FIELD: transport. ^ SUBSTANCE: power transmission mechanism 80 coupled handbar 51 with skis 12. First lever mechanism 801 comprises first rotary shaft 52 and second rotary shaft 82 coupled by first rod 81 and fitted on different axles. Second lever mechanism 80b is arranged between second rotary shaft 82 and ski 12. Steering drive booster 60 is mounted on second lever mechanism 80b and integrated therewith, and has drive motor operated in compliance with turn of second rotary shaft 82 coupled with booster rotary shaft 63 to make its output extension. ^ EFFECT: reduced stiffness of first lever mechanism, hence, its weight. ^ 5 cl, 4 dwg |
