To provide a magnetic driver, averting the number of components from increasing, and the configuration from becoming complex, miniaturizing the outer shape, and enabling a yoke to be firmly positioned with respect to a rotor magnet.
The magnetic driver comprises: a rotor magnet 1; a coil bobbin 4 around which a coil is wound and which has a through-hole in a central part; a yoke 5, 3 including a straight portion to be inserted in the through-hole and an arc-shaped portion connected to the tip end of the straight portion; a support member 2 rotatably supporting the rotor magnet; and a thrust receiving member 6 including an engagement part engaged with the supporting member, and having one surface regulating one end of the rotor magnet in a thrust direction and another surface on which the coil bobbin is placed, and which is held between the arc-shaped portion of the yoke and the coil bobbin. The yoke is assembled as an integrated yoke, by inserting the straight portion in the through-hole of the coil bobbin, and affixing the straight portion to the arc-shaped portion which is a separate body.
