PROBLEM TO BE SOLVED: To make a motor device thin and reduce an installation space by arranging winding made flat by shifting it in the peripheral direction and a plate member forming a magnetic path in a rotary member. SOLUTION: Four fanlike permanent magnets 14 are arranged at an equal interval inside a motor device 100 centered on a shaft 19, and a winding 22 having a flat coreless shape in the peripheral direction is arranged in an upper part of the permanent magnet 14. Moreover, a doughnut-shaped plate member (iron plate) 23 for ensuring a magnetic path of the permanent magnet 14 is provided in an upper part of the winding 22. Furthermore, a rotary member (pulley) 6 provided with a groove 25 for winding a wire 15 covers it from above on the same axis as the shaft 19. The pulley 6 is made of a resin such as POM (polyacetal) having a good slide property, includes the iron plate 23 which is a rotary part of the motor and the winding 22, and is integrally formed by a resin. |
