Abstract
Provided are a resin filler tube capable of facilitating manufacture and ensuring rigidity in a bent tube portion, and a manufacturing method thereof. A resin filler tube connects an oil filling port and a fuel tank and includes straight tube portions and bent tube portions. The bent tube portions include a bellows-shaped bent inner portion in which hill portions and valley portions are continuous, and a bent outer portion which is formed by a non-bellows-shaped smooth surface. The valley portion of the bent inner portion has a linear outer peripheral surface parallel to a center line of the bent tube portions in a state in which the bent tube portions are in a straight tubular shape, and the linear outer peripheral surface of the valley portions is formed in an entire circumferential range in which the hill portions are formed.
