Claims

[Scope of utility model registration request]

By arranging the drive gear, the driven gear, and the intermediate gear so that their rotation axes are parallel to each other, and moving the intermediate gear in a direction perpendicular to the direction of the rotation axis during the mode switching operation, the drive gear, the driven gear, and the intermediate gear are In a rotational driving force transmission mechanism in which the rotational driving force of the driving gear is transmitted to the driven gear by meshing with both of the driving gear from the sides, the intermediate gear is connected to the first gear and the driven gear which mesh with the driving gear. The meshing second gear is coaxially and rotationally connected to each other in a two-stage configuration, and the modules of the three first gears and the second gear are different from each other. A rotational driving force transmission mechanism for a magnetic recording/reproducing device, characterized in that the second gear meshes with the driven gear after meshing with the driving gear.
