Abstract: A spout assembly for a packaging bag for improving the prevention of oxidation to an inner content and discharging such content at a desired amount. The spout assembly mounted to the bag body includes a spool to move along the axial direction of the spout assembly and an urging member having an outer peripheral surface fixed to the inner peripheral surface of the spout assembly and adapted to urge the spool toward the bag body side. A check valve allows the inner content to flow only from the bag body side toward the mouth portion side. The urging member has a seat surface for the spool and the urging member presses the spool against the seat surface to shut off the flow of the inner content, and when an inner pressure of the bag body or a suction force of the mouth reaches a predetermined value, the spool separates from the seat surface.

Abstract: The present invention provides a man-driven vehicle equipped with a cover structure practically covering a whole of the vehicle wherein the cover structure is provided with an openable and closable door way substantially comprising a door, a detachable cover, a rotatable cover, and a slide cover cooperating one with another so as to facilitate a driver to get on or off the vehicle. The cover structure additionally comprises a ground contacting skirt and a floor panel so that the vehicle can be comfortably driven even in adverse weather with the cover structure closed and, particularly in fine weather, the vehicle also can be driven with the cover structure opened.

Abstract: An apparatus of foot pedal working type for health maintenance equipped with a DC generator wherein electric current generated by the DC generator adapted to be driven by foot pedal working force is supplied to an electric device via a DC/DC converter, characterized in that the generated electric current supplied from the DC/DC converter to the electric device is controlled to increase or decrease and thereby a reaction force necessary for foot pedal working causing the DC generator to generate the electric current is controlled to increase or decrease.
