Abstract
A wheel loader includes a vehicle body frame, a transmission mechanism, a support section, a movable section, a joystick lever, and an urging mechanism. The transmission mechanism transmits a movement of the vehicle body frame. The support section is fixed with respect to the vehicle body frame. The movable section is connected to the transmission mechanism and is movably supported by the support section. The movement of the vehicle body frame is input to the movable section. The joystick lever accepts an operation to move with respect to the movable section by the operation. The urging mechanism adjusts a movement of the movable section with respect to the support section.

A work machine comprising:
- a body;
- a movement transmitter configured to transmit a movement of the body;
- a support section installed with respect to the body;
- a movable section movably supported by the support section, the movable section being connected to the movement transmitter, the movement of the body being input to the movable section;
- an operating member configured to accept an operation to move with respect to the movable section, the operating member including a joystick lever or a steering wheel;
- and
- an urging mechanism configured to adjust a movement of the movable section with respect to the support section, the urging mechanism including a first spring member,
