Electromagnetic relay

An electromagnetic relay comprising:

• a sealed housing;
• a fixed contact arranged in the sealed housing;
• a movable element having a movable contact configured to be brought into contact with and separated from the fixed contact in the sealed housing;
• a shaft holding the movable element and provided in such a manner as to be capable of advancing and retreating in an axial direction relative to the sealed housing;
• a movable core fixed to the shaft;
• a fixed core fixed to the sealed housing;
• a return spring urging the movable contact in a direction away from the fixed contact;
• an electromagnetic coil configured to generate, when energized, magnetic attraction between the fixed core and the movable core;
• and
• a sleeve hermetically sealing the return spring and the movable core therein and fixed directly or indirectly to the fixed core,
• wherein
• the shaft is slidably inserted in a through-hole formed in the fixed core,
• the sleeve has a support part supporting the movable core so as to define a position of the movable core relative to the fixed core when the magnetic attraction does not act;
• and
• at a front end of the sleeve, there is formed a position adjustment part for adjusting a positional relationship between the fixed core and the support part during the direct or indirect fixing of the sleeve to the fixed core.
