器を提供することを目的とする。However, in the electromagnetic relay, since the movable iron piece and the coil block must be temporarily fixed in advance to the base due to the structure, the robot relay or the like is used to assemble the electromagnetic relay. When the operation is automated, the movable iron piece and the coil block are displaced from each other and cannot be reliably assembled. For this reason, the assembling operation is a manual operation. However, this has a problem in that the operation efficiency is poor, and the mounting position of the hinge spring varies, so that it must be adjusted in a later process. In view of the above problems, the present invention can be automatically assembled,
Moreover, an object of the present invention is to provide an electromagnetic relay capable of accurately positioning a hinge spring.
