A stay housable type motor driven mirror to be attached, for example, to a car body has a drive gear rotatably driven by a drive apparatus, a clutch gear adapted to fit idlingly onto the support shaft and engage with the drive gear, a clutch holder fitted onto the support shaft beneath the clutch gear in order to rotate the support shaft by its rotation, a clutch mechanism having a concave face and a convex face, each so formed on a lower face of the clutch gear and an upper face of the clutch holder as to engage with each other, and a spring pressing the clutch gear to make the concave face and the convex face of the clutch mechanism engaged with each other. Consequently, it is possible to install the clutch mechanism at a side of follower of a large diameter gear and to increase a design allowance of clutch holding torque. In addition, a height of a bracket case is made shorten, design flexibility of stay attachment to the car body. Increasing an interior space of the bracket case increases design allowance of size and arrangement of the constitutional parts of the mirror simplifying the attachment.
