To provide an electric retractable vehicle periphery viewing device, that can improve fuel efficiency due to air resistance and that can prevent a damage or the like in the event of a collision of an obstacle when the device is in use, the electric retractable vehicle periphery viewing device of the present invention includes a base (), a shaft () and a viewing assembly (). The viewing assembly () includes a housing (U), (D), a viewing unit (), and an electric retracting unit (). The electric retracting unit () includes a casing (U), (D), a motor (M), a speed reduction mechanism (), a clutch mechanism (), and a rotational force transmission mechanism (). The motor (M), the speed reduction mechanism (), the clutch mechanism (), and the rotational force transmission mechanism () are arranged in a direction intersecting with an axial direction of the shaft (). 1. An electric retractable vehicle periphery viewing device , comprising:a base fixed to a vehicle body;a shaft fixed to the base; anda viewing assembly rotatably attached to the shaft; a housing;', 'a viewing unit mounted in the housing; and', 'an electric retracting unit housed in the housing and configured to rotate the viewing assembly,, 'wherein the viewing assembly includes the shaft;', 'a casing rotatably attached to the shaft and fixed to the housing;', 'a motor and a speed reduction mechanism that are attached to the casing;', 'a clutch mechanism attached to the casing, the clutch mechanism being in a connected state when the electric retractable vehicle periphery viewing device is in a normal case, to transmit a rotational force of the motor via the speed reduction mechanism to the casing, the clutch mechanism being in a disconnected state when force greater than the rotational force transmitted from the motor is applied to the viewing assembly, to rotate the viewing assembly without transmitting, to the speed reduction mechanism, the force greater than rotational force transmitted from the motor; and', ...
