A linear actuator includes a first tube, a second tube inserted into the first tube to be free to slide, a rod fixed at one end of the rod to the first tube, a rod guide provided on the other end of the rod so as to slide relative to the second tube, a plu...

Device has a yoke frame (4) that slides along an axis of displacement based on the effect of a magnetic field. The magnetic field is generated by a current conducted through a coil (1) and a magnetically permeable armature (5). The coil is displaced with r...

The object of the present invention is to improve the production efficiency by making its bonding process unnecessary to simplify the production process. The method of production comprises the step of integrally incorporating a magnetic material when the s...
