    摘要: In a friction drive actuator 1 according to the invention, a rotor 2 and a stator 4 are held in contact at a plurality of positions by a plurality of vibrators 3, and at least one of the vibrators 3 vibrates to rotate the rotor 2 relative to the stator 4. Accordingly, the rotor 2 is supported without using a bearing and, hence, the rotor 2 can be more easily elastically deformed as compared with the case where the rotor 2 and the stator 4 are held in contact over the entire circumference. Therefore, a frictional force between the stator 4 and the rotor can be stabilized.

    摘要: To provide a backlight having a positioning member that can prevent from coming off from metal frame and damaging a display panel even when used in a harsh environment such as undergoing sharp temperature changes.A backlight unit comprises a light guiding module having a light source and a light guide plate; a resin frame having a recess formed by side walls and bottom surface thereof, and housing the light guiding module; and a metal frame fitted with the resin frame, having an opening in an upper surface thereof and the opening being located above the recess of the resin frame, and allowing to pass light from the light guiding module therethrough. The resin frame has a protrusion on the top surface of one of the side walls of the recess. The metal frame has a notch on the upper surface thereof so that the protrusion passes therethrough. The opening allows the light from the light guiding module to pass therethrough.
