<P>PROBLEM TO BE SOLVED: To provide a ball screw device which can reliably obtain a seal effect of each seal member even when attaching at least two seal members multiply onto the end part in the axial line direction of a ball screw nut. <P>SOLUTION: A nut screw hole 13 for inside seal member and a nut screw hole 15 for outside seal member are formed on different positions on the end surface in the axial direction of the ball screw nut 2, a phase adjusting attachment hole 14 for inner seal member and a position adjusting attachment hole 18 for outer seal member which are longitudinal in the rotational direction are formed respectively on an inner seal member 4 and an outer seal member 5, a screw member 8 for outer seal member is inserted to a screw member insertion hole 16 for outer seal member formed on an inner seal member 4, while confirming each seal effect by phase-adjusting each of the inner seal member 4 and the outer seal member 5 in the rotational direction, each of a screw member 7 for the inner seal member and a screw member 8 for the outer seal member is screwed to each of nut screw holes 13, 15 and, as a result, each of the inner seal member 4 and the outer seal member 5 can be fixed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
