Abstract
A first operation mechanism 3 includes a first driving source 30 which generates a driving force based on a drive command and a first driving mechanism 32 which inclines a left-side traveling pedal 1c by the driving force from the first driving source 30. The first driving mechanism 32 has a first abutting portion 32a which abuts a pedal surface of the left-side traveling pedal 1c and a first driving unit 32b which inclines the left-side traveling pedal 1c by inclining the first abutting portion. The first driving unit 32b is arranged in a position shifted to a lateral side from a space in which the first abutting portion 32a moves.
Claims6
A work machine operation mechanism inclining a pedal based on a drive command, the pedal being rotated about a rotation axis line as a center and being inclined in a front-rear direction for controlling an action of a work machine in accordance with inclination, the work machine operation mechanism comprising:
- a driving source which generates a driving force based on the drive command;
- and
- a driving mechanism which inclines the pedal by the driving force from the driving source, wherein
- the driving mechanism has an abutting portion which abuts a pedal surface of the pedal as a surface which is stepped on when an operator performs an operation and a driving unit which inclines the pedal by inclining the abutting portion,
- the driving unit is arranged in a position shifted to a lateral side from a space in which the abutting portion moves, and
- the abutting portion includes a front side abutting portion which extends from a side of the pedal toward the pedal side and abuts the pedal surface on a front side than the rotation axis line and a rear side abutting potion which extends from the side of the pedal toward the pedal side and abuts the pedal surface on a rear side than the rotation axis line.
A work machine operation mechanism inclining a pedal based on a drive command, the pedal being rotated about a rotation axis line as a center and being inclined in a front-rear direction for controlling an action of a work machine in accordance with inclination, the work machine operation mechanism comprising:
