1. 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.
