<p>PURPOSE:To perform proper engagement of the rack tooth and the pinion tooth of a track by a method wherein rack teeth inclined based on a line crossing right angles with a longitudinal direction are formed in a straight rail and the rail is curved to form the curve part of the track. CONSTITUTION:A belt-like long block 5a fixed along the longitudinal direction of a straight rail and having rack teeth 5 crossing a longitudinal direction at right angles and formed in the long block is used as the straight part of a track 1. The long block 5a, which is fixed along the longitudinal direction of the straight rail and has the rack teeth 5 inclined based on a line crossing the longitudinal direction at right angles and formed in the long block, and is curved, is used as a curved part. Since the inclined rack tooth 5 is twisted according to the degree of a curve like the rack tooth not inclined, a pattern wherein displacement by an angle responding to an offset amount of the pinion tooth 7 resultantly occurs, and the pinion tooth 7 is accurately engaged with the rack tooth 5.</p> |
