The damper includes: a rotor and a rotor case that supports the rotor such that the rotor is rotatable around its axis. The rotor includes a cylindrical portion in which the support shaft is inserted, the cylindrical portion being held so as to be non-rotatable with respect to the support shaft. The rotor case is held by the sun visor body in a state where the rotor case is non-rotatable with respect to the sun visor body. ## Claims ### Claim 1 A vehicle sun visor comprising: a sun visor body; a support shaft mounted on a ceiling surface of a vehicle cabin and configured to support the sun visor body at a turning center position of the sun visor body such that the sun visor body is turnable between a storage position, at which the sun visor body is oriented along the ceiling surface of the vehicle cabin, and a use position, at which the sun visor body is able to block light; and a damper configured to apply braking force at the time when the sun visor body turns, wherein the damper includes: a rotor, the rotor being formed to have a larger diameter than the support shaft, and the rotor including a portion in which the support shaft is inserted, the portion being held so as to be non-rotatable with respect to the support shaft; and a rotor case that supports the rotor such that the rotor is rotatable around its axis, the rotor case being held by the sun visor body in a state where the rotor case is non-rotatable with respect to the sun visor body. ### Claim 2 (depends on 1) The vehicle sun visor according to claim 1, wherein: a projecting portion is formed on an inner periphery of a rotor body of the rotor, and a recess that fits the projecting portion is formed on an outer periphery of the support shaft. ### Claim 3 (depends on 1) The vehicle sun visor according to claim 1, wherein an inside of a rotor body of the rotor is formed into a rectangular shape and a small-diameter portion of the support shaft is formed into a rectangular columnar shape. ### Claim 4 (depends on 1) The vehicle sun visor according to claim 1, wherein a detent pin is inserted in a through hole that is continuous in a radial direction from a rotor body of the rotor to the support shaft. ### Claim 5 (depends on 1) The vehicle sun visor according to claim 1, wherein the support shaft extends through the rotor. ### Claim 6 (depends on 5) The vehicle sun visor according to claim 5, wherein: a projecting portion is formed on an inner periphery of a rotor body of the rotor, and a recess that fits the projecting portion is formed on an outer periphery of the support shaft. ### Claim 7 (depends on 5) The vehicle sun visor according to claim 5, wherein an inside of a rotor body of the rotor is formed into a rectangular shape and a small-diameter portion of the support shaft is formed into a rectangular columnar shape. ### Claim 8 (depends on 5) The vehicle sun visor according to claim 5, wherein a detent pin is inserted in a through hole that is continuous in a radial direction from a rotor body of the rotor to the support shaft. ### Claim 9 (depends on 1) The vehicle sun visor according to claim 1, wherein the support shaft is retained inside the rotor. ### Claim 10 (depends on 1) The vehicle sun visor according to claim 1, wherein the rotor case includes a flange portion that is formed at a lower-side of the rotor case, the flange portion being attached to the sun visor body. ### Claim 11 (depends on 1) The vehicle sun visor according to claim 1, wherein a portion of a rotor body of the rotor protrudes from an end of the rotor case in an axial direction. ### Claim 12 (depends on 1) The vehicle sun visor according to claim 1, wherein the sun visor body includes a bearing portion, the bearing portion having a leaf spring. ### Claim 13 (depends on 12) The vehicle sun visor according to claim 12, wherein the leaf spring is formed by a trapezoidal surrounding portion, a U-shaped spring portion, and a flat sheet portion. ### Claim 14 (depends on 1) The vehicle sun visor according to claim 1, wherein the portion of the rotor in which the support shaft is inserted has a cylindrical shape. ### Claim 15 (depends on 9) The vehicle sun visor according to claim 9, wherein: a projecting portion is formed on an inner periphery of a rotor body of the rotor, and a recess that fits the projecting portion is formed on an outer periphery of the support shaft. ### Claim 16 (depends on 9) The vehicle sun visor according to claim 9, wherein an inside of a rotor body of the rotor is formed into a rectangular shape and a small-diameter portion of the support shaft is formed into a rectangular columnar shape. ### Claim 17 (depends on 9) The vehicle sun visor according to claim 9, wherein a detent pin is inserted in a through hole that is continuous in a radial direction from a rotor body of the rotor to the support shaft.
