Abstract
A hot air nozzle includes a leading-end face 2 having an outlet, and at least one side face 3 extending between the leading-end face 2 and a base end 4. The leading-end face 2 has a shape that makes a lengthwise direction α and a widthwise direction of the leading-end face 2 distinguishable, and has a center section 22 in the lengthwise direction α that protrudes relative to two opposite ends 23 in the lengthwise direction α. The outlet extends along the protruding shape of the leading-end face 2.
