Abstract: Disclosed herein is a straddle type vehicle that uses resin seat rails, and in which attachment parts of footrests for an occupant of a rear seat of a tandem seat are provided to fastening parts of a member connecting right and left seat rails. The straddle type vehicle may include: resin right and left seat rails extending in a vehicle longitudinal direction; a middle connection member connecting the seat rails to each other; a tandem seat assembled to the seat rails and footrests for an occupant of the tandem seat respectively coupled to the right and left seat rails. A connection part of the middle connection member of the seat rails is provided within a range obtained by vertically extending an outer edge of an attachment part of the footrest coupled to each of the seat rails in side view.

Abstract: In the vicinity of a front end of a plate-shaped member of a fiber reinforced resin material having long fibers, to suppress deterioration in strength due to waviness of the long fibers during press-molding. The plate-shaped member is formed by a discontinuous fiber reinforced resin having long fibers. A flat surface part of the plate-shaped member is provided with a hole part, and a side wall is integrally formed to a semicircular end of the flat surface part located closer to the hole part. The side wall is arranged in a region between an opening edge of the hole part closer to a front end, and the front end so as to extend around its outer circumference.

Abstract: A molding die for molding a foam molding in a cavity constituted in the interior by matching a stationary die and a movable die, the cavity being able to be filled with molten resin, and the foam molding being produced using counter-pressure. A seal material for sealing the pressurization area for the counter pressure technique between the stationary die and the movable die is provided to the molding die, and the seal material is constituted of an elastic foam that has open cells.

Abstract: A method of molding a resin molded product wherein a resin material in a molten state containing a forming agent is injected through a gate into a cavity of molding die thereby forming the form-molded product, wherein the gate communicating with the cavity of the molding die is continuously formed to the rising wall portion of the foam-molded product; the rising wall portion is provided with a rib at a position apart from the gate at a predetermined distance; a foaming of the molten resin material injected from the gate into the cavity is suppressed at a region corresponding to the upstream side portion of the foam-molded product, while the foaming of the molten resin material is promoted at a region corresponding to the downstream side portion of the foam-molded product.

Abstract: In a state that a fixed mold and a movable mold are matched with each other, a molten resin is filled into a cavity. In this state, a movable nest is set in a position retired from a mold matching surface of the movable mold by a predetermined distance, its surface in a fixed mold side functioning as a cavity surface, and the molten resin is filled as far as a nest fitting portion. Then, only the movable mold is made to move backward in a mold opening direction (in an arrow direction in the drawing) by the predetermined distance to release a pressure and foam the molten resin, whereby a foam molded product is molded in which a strength of part thereof is improved.
