ABSTRACT:
The present invention relates to a rotatively driven type electric component wherein a slider is moved linearly by rotation of a screw. The rotatively driven type electric component with housings, a drive shaft held by the housings and provided with a screw portion, an insulating substrate held by the housings and having electrically conductive patterns, a slider which comes into sliding contact with the electrically conductive patterns, a movable block which holds the slider, and a plate spring disposed between the movable block and the drive shaft and locked to the movable block, the plate spring having a protuberance, the protuberance of the plate spring being brought into elastic contact with the screw portion of the drive shaft so that the movable block is moved with rotation of the drive shaft.
