According to the present invention there are provided a variable throttle valve and a hydraulic power steering device containing a variable throttle valve. A screw member (64) is screwed into a spool (62) which is axially movably inserted into a housing. The opening of the throttling portion (67) of the variable throttle valve (60) is varied according to the axial shifting of the spool (62) according to the rotation of the screw member (64). The centerline of the screw member (64) is eccentric to the centerline of the spool (62). The eccentricity prevents the spool (62) from rotating together with the screw member (64). <IMAGE> |
