<p>Object To provide a steering apparatus for vehicles which is made up of a reduced number of parts. Solving Means A fastening bolt (45) has a step (47) disposed between a head (46) and a threaded surface (49) and fitted in a pipe insertion hole (24). A stem pipe (14) is firmly tightened and supported by a slot tightening mechanism. A step (47) is tightened when the stem pipe (14) is reduced in diameter under compressive forces. Only a tightening force required to keep the fastening bolt (45) from loosening is applied to the fastening bolt (45). In other words, since the fastening bolt (45) firmly supports the stem pipe (14) which requires a greater tightening force and the fastening bolt (45) is tightened by only a tightening force required to keep the fastening bolt (45) from loosening, the step (47) of the fastening bolt (45) does not need to be more rigid than necessary. Effect Since a nut for keeping a bolt from loosening is not required, the number of parts is reduced.</p> |
