レバー装置。[Claims for Utility Model Registration] 1. The control lever is provided with an operating body that rotates together with the lever, and a reaction piston is provided below the operating body so that the upper end surface of the piston is in opposition to the lower surface of the operating body. The control lever device is configured to be movable up and down while in contact with a force receiving surface, and configured to apply load pressure based on the operation of the control lever to the reaction piston as back pressure to apply an operation reaction force. A control lever device characterized in that the reaction force receiving surface of the operating body is formed into an inclined surface that slopes downward from the side near the center of rotation of the operating body to the opposite side. 2 A claim characterized in that a pressure reducing valve is provided below the operating body in line with the reaction force piston, and the surface on the lower surface of the operating body for operating the pressure reducing valve is formed as an inclined surface in the opposite direction to the reaction force receiving surface. 1. The control lever device according to 1.
