1. A traveling unit comprising:
a driving wheel;
an idler wheel; and
a crawler belt wound around the driving wheel and the idler wheel and including a plurality of track shoe plates,
wherein the track shoe plates each have a first surface and a second surface located on a side opposite to the driving wheel and the idler wheel relative to the first surface,
the track shoe plates each have a first projecting section on the second surface,
a first side surface of the first projecting section is inclined relative to a perpendicular line perpendicular to the first surface at an angle greater than a winding angle of the track shoe plates relative to either the driving wheel or the idler wheel,
the track shoe plates each have a through hole,
the first side surface of the first projecting section has a depression depressed around the through hole, and
a wall surface of the depression extends from the distal end of the first projecting section toward the first surface and is inclined from the perpendicular line perpendicular to the first surface at an angle greater than the winding angle of the track shoe plates.
