動作特性の安定したリレーを提供するにある。In the relay described in the conventional example, the movable contact spring 21 is directly fixed to the armature 20 by a method such as welding, and the number of parts can be reduced because there is no need for a special connecting member to connect the two together. However, amateur 2
0 is only supported by a yoke 25 which also serves as a common terminal by a protrusion 20a on the lower center surface, and the amateur 20
The mounting positioning and swinging support in the left-right and front-back directions are performed by a pair of support spring parts 21a and 2 that extend in a meandering direction in the swing axis direction.
1a is welded and fixed to the yoke 25, so the support spring portion 2 for the yoke 25 is
ia, 21a welding position variations, both support spring parts 2
Due to variations in the welding conditions between 1a and 21a, there was a problem in that the swinging support state of the armature 20 varied and stable operating characteristics could not be obtained.6 The present invention focuses on the above problem and aims to improve it. The purpose of this is to provide stable support for the can.
The aim is to provide a relay with stable operating characteristics.
