摘要： An electromagnetic device is provided with a coil bobbin (1) supporting an excitation coil (5) and a U-shaped movable iron piece (2) whose one side (2a) is inserted in and fixed to a hollow section (1a) of the coil bobbin (1) in a state where it is held between a pair of iron cores (3) and (4). A remaining side (2b) of the U-shaped movable iron piece (2) is inserted in a through-hole section (1c) of the coil bobbin (1) and has a resilient characteristic that it is spaced away from the one side (2a). The top surface of each of rising sections (3a) and (3b) of the iron cores (3) and (4) is configured by bending the end of each of the rising sections (3a) and (3b) and is located to be opposite to the top of the remaining side (2b) at a preset distance away.
