摘要： A power transmission shaft is interposed between a first shaft section and a second shaft section. The power transmission shaft comprises: a cylindrical section rotated integrally with a shaft section and formed cylindrically; a through hole disposed in the cylindrical section and penetrated radially with respect to a rotational axial line, each of a pair of vehicle side rotational shaft sections having an engagement groove disposed on an outer peripheral side of the pair of vehicle side rotational shaft sections and extended in a direction around the rotational axial line and the engagement groove being exposed from the through hole; and a retaining ring (circlip) disposed to enclose at least a portion of the outer peripheral side of the cylindrical section, a portion of the retaining ring being inserted into the through hole from the outer peripheral side of the cylindrical section and being engaged with the engagement groove.

摘要： A propeller shaft as a power transmission shaft is provided between vehicle-side first second shaft parts, and a first tube as a first shaft member is connected to the first shaft part through a first joint member and to the second shaft part through a second joint member. The first tube is connected to the first joint member through a first collar member and to the second joint member through a second collar member. The first collar member includes a first main body part exposed from a first end portion of the first tube, and a first insertion part inserted into the inside of the first end portion. In at least the first collar member, the maximum value of the outer diameter of the first main body part is set to be no greater than the maximum value of the outer diameter of the first insertion part.

摘要： The first constant-velocity joint has an inner ring member, an outer ring member housing the inner ring member, and balls, which are installed in raceway grooves formed at prescribed intervals in a circumferential direction in the outer ring member and which extend along an axial direction, for transmitting rotational torque between the inner ring member and the outer ring member. Furthermore, the constant-velocity joint is formed so that one of the inner ring member and the outer ring member connects to an attaching member installed to a vehicle side with a spline, and so that the other of them connects to a power transmission shaft. In outside wall of the outer ring member, an engagement groove is formed so as to engage with an engagement member applied to connection or release thereof in a range avoiding positions corresponding to the raceway grooves in an axial direction or a circumferential direction.

摘要： A propeller shaft includes a shaft section connected between an input shaft and an output shaft via respective constant velocity joints, wherein the input shaft is connected to a drive source of a vehicle, and the output shaft is connected to driving wheels. The constant velocity joint includes a circlip-restricting surface to engage with a circlip provided in an outer peripheral surface of the input or output shaft, for restricting movement of the first or second shaft in an axial direction. The circlip-restricting surface is implemented by a first inclined surface and a second inclined surface, wherein the second inclined surface is closer to a rotational axis of the shaft section, and wherein the first inclined surface has an acute angle with respect to the axial direction, and the second inclined surface has a smaller angle with respect to the axial direction.

摘要： Apparatus, such as a propeller shaft, includes an outer circumferential portion or outer race to rotate as a unit with an internal shaft (serving as the propeller shaft), an inner circumferential member or inner race to rotate as a unit with an external shaft and a plurality of balls disposed between the outer race and inner race, for transmitting rotation therebetween. A sleeve rotating as a unit with the inner race includes an inside cavity for receiving the external shaft. The sleeve is coated with a coating formed on an inside circumferential surface.
