<p>PURPOSE:To reduce a weight, by a method wherein a spline is formed on an extended end toward the outside of a power screw and a sleeve on which a similar spline is formed is connected with the extended end. CONSTITUTION:A spline 11d is formed on an extended end 11c toward the outside of a power screw 11 and a similar spline 13a is formed on an inner cylinder surface of the extended end 11c. Then a sleeve 13 over which spline fitting of a rotary driving shaft 15 is made is connected with the spline 13a and a dust proof boot 14 is laid between them. With this construction, a part sliding along with a calipers component 4 is turned into a part up to the power screw 11. A sliding part, therefore, can be limited and a weight can be reduced.</p> |
