Abstract

PURPOSE:To increase the stroke by moving the floating coil itself with the ferromagnetic bar part of a shaft member being attracted. CONSTITUTION:The shaft member 1, which is constituted by butting the ends of the ferromagnetic bar 1a and the nonferromagnetic bar 1b, is pierced through a casing 2 so that said member 1 can be slidden. To one end of the casing 2, is fixed a fixed coil 3 through which the shaft member 1 is pierced so that it can be slidden. A stopping member 4 is fixed on the side of the ferromagnetic body of the shaft member 11. A floating coil 5 nonexpandable compressible elastic body 6, through which the shaft member 1 is pierced so that it can be slidden freely, are provided between the fixed coil 3 and the stopping member 4. When the current is conducted through coils 3 and 5, the attracting force is generated between the coils 3 and 5, and between the ferromagnetic bar 1a and the coils 3 and 5, and the shaft member 1 moves toward the side of the fixed coil 3.
