<p>PURPOSE: To enable to assure a smaller angle cleance of a shaft against a same clearance and better guide in the cross direction of a ski, by extending a guiding rib in front of the ski to an area of a guiding bearing of a hinged connecting shaft of a boot, and composing the rib with an enlarged part containing a face bearing in the cross direction for the hinged connecting shaft in the area of a guiding bearing. CONSTITUTION: A guide rib 2 with a constant width 1 contains a first part 3 named 'rearward'. This part 3 contains a tilting part 3a at the rearward, and a horizontal part 3b is followed after this, and a whole cross section is almost trapezoid. In front of the first part 3, the rib 2 contains an enlarged part 4 which with a w idth L is extended to an area of a guiding shaft of a hinged connecting shaft 11. A rotating shaft 11 is beared at a front wall 5 of the enlarged part 4. The width L corresponds to a 'effective' length of the hinged connecting shaft 11.</p> |
