The tube is made of an elastomeric material with a reinforcing material spirally embedded into the tube wall, and at least one of the tubular parts where no spiral reinforcing material exists. The tip end of the reinforcing material which is wound in spiral shape is bent parallel to the inside surface of the tube and inward of the tube for at least one or more pitches of the spiral, and at least the tip of the reinforcing material bent is buried into the inside wall of the tube.
