摘要： To prevent deformation of a chassis due to an impact force in an optical disc apparatus, there is provided a tray for inserting/ejecting an optical disc into/from an apparatus body, with the chassis connected thereto through vibration proof materials in plural portions in a surface opposite a disc placing surface. The tray has projecting portions projecting in a chassis direction in positions facing the chassis in peripheral portions of the plural connecting portions. The projecting portion is located at a position higher than a tray plane with which the vibration proof material comes into contact, and lower than the surface of a chassis facing the tray. When the vibration proof material is compressed and deformed due to the impact force, the projecting portion comes into contact with the chassis facing surface, to reduce the amount of deformation of the vibration proof material and thereby prevent deformation of the chassis.
