PROBLEM TO BE SOLVED: To collect dirt outside a filter and facilitate cleaning of the dirt by forming a periphery surface of a filter frame in spherical surface and press- fitting the spherical surface shaped frame into slanted passage hole. SOLUTION: A mesh 100 is fit in a filter 99 and an outer side frame 102 is formed in a shape that it is spherical shaped as a whole and upper and lower part, of the sphere is cut in plane. A flow passage through which plane surfaces 102a, 102b are penetrated and the mesh 100 is assembled in nearly middle of the flow passage 104. Outer diameter of the spherical frame 102 of the filter 99 is larger than inner diameter of a large diameter part 62a of a supply passage hole 62 of a hydraulic reaction control valve 50 and the filter 99 is fixed in the large diameter part 62a by press fitting it. Whereby, cleaning of dirt collected by press fitting the filter at a steering control valve side can be facilitated. |
