In a vehicle door mirror device, a through hole of a case is penetrated by a support shaft so as to rotatably support the case on the support shaft. Lower ribs are formed in a protruding state at a peripheral face of the through hole, and protrusion leading end faces of the lower ribs are capable of contacting the support shaft. A gap dimension between the peripheral face of the through hole and the support shaft can accordingly be made small, thereby enabling rattling of the case with respect to the support shaft to be suppressed. Moreover, the contact surface area between the peripheral face of the through hole and the support shaft can be made small, thereby enabling an increase in sliding resistance between the peripheral face of the through hole and the support shaft to be suppressed.
