摘要： An electromagnetic relay includes a spool, a coil wound on the spool, an armature inserted in the through hole of the spool, a yoke fixed to the spool by fitting, hinge springs, a movable spring, a hinge spring fixing portion, an attaching/fixing portion, and at least one terminal. The armature operates upon excitation of the coil. The yoke has first and second opposing upright portions. One end of the armature is in contact with an end face of the first upright portion, and the other end thereof opposes the end face of the second upright portion. The hinge springs set the armature at a predetermined angle with respect to the yoke, and urge one end of the armature against the end face of the first upright portion to ensure magnetic connection. The movable spring has a movable contact and extends from one side of the hinge springs. The movable spring is connected to the armature. The hinge spring fixing portion extends from the ends side of the hinge springs that are not connected to the movable spring, to support them and the movable spring. The attaching/fixing portion attaches and fixes the hinge spring fixing portion on the first upright portion by a single operation. The terminal member is fixed to one end portion of the spool by press fitting and has a stationary contact adjacent to the movable contact.
