located radially outside the pockets () inward in a radial direction; and projecting portions () that are formed in a tip end of the radially outer area bent portion () and project inward in the radial direction so as to contact end faces () of the rollers () accommodated in the pockets. Radially outer edges () of the pockets () are located radially outside base end parts () of the projecting portions ().

A thrust roller bearing cage () includes a thrust roller bearing () and a plurality of pockets () accommodating rollers (). The thrust roller bearing cage () includes: a radially outer area bent portion () formed by bending an area located radially outside the pockets () inward in a radial direction; and projecting portions () that are formed in a tip end of the radially outer area bent portion () at positions aligned with the pockets () and project inward in the radial direction beyond radially outer edges of the pockets () so as to contact end faces () of the rollers () accommodated in the pockets (). The projecting portions () have a width that is &#x2153; or more and &#x2154; or less of the width of the pockets ().

A thrust roller bearing cage () is a cage () provided to a thrust roller bearing and having a plurality of pockets () that house needle rollers (). The cage () includes projections () that are formed by bending a radially outer area of the cage () inwardly along the radius and that project inwardly along the radius toward a radially outer area of the pockets () to make contact with end faces () of the rollers (). The projections () have corners () that make contact with the end faces () of the rollers (). The corners () are press-flattened.

A thrust roller bearing cage () of the present invention is included in a thrust roller bearing () and includes a plurality of pockets () accommodating rollers (). The thrust roller bearing cage () includes: a radially outer area bent portion () formed by bending the cage () inward in a radial direction along an annular groove formed at a position radially outside the pockets (); and projecting portions () that are formed in a tip end of the radially outer area bent portion () at positions aligned with the pockets () and project inward in the radial direction beyond radially outer edges of the pockets () so as to contact end faces () of the rollers () accommodated in the pockets (). A trace () of the groove is left at a position along which the cage is bent.

A power plant for a vehicle of the present invention includes an electric motor attached to a transmission housing attached to an engine. The electric motor is attached to the side of the transmission housing toward the engine and is connected to the engine interposed by an anchor point. When the engine is viewed in a crankshaft direction, a line connecting the anchor point and the center of gravity of the electric motor intersects a line extending along a direction in which the electric motor vibrates due to vibration of the engine in the absence of an anchor point.

Power plant for a vehicle

A thrust roller bearing includes a plurality of rollers, a retainer, an annular first track ring having a track surface, an outer periphery flange part, and a first claw part, and an annular second track ring having a track surface, an inner periphery flange part, and a second claw part. Bearing internal gaps to allow the eccentric rotation of the first track ring and the second track ring are provided between the outer periphery flange part and an outer edge part of the retainer, and between the inner periphery flange part and an inner edge part of the retainer. In addition, at least one of the first and second claw parts is a projection part formed by a bending process. Furthermore, an edge part of the retainer opposed to the projection part has a first slope part formed at a corner part on the side opposed to the track surface, and a second slope part having a radial length relatively shorter than that of the first slope part, and formed at a corner part on the opposite side in a thickness direction.

An airbag is formed of two base fabrics. An adhesive agent is pasted with some width on one of the base fabrics and then another of the base fabrics is put on the one of the base fabrics. The two fabrics are adhered together to form the airbag. Pasting start/end portions of the adhesive agent is set at a gas introducing portion of the airbag. Pasting start/end points (terminal ends of the start/end portions) is located outside a path in the gas introducing portion through which a gas is introduced into an inside of the airbag. According to an airbag with the airbag, assembling workability of the airbag can be improved.

Airbag device and production method thereof

Provided is a mixed aluminum hydroxide powder suitable as a filler to be filled into a resin or the like, particularly suitable in an application where the filler is desired to be filled in a large amount, and enabling the production of a molded article excellent in strength properties. The mixed aluminum hydroxide powder is obtained by mixing an aluminum hydroxide powder X having an average secondary particle diameter in the range of 5 to 16 &#x3bc;m and a shape coefficient of 4 or less, and an aluminum hydroxide powder Y having an average secondary particle diameter in the range of 0.5 to 2.0 &#x3bc;m and a shape coefficient of 4 or less, the mixed aluminum hydroxide powder being adjusted so as to have an average secondary particle diameter in the range of 0.9 to 12 &#x3bc;m.

Mixed aluminum hydroxide powder

A thrust roller bearing comprises a plurality of rollers and a disk-shaped retainer having a plurality of pockets for holding the plurality of rollers and having an outer flange part bent in a rotation axis direction. The inner surface of the outer flange part forms the outer wall surface of the pocket and the outer wall surface of the pocket is processed by the ironing.
