ルミラー。[Claims for Utility Model Registration] A mirror body is tiltably supported with respect to a housing of a mirror drive unit, and one end of a plurality of screwed advancing and retracting rods provided in the drive unit is supported in a spherical manner relative to the mirror body. The electric remote control mirror is connected through a joint and has a structure in which the threaded advancement and retraction rods can be screwed through screw members that are screwed into each of the screwed advancement and retraction rods, and a male thread is provided on the outer periphery. A tubular advancing/retracting rod, a drive shaft that is slidably fitted with relative rotation locked to the center hole of the tubular advancing/retracting rod, and a male thread of the advancing/retracting rod provided with the above-mentioned male thread. A nut member having a female thread to be screwed together, a member provided on the outer circumferential side of the nut member and functioning as a male screw, and a drive cylinder having a female thread hole to be screwed into the member functioning as the male screw; The drive shaft is provided with a plurality of motors that rotate the drive shaft and the drive cylinder in forward and reverse directions, and a stopper means that limits the rotation angle of the mirror body, and the drive shaft is driven by the motor through a reduction gear train. The structure is such that the receiving gear of the final reduction stage of the reduction gear train and the drive shaft are equipped with a mechanism that causes slippage and interrupts transmission when a torque exceeding a predetermined value is applied, and the above-mentioned transmission As a means for blocking the above-mentioned retractable rod, a cut groove with a width dimension W is provided in the vertically divided shape, and the male thread provided on the retractable rod is divided into two, and the thread diameter is reduced. The drive shaft has a thickness dimension t≪
It has two parallel surfaces W and is loosely fitted into the cut groove, and the amount of fitting thread D between the male screw of the retractable rod and the female screw of the nut member satisfies D<W-t. Electric remote control mirror with one feature.
