A method of manufacturing a universal joint includes: temporarily assembling a bearing, which supports a shaft portion of a joint spider such that the shaft portion is rotatable, with respect to a through-hole and the shaft portion by press-fitting the bearing to a first position in the through-hole of a yoke; and clinching, after the bearing is temporarily assembled, a portion of the yoke around the through-hole, and pressing the bearing deeper into the through-hole with a clinched portion formed by the clinching to press-fit the bearing to a second position located deeper than the first position in the through-hole.

Manufacturing method and manufacturing apparatus for universal joint

A fastening mechanism fastens a first side plate to a second side plate by a fastening member. A boss with a rhombic cross-section of the fastening member is inserted into a telescopic-adjust long groove of the second side plate. An outer periphery of the boss includes a first corner part and a third corner part each forming an obtuse angle and facing each other. The first corner part is disposed on an upper side in an axial direction, on a lower side in a tilt direction, while the third corner part is disposed on a lower side in the axial direction, on an upper side in the tilt direction. A width across the first corner part and the third corner part is shorter than a groove width W of the telescopic-adjust long groove.

Steering device

A first plate of a stationary bracket has long holes which extend parallel to a column movement direction, and through which large-diameter portions of suspension bolts are passed. The inner circumferences of the long holes include: recessed curved surface portions of end portions in a direction opposite to the column movement direction; first inner edge portions which are on the side of a middle position between the long holes; and second inner edge portions. In a secondary collision, when the one suspension bolt slides over the first inner edge portion of the long hole, for example, a gap is formed between the other suspension bolt and the second inner edge portion of the long hole.

A key ring according to embodiments is press-fitted onto a steering shaft (column shaft) at a position that is radially outer side of a fit portion at which multiple shaft members that constitute the steering shaft (column shaft) are fitted to each other, and that is substantially the same as the position of the key ring in the axial direction. When a lock bar is inserted into a lock bar insertion portion formed in an outer periphery of the key ring, the key ring restricts rotation of the steering shaft.
