Summary:To suppress reduction in magnetic efficiency of an electromagnet, in an electromagnetic relay.SOLUTION: An electromagnetic relay comprises a contact device, a drive device, and a coil terminal. The drive device includes a coil, a spool, a first yoke, and a second yoke. The coil is arranged in a first direction with respect to the contact device. The spool extends in an axial direction along the first direction, and the coil is wound around the spool. The first yoke is arranged in a first direction with respect to the coil. The second yoke is arranged around the coil and connected to the first yoke. The second yoke includes a first side portion, a second side portion, a center portion, and a notch for drawing out the coil terminal. The first side portion extends in the axial direction and abuts on the first yoke. The second side portion is arranged in such a way as be opposed to the first side portion and abuts on the first yoke. The center portion is arranged between the contact device and the spool and connects between the first side portion and the second side portion. The notch is formed at a position closer to the contact device than a portion abutting on the first yoke in the first side portion.SELECTED DRAWING: Figure 3 【課題】電磁継電器において、電磁石の磁気効率の低下を抑制する。【解決手段】電磁継電器は、接点装置と、駆動装置と、コイル端子とを備える。駆動装置は、コイルと、スプールと、第1ヨークと、第2ヨークとを含む。コイルは、接点装置に対して第1方向に配置される。スプールは、第1方向に沿う軸線方向に延びコイルが巻き付けられる。第1ヨークは、コイルに対して第1方向に配置される。第2ヨークは、コイルの周囲に配置され、第1ヨークに接続される。第2ヨークは、第1側部と、第2側部と、中央部と、コイル端子を引き出すための切り欠きと、を含む。第1側部は、軸線方向に延び第1ヨークに当接する。第2側部は、第1側部に対向して配置され第1ヨークに当接する。中央部は、接点装置とスプールの間に配置され第1側部と第2側部とを接続する。切り欠きは、第1側部において第1ヨークに当接する部分よりも接点装置に近い位置に形成されている。【選択図】図3
