A working machine includes: an operator’s seat; and at least one pedal to be operated by being stepped on with a foot, or with feet. The at least one pedal is disposed ahead of the operator’s seat. The at least one pedal includes a pedal body extending in a predetermined direction, a pedal shaft having an axis intersecting the predetermined direction and supporting the pedal body in such a way as to allow pivotal motion of the pedal body around the axis, and a tread surface provided on an upper surface of the pedal body and being a surface on which an operator places the foot. The tread surface is sloped such that a height from the pedal body decreases gradually from a portion closer to a big toe of the foot of the operator placed thereon toward a portion closer to a little toe.

One embodiment of a bidirectional pedal assembly includes a base structure connectable to a vehicle structure and a pedal support member pivotally mounted on the base structure to be pivotable around an axis of rotation from a rest position in a first direction and in a second direction opposite to the first direction. First and second spring elements to urge the pedal support member to its rest position. First and second frictional mechanisms are disposed between the pedal support member and the first and second springs, such that the first and second frictional mechanisms, respectively, moves with the pedal support member and transmits force from the pedal support member to one of the first and second spring elements. Each frictional mechanism is arranged to increase a frictional resistance to retard pivotal movements of the pedal support member upon force being transmitted through the respective frictional mechanism.

Disclosed is a vehicle accelerator pedal that may include a cylindrical hinge unit, a lever unit having one side configured to operate in a first direction and another side formed to correspond to an inner circumferential edge of the hinge unit and configured to operate in a second direction opposite the first direction. An outer circumferential edge may be configured to come into close contact with an upper inner circumferential edge of the hinge unit such that a moment of force is applied in a first rotation direction by the hinge unit. An elastic unit having one side may be configured to elastically support one side of the lever unit, the other side formed to correspond to the inner circumferential edge of the hinge unit. An outer circumferential edge may be configured to come into close contact with a lower inner circumferential edge of the hinge unit.
