Abstract
A third axis a3 is an axis which is perpendicular to a straight line, the straight line connecting a tip of a tip portion 5b of a fourth operating lever 5 tilted to the maximum extent to one side in a first direction and the tip of the tip portion 5b of the fourth operating lever 5 tilted to the maximum extent to the other side, and passes through a tilt pivot point c which is a pivot point of a tilt of the fourth operating lever 5. A first actuator 72 and a second actuator 73 of a first operating mechanism 7 are disposed at least partially overlapping each other when viewed in the direction of the third axis a3.
Claims4
A work machine operating mechanism configured to tilt, based on an operation command, an operating lever for controlling an operating amount of a work machine according to a tilt angle and a tilt direction, the work machine operating mechanism comprising:
- a first direction guide member configured to tilt the operating lever in a first direction;
- a second direction guide member configured to tilt the operating lever in a second direction intersecting the first direction;
- a first direction actuator configured to generate driving force for tilting the operating lever through the first direction guide member based on the operation command;
- and
- a second direction actuator configured to generate a driving force for titling the operating lever through the second direction guide member on the basis of the operation command, wherein
- a reference axis is a line perpendicular to a straight line, the straight line connecting a tip of the operating lever tilted to a maximum extent to one side in the first direction or the second direction and the tip of the operating lever tilted to a maximum extent to the other side, the line passing through a tilt pivot point, the tilt pivot point being a pivot point of a tilt of the operating lever, and
- the first direction actuator and the second direction actuator are disposed at least partially overlapping each other when viewed in a direction of the reference axis.
