Abstract: A connector has a first housing (10) with two detection terminals (13) and a second housing (20) with a resilient deforming portion (25). A detection unit (40) is in the second housing (20) and has two connecting portions (42) that rub against the detection terminals (13) in the process of connecting the two housings (10, 20). The connecting portions (42) are connected to the detection terminals (13) when the housings (10, 20) are connected properly. Fixed contact portions (45) and movable contact portions (50) release a shorted state of the connecting portions (42) as the resilient deforming portion (25) is deformed and short the connecting portions (42) as the resilient deforming portion (25) is resiliently restored. A catch preventing structure (51) prevents foreign matter from being caught at the detection contact portions (45, 50) when the housings (10, 20) are separated.

Abstract: A flexing strip (41) is formed on a housing (20). An interference part (63) is formed on a fit-on detector (50). A distinguishing part (46) having a color different from the fit-on detector (50) is formed on the flexing strip (41). The flexing strip (41) interferes with the interference part (63) and deforms while moving the fit-on detector (50) from a wait position to a detection position. The flexing strip (41) is released from an interference state with the interference part (63) and elastically restores to its original state when the fit-on detector (50) has reached the detection position. A position of the distinguishing part (46) relative to the interference part (63) changes before and after a flexing of the flexing strip (41) so that the distinguishing part (46) is exposed and can be seen from a distinguishing position.

Abstract: A method of manufacturing an outer retainer for a one-way clutch having an outward flange at one side edge thereof involves punching out a part of an annular portion having the outward flange by sliding a punch toward an axis of the outer retainer substantially in an axially inner direction from a retainer outer periphery-sided curve portion of the outward flange to a retainer inner periphery-sided curve portion thereof in a way that uses a die and the punch.

Abstract: An outer retainer includes a pair of annular portions facing each other in an axial direction and a plurality of column members connecting the annular portions. A plurality of window portions is formed by the annular portions and the column members, and an outward flange is provided at one side end thereof. The column member between window portions in predetermined positions is cut and the cut portion on the outward flange side is bent radially outward to be an elastic member. Paired cut-away portions are formed in predetermined portions of the outward flange with the elastic member disposed between the paired cut-away portions. In the thus-configured outer retainer, at least three window portions are disposed between the elastic member and the cut-away portion adjacent to the elastic member in the peripheral direction. Column members between paired cut-away portions are bent outward in the radial direction to be enlarged in diameter.

Abstract: An outer retainer for a one-way clutch has a cylindrical portion and a flange portion extending radially outward from an axial end of the cylindrical portion. The flange portion has three or more arc-shaped major parts disposed circumferentially and arc-shaped minor parts, each adjacent two of the major parts being connected to one another through a minor part, the major and minor parts projecting radially outward to different extents, and the arc-shape of the major and minor parts constituting continuously the shape of the outer periphery of the flange portion.

Abstract: In a one-way clutch comprising an outer race, an inner race opposed radially thereto, torque transmitting members interposed between the outer race and the inner race to be inclinable at positions where they are engaged with the inner and outer races to transmit a torque and at positions where they are not engaged with the inner and outer races, a spring member for urging the torque transmitting members in a direction of engaging with the inner and outer races, and cylindrical inner retainer and outer retainer for retaining said torque transmitting members in the circumferential direction at predetermined intervals and controlling their inclination, the outer retainer comprising a cylindrical portion and a flange portion extended axially from one end of the cylindrical portion and radially outwardly, and the cylindrical portion being provided with windows for respectively retaining the torque transmitting members in the circumferential direction at predetermined intervals, the flange portion of the outer reta

Abstract: In a one-way clutch, an inner diameter-side retainer is formed with a radially inward flange while an outer diameter-side retainer is formed with a radially outward flange. The inner race has a portion radially outwardly extended from one end in the axial direction to the more outer diameter side than the outer race. The outer race has a portion radially inwardly extended from one end on the axially opposite side to that of the inner race to the more inner diameter side than the inner race. Those extended portions face each other in the axial direction with the torque transmitting members therebetween. The inner diameter-side retainer engages the inner race on the side of the extended portion of the inner race at the inner periphery of the inward flange, and the outer diameter-side retainer engages the outer race on the side of the extended portion of the outer race at the outer periphery of the outward flange.
