    摘要： A waterjet propulsion system for a watercraft including a duct disposed on the bottom of the watercraft with the opening facing backward, a device to produce waterjet in the duct and a steerable nozzle fitted on the duct opening. Inside the nozzle, a flow guide extending forwardly beyond a supporting axis for the nozzle is formed integrally with the nozzle. For the flow guide, a plate or plates fitted vertically respectively including or parallel to the nozzle centerline or a cylinder mounted coaxially with the nozzle can be preferably employed.

    摘要： A substantially flat-shaped board type carrier (8) is placed on a carrier frame mounted on the front and/or rear of a straddle type four wheeled all-terrain vehicle. The carrier surface (8A) on which baggage is placed is provided with numerous lateral anti-slip projections (8e) that are parallel to one another and expand outward. Of the parts comprising the carrier frame, at least the front main frame and rear main frame are made of pipe and support the carrier by being fitted into the fitting grooves formed by the ribs on the bottom surface of the carrier.
