摘要： A cam device includes a drive cam, a follower, a holding cam, and a restriction roller. The drive cam reciprocally rotates. The follower intermittently reciprocate linearly by the drive cam. The holding cam is rotationally driven integrally with the drive cam. The restriction roller is provided on the follower and restricts a movement of the follower by coming in contact with the holding cam. The holding cam separates from the restriction roller and the holding cam is in a holding release state, when the drive cam is in an engaged state with the follower.

摘要： A telescopic shaft includes: an inner shaft where a pair of recessed grooves that face each other in a direction perpendicular to an axis and extend in an axial direction are formed; an outer shaft where a pair of recessed grooves that face each other in the direction perpendicular to the axis and extend in the axial direction are formed; a plurality of rolling bodies that are disposed between each of the recessed grooves and the corresponding recessed groove so as to form a line in the axial direction; a pair of stoppers; and a buffer body unit. Each of the stoppers restricts falling of a rolling body at an end portion of the corresponding line from the corresponding recessed groove of the inner shaft. The buffer body unit integrally includes a pair of buffer bodies, and a connection portion that connects the pair of buffer bodies.

摘要： A cross shaft joint includes a bearing cup, a cross shaft, and a joint yoke. The bearing cup includes a cylindrical portion in which an opening portion for receiving a shaft portion is formed in one end of the cylindrical portion in an axis direction, and a bottom portion that closes the other end of the cylindrical portion in the axis direction. The bearing cup is press-fitted into the fitting hole and supports the shaft portion through a rolling element so that the shaft portion is able to rotate. The bearing cup is fitted onto the shaft portion inside the fitting hole and holds the rolling element with the shaft portion. A diameter of an inner peripheral surface of the cylindrical portion is smaller on the opening portion side than the bottom portion side in a free state of the bearing cup before being press-fitted into the fitting hole.

摘要： A telescopic shaft includes an inner shaft, an outer shaft, a plurality of rolling bodies that are disposed between recessed grooves of the inner shaft and the outer shaft and form a line in an axial direction, a stopper, and a buffer body. The stopper restricts falling of the rolling bodies from the recessed groove of the inner shaft. The buffer body is interposed between the stopper and a rolling body at an end portion of the line. An end surface of the buffer body includes an inclined abutment portion that is inclined with respect to a plane perpendicular to an axis of the inner shaft. The abutment portion abuts against the rolling body at the end portion of the line at a stroke end of the inner shaft with respect to the outer shaft.

摘要： A spline telescopic shaft includes an inner shaft having an outer tooth surface, and a cylindrical outer shaft having an inner tooth surface and arranged to fit to the inner shaft slidably in an axial direction of the inner shaft. Either one of the outer tooth surface and the inner tooth surface includes a first resin coating. The other of the outer tooth surface and the inner tooth surface includes a second resin coating. The second resin coating is formed by processing for sliding an intermediate member for manufacturing the inner shaft and an intermediate member for manufacturing the outer shaft in the axial direction, to transfer a part of a resin material provided in the intermediate member for manufacturing the shaft including the one tooth surface for forming the first resin coating to the intermediate member for manufacturing the shaft including the other tooth surface.

摘要： A piston is displaced in a cylinder to pre-load an antifriction bearing. This displacement of the piston is effected according to the amount of working oil confined in a working oil chamber. This oil pressure generating device is equipped with a working oil reservoir to pressurize the working oil in the reservoir for reserving the working oil to be fed to the chamber. An orifice is disposed in a working oil passage for providing the communication between the reservoir and the chamber. The clearance, which is established in the portion of antifriction bearing by the extension or contraction of a shaft due to a temperature change, is absorbed by such displacement of the piston, as is effected by the flow of the working oil between the reservoir and the chamber via the orifice. This orifice acts as a high resistance to and a high rigidity against the abrupt fluctuation in the direction opposite to the pre-loading direction.

摘要： A speed-increasing spindle device in an assembly structure in a separable form of device main body and shank, capable of using a coupling bolt of large diameter, high in rigidity, and sufficient in strength. The head of the coupling bolt is rotatably engaged in a bolt head engaging part provided at one side of the device main body and shank, while the threaded part of the coupling bolt is engaged with a screw hole provided at the other side of the device main body and shank, and the engaging part for rotary operation tool provided on the outer end plane in the axial direction of the coupling bolt confronts outside through the insertion hole of the shank. The bolt head engaging part has a bolt head accommodating space larger than the maximum hole diameter permitted in the shank in terms of strength, and therefore the shaft diameter of the coupling bolt may be set, at least, as large as the maximum hole diameter of the shank.
