Реферат: Disclosed are a hollow component, a method for manufacturing a hollow component, and a device for manufacturing a hollow component. The method for manufacturing a hollow component according to an embodiment of the disclosure includes a first operation of molding a first injection-molded component, a second operation of molding a second injection-molded component, a third operation of causing the first injection-molded component and the second injection-molded component to face each other, a fourth operation of approaching the first injection-molded component and the second injection-molded component, and a fifth operation of coupling the first injection-molded component and the second injection-molded component. A fastening boss of the first injection-molded component is press-fitted into a fastening hole of the second injection-molded component in the fifth operation. Therefore, the fixation between the first injection-molded component and the second injection-molded component may be achieved without additional injection, and breakage and damage of the fastening boss and the fastening hole may be prevented.
