LINEAR MOTION GUIDE MECHANISM

WIPO Patent Application WO/2012/144371

A1

A linear motion guide mechanism (1) used to guide a member which linearly moves forward and backward. The linear motion mechanism (1) is provided with a housing (2), a screw shaft (3) which is supported by the housing (2) so that the screw shaft (3) can rotate about the axis (O) and can move in the direction of the axis, and a linear motion body (5) which includes a nut (4) engaged with the screw shaft (3) and which is moved in the direction of the axis of the screw shaft (3) by the rotation of the screw shaft (3). Guide surfaces (15, 15A, 15B, 15C, 15D) extending in the direction of the axis of the screw shaft (3) are provided to the housing (2). Each two of the guide surfaces (15) are disposed as a pair. The two guide surfaces (15) of each pair are not parallel to each other and face back to back. The linear motion body (5) is provided with guided bodies (16) respectively in contact with the guide surfaces (15).
