摘要： An example of an optical disc apparatus includes a top case and a bottom case. The top case includes a tab extending downward from one end of the top case. The tab includes a protrusion protruding inward. The bottom case includes a lower-side folded portion formed by folding inward an upper end of one side surface of the bottom case. The lower-side folded portion includes a cantilever spring. The cantilever spring includes a spring portion extending in a vertical direction and a curved portion formed by folding inward an upper part of the spring portion. The protrusion comes into contact with the curved portion when the top case is being affixed to the bottom case and is in contact with the spring portion under a state where the top case is affixed to the bottom case.
