Locking structure of steering column device for vehicle
TLDR
In this article, the authors proposed axially and movably fitting an operation lever 25 to a lock bolt 21 which penetrates long holes 31, 39 formed to a fixing bracket and a support bracket 17 formed to movable member 19.Abstract:
PROBLEM TO BE SOLVED: To provide locking structure of a steering column device for a vehicle, significantly reducing the probability of occurrence of half locking. SOLUTION: Locking structure of a steering column device for a vehicle is constituted by axially and movably fitting an operation lever 25 to a lock bolt 21 which penetrates long holes 31, 39 formed to a fixing bracket and a support bracket 17 formed to a movable member 19. At least one of the fixing bracket 15 and the support bracket 17 has a bracket side teeth part (a tilt teeth part 35 or a telescopic teeth part 43), the movable member has a movable side teeth part (a tilt locking teeth part 53 or a telescopic teeth part 55). A specific crest part of at least one crest part out of a plurality of crest parts in the bracket side teeth part or the movable side teeth part is higher than neighboring other crest parts, and the specific crest part is smaller in pressure angle as an angle of a tip than the neighboring other crest parts.
