a visor body that includes a first component member and a second component member that are stacked in a thickness direction;

a support shaft that is inserted into the visor body to support the visor body such that the visor body is turnable between a service position and a storage position;

a case that supports the support shaft such that the support shaft is turnable in the visor body, the case being slidably fitted to the visor body;

a clip that is provided in the case and that urges the visor body toward the storage position by urging the support shaft; and

a guide rail that is formed integrally with the first component member to prevent the case from falling in the thickness direction with respect to the first component member and to support the case such that the case is slidable with respect to the first component member,

wherein the guide rail includes a first rail and a second rail, the first rail and the second rail both including protruding portions that protrude toward each other along an up-down direction of the vehicle sun visor with the case in between,

the protruding portions of the first rail and the second rail cooperate to prevent the case from falling off in a thickness direction with respect to the first component member,

the case includes an engagement portion protrusion that is sandwiched by a first portion of the first component member and the protruding portion of the first rail, in the thickness direction,

the case also includes a lower rail projection portion that is sandwiched by a second portion of the first component member and the protruding portion of the second rail, in the thickness direction, and

the engagement portion protrusion and the lower rail projection portion are disposed on opposite sides of the case in the up-down direction.
