Title:
MANEUVERING DEVICE
Document Type and Number:
Japanese Patent JP3046771
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To surely notify an operator of the absolute value of a manipulated variable for an operating margin or a dangerous area, etc., via the feel change by preparing an interlocking member which deforms an elastic member in accordance with a manipulated variable and changing in steps the manipulating force with a prescribed manipulated variable in regard to the relation between the manipulated variable and the manipulating force.
SOLUTION: When a control lever 2 is tilted around a pitch shaft 6, a cam follower 22 moves toward the tip of a plate spring 23 and also bends dovmward the spring 23. If the bend deformation of the spring 23 is equal to the elastic deformation, a manipulating angle θ and the manipulating force F show a linear relation between them. Thus, the force F proportionally increases as the angle θincreases. Then the force F changes stepwise between F1 and F2 when the follower 22 passes a projecting part 30. In other words, the force F of the lever 2 changes in steps at a prescribed position. Thereby, it is possible to surely make an operator recognize whether a prescribed manipulated variable is secured.
