PROBLEM TO BE SOLVED: To provide a mechanism capable of improving the assemblability of a mirror mechanism by facilitating the assembly of a mirror holding member holding a mirror into a mirror box, without reducing the strength of the mirror box.SOLUTION: A mirror mechanism 100 includes a mirror box 112, a mirror holding member 111 which is arranged in the mirror box 112, holds a mirror 110, and is supported by the mirror box 112 to be rotatable through a rotation shaft 111a, and a driving force transmission member 113 which transmits a driving force to the rotation shaft 111a. In the mirror box 112, a groove 112a with which the rotation shaft 111a is engaged in such a state that the axial end of the rotation shaft 111a is projected to the outside of the mirror box 112 is formed. A member to be driven 111b to which the driving force is transmitted from the driving force transmission member 113, to rotate the rotation shaft 111 engaged with the groove 112a is provided integrally with the end projected to the outside of the mirror box 112, of the rotation shaft 111a. |
