Abstract

PURPOSE:To simplify regulation of a load force and to compact structure, by a method wherein a pair of load nuts mounted to a load screw through a repulsion spring are engaged with each other and are assembled in an axially slidably locked manner. CONSTITUTION:A small load nut 06 is formed such that it can be contained in a protruding casing 61a of a large load nut 61, and the load nuts 60 and 61 are intercoupled through a repulsion spring 62. A lock pin 63 protruded from the load nut 61 is engaged with a slide groove 60a engraved in the outer surface of the load nut 60, and the lock pin and the slide groove are separable away from each other and are integrally formed for rotation energization. A pair of the load nuts 60 and 61 receive rotation of a load screw 58 and are axially slid and moved within a load sleeve 59 in a state to block rotation, and generate a high load by means of energizing forces separated from each other through the force of the repulsion spring 62. By planning the lead of the load screw 58 to a value lower than that of a ball screw 48, a constituting part can be compacted.
