Abstract
[Means to Solve Problem] A coil (68) is housed in a main body (70). An inner cylindrical portion (98a) is disposed inward of the coil (68). An armature (80) adapted to be attracted by the coil (68) is disposed, being spaced from the inner cylindrical portion (98a). A magnetic flux concentrating member (100) is disposed on the side of the coil (68) nearer to the armature (80), being spaced from the inner cylindrical portion (98a). The gap between the inner cylindrical portion (98a) and the magnetic flux concentrating member (100) is larger than the gap between the armature (80) and the inner cylindrical member (100).
