In an electromagnetic relay formed with an engagement hole for engaging a drive part, the support hole is formed in a substantially T-shape, and a through hole for preventing sinkage is formed on the same surface as the engagement hole. The purpose of the present invention is to achieve the above object by adopting a configuration in which a.
［実施例］
以下本考案の一実施例を第１図に基づいて説明
する。なお、上述した従来例と同様な構成は同符
号を用いるものとする。[Example] An example of the present invention will be described below based on FIG. Note that configurations similar to those of the above-described conventional example are designated by the same reference numerals.
第１図は本実施例に係る電磁リレーの設置部の
斜視図を示す。 FIG. 1 shows a perspective view of an installation part of an electromagnetic relay according to this embodiment.
設置部１は、Ｌ字形の形状をなし、端子用貫通
孔８を形成した舌片部４の一端に支持部３を立設
してなる。 The installation part 1 has an L-shape, and is made up of a support part 3 erected at one end of a tongue part 4 in which a terminal through-hole 8 is formed.
この支持部３の両端側には、固定接点ばね２を
支持するための支持用穴５，５を形成してあり、

孔６を形成してある。 Support holes 5, 5 for supporting the fixed contact spring 2 are formed at both ends of the support portion 3.
The support hole 5 is formed into a substantially T-shape. Also,
An engagement hole 7 for engaging the tip 14 of the yoke 11 described above is formed on the lower end side of the support portion 3, and a through hole 6 for preventing sinkage is formed on the same surface as the engagement hole 7. It has been formed.
即ち、上記支持用穴５をＴ字型にすることによ
