    摘要： 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. The number of a fixation tool inserted into the first plate-shaped portion to support the first arm is one or less.
