This specification discloses a one-way clutch rolling member holder for holding a plurality of rolling members disposed between the annular inner surface of an outer race and the annular outer surface of an inner race and intermittently transmitting a torque, characterized in that the holder has a plurality of holding surfaces disposed between the rolling members, and some or all of the holding surfaces have a planar portion bearing against the annular inner surface of the outer race or the annular outer surface of the inner race. The specification also disclosed a one-way clutch having such holder.

In a one-way clutch bearing having an outer race having an annular inner surface, an inner race having an annular outer surface corresponding to and concentric with the inner surface, and rolling members disposed in an annular space formed between the inner surface and the outer surface, whereby relative rotation of the inner and outer races in one direction is prevented by displacement of the rolling members in the space and a torque is transmitted, holding means for holding the rolling members is provided at a displacement position whereat the rolling members transmit a predetermined transmission torque, and means is provided for decreasing a wedge angle (an angle defined by a line extending from the center of the inner race to the point of contact between the rolling member and the inner race and a line passing through the points of contact between the rolling member and the inner and outer races) at a position before the rolling members arrive at the displacement position.

A one-way clutch comprises an outer race where inner surface is formed with a raceway surface and an annular groove; an inner race whose outer surface is formed with a raceway surface; a plurality of wedge members interposed between the outer and inner races about the annular space defined therebetween; and a retainer comprising an outwardly extended annular projected portion engageable with the annular groove and a pushing member for causing the annular projected portion to elastically press against the annular groove. The retainer member is interposed between the outer and inner races so as to retain the plurality of wedge members, the outer race is provided with a stopper for limiting the displacement of the projected portion after the engagement thereof with the annular grove. The outer diameter of the projected portion is greater than the inner diameter of the raceway surface of the outer race.

The present invention provides a wet multi-plate clutch comprising a clutch case and hub disposed on a same axis, a first friction engagement element disposed in the clutch case, a second friction engagement element disposed on the hub, and a piston for applying an axial load to the first and second friction engagement elements, and wherein a recessed groove is formed in a surface of the piston opposing to the first and second friction engagement elements, and a wave spring is disposed within the recessed groove, and only a portion of the opposed surface at an outer diameter side or an inner diameter side of the recessed groove urges the respective friction engagement elements.
摘要:
A one-way clutch formed between an inner race and an outer race rotatable relative to each other for preventing the relative rotation thereof exceeding a predetermined limit. The permission and prevention of the relative rotation of the two races is accomplished by rollers contained in roller containing grooves formed in the inner race or the outer race. The opposite side walls of each containing grooves for holding the rollers in a predetermined state are formed by a roller holding member mounted to the inner race or the outer race. Engaging portions and engaged portions are formed on the holding member and the rollers, respectively.

A taking lens of a camera includes first and second lens elements. A lens holding frame retains the first lens element on a lens base or a front surface of a shutter unit. In the lens holding frame, a holding frame body is disposed in front of the first lens element. Arm portions are formed to project from a periphery of the holding frame body, have a distance to the lens base when in a free state, are bent resiliently by a retention pin or screws, and are secured to the lens base. Thus, the first lens element is squeezed tightly between the lens base and the holding frame body.

A light emitting apparatus for a bicycle includes a pulse generator for generating pulses having a predetermined period and a predetermined duty cycle, a light emitter for emitting light when a voltage is applied, and a voltage applying apparatus for applying a voltage to the light emitting apparatus in response to the generated pulses, and the pulse generator generates pulses which allows the light emitted from the light emitter to be visually recognized as light continuously emitted, by a person. Namely, the voltage is applied intermittently to the light emitter, such that the light emission by the light emitter can be visually recognized as light continuously emitted. Therefore, by the light emitting apparatus for the bicycle, brighter light can be emitted and power consumption by the circuit as a whole can be reduced, as compared with the prior art.
