12. The work vehicle according to claim 1 , further comprising:
a brake pedal with which a braking device provided to a traveling unit is operated;
a depression amount detection unit configured to detect a depression amount of the brake pedal;
a main clutch pedal with which a main clutch is operated for connecting and disconnecting power in a middle of a power transmission path between the engine and the traveling unit;
a depression amount detection unit configured to detect a depression amount of the main clutch pedal; and
a controller configured to perform deceleration with the continuously variable transmission in accordance with the depression amount of the brake pedal or the main clutch pedal.
13. The work vehicle according to claim 12 , wherein the controller is configured to perform, when a value detected by the depression amount detection unit for the brake pedal or the main clutch pedal exceeds a first setting value, speed change with the continuously variable transmission for achieving a vehicle speed corresponding to the depression amount, and to make the work vehicle travel at a creeping speed when the value is larger than a second setting value and smaller than a value at a maximum depression position.
14. The work vehicle according to claim 12 , wherein the controller is configured to prioritize, when an accelerator pedal and an accelerator lever are both operated, an operation on the brake pedal.
15. A work vehicle comprising:
an engine;
a continuously variable transmission configured to convert rotational driving force from the engine, the continuously variable transmission having an operation state changeable for changing a speed of the work vehicle starting and travelling;
an operation control device, wherein an acceleration characteristic is adjustable for a case where the work vehicle starts or a traveling speed is changed by operating the operation control device;
