<p>PURPOSE:To provide the title electromagnet device capable of abating the collision noise of an armature as well as avoiding the defects such as the decrease in the magnetic attraction or the displacement of the armature. CONSTITUTION:Within the title electromagnet device provided with a yoke 1, an electromagnetic coil 2, an armature 3 and a velocity buffer member 5 abutting a specific term before the armature reaches a first or second position to receive a load while not receiving the load when reaching the first or second position, the velocity buffer member 5 having pole pieces 5b comprising a magnetic material is formed while a permanent magnet 4 for generating the load is arranged on the armature 3. Furthermore, a recession 1d for pole pieces to make the pole contact state between the yoke 1 and the armature 3 not to be affected by the pole piece 5a of the velocity buffer member 5 is formed in the central leg piece 1a of the yoke 1.</p> |
