Abstract: Provided is a structure that makes it possible to reduce the number of components. The present invention provides a structure including a resin-molded body and a torsion spring. The resin-molded body includes a front wall and a rear wall spaced apart from each other and a peripheral wall connecting peripheries of the front wall and the rear wall. The resin-molded body includes first and second plate-shaped portions and a hinge portion. The first and second plate-shaped portions are rotatably coupled to each other with the hinge portion. The hinge portion is formed by making the rear wall concave toward the front wall to form a hinge concave portion and welding the rear wall to the front wall. The torsion spring includes first and second arms and a coil portion provided therebetween. The first arm is slidably supported by the first plate-shaped portion. The second arm is supported by the second plate-shaped portion.

Abstract: A resin panel according to an embodiment includes a core material, a reinforcing material, a skin material covering the core material and the reinforcing material, and a fastened member. A reinforcing material has a first plate provided on a front surface of the core material, a second plate provided on a back surface of the core material, and a connecting plate connecting the first plate and the second plate. The fastened member is attached to the skin material by a fastening member penetrating the skin material and the first plate or the second plate of the reinforcing material.

Abstract: A sandwich panel includes a reinforcement member having a recess formed to extend in a longitudinal direction over a predetermined length and open laterally. The thermoplastic resin core material has a rectangular flat board-like shape, and includes a protrusion which is disposed on a peripheral side surface portion thereof and which is capable of being laterally press-fit with respect to the recess. The protrusion has opposing surfaces respectively opposing mutually opposed inner surfaces of the recess, the opposing surfaces being oriented so as to protrude from the peripheral side surface portion. At least one of the opposing surfaces is provided with a plurality of protuberances disposed at an interval in the longitudinal direction. Each of the protuberances has a predetermined height from the opposing surfaces enabling the protuberances to tightly contact the inner surfaces of the recess at the time of press-fitting.

Abstract: A rectangular thin panel conveyance unit includes a plurality of sets of four corner modules, and vibration suppressing bodies for rectangular thin panels in a fixed shape. The corner module has a support surface to support each corner portion of the rectangular thin panel from a lower side. At each corner portion, stacking the corner modules in a vertical direction stacks a plurality of rectangular thin panels in the vertical direction. The vibration suppressing bodies have a thickness equal to or less than the distance between the support surfaces of the corner modules vertically adjacent to one another; and are disposed on each of a top surface and an inferior surface of the rectangular thin panel such that the vibration suppressing body faces a planar portion of each rectangular thin panel to restrict vertical amplitude of vibration of the rectangular thin panel within a predetermined range.

Abstract: The thin panel conveyance unit used for piling up and conveying a plurality of rectangular thin panels includes: resin cushion spacers inserted between the rectangular thin panels, each resin cushion spacer having a load-receiving upper surface for receiving load of the rectangular thin panel disposed above and a placement lower surface placed on an upper surface of the rectangular thin panel disposed below, and having an end part provided with a positioning body for the resin cushion spacer; a pallet having an upper surface configured to allow the rectangular thin panels to be piled up thereon; and a protection sleeve surrounding the piled rectangular thin pallets. The upper surface of the pallet is provided with a peripheral groove in which the protection sleeve can be fitted.

Abstract: A rectangular thin panel conveyance unit that prevents damage of a plurality of rectangular thin panels while conveying the plurality of rectangular thin panels that are stacked so as not to contact one another. A rectangular thin panel conveyance unit includes a plurality of sets of four corner modules, and vibration suppressing bodies for rectangular thin panels in a fixed shape. The corner module has a support surface to support each corner portion of the rectangular thin panel from a lower side. At each corner portion, stacking the corner modules in a columnar shape in the vertical direction stacks a plurality of rectangular thin panels in the vertical direction. At this time, the vibration suppressing body has the thickness that is equal to or less than the distance between the support surfaces of the corner modules adjacent to one another in the vertical direction.
