PURPOSE:To minimize the fitting error of control valve, etc., by a method in which a link mechanism consisting of a roller in contact with the cams of spools and side plates to support both ends of the roller is assembled with a bracket in a rocking manner and connected to the control valve body. CONSTITUTION:A control valve body 2 is provided with plural spools 3 having cams 4. A rotatable link mechanism is made up of a roller 6 in contact with the cams 4, side plates 7 and 8 to pivotally support both ends of the roller 6, and the pivotal support point 21 of a bracket 20 provided projectionally from the control valve body 2. The link mechanism fabricated with the vracket 20 is integrally attached to the side of the control valve body 2 with a bolt. The fitting error of the control valve and the link mechanism can thus be minimized. |
