A casing (10) for a disk player includes a housing (12), a lid (14) movable with respect to said housing between an open position and a closed position, and a resilient member (64). The housing houses a disk playing mechanism of said disk player, and defines two cavities (620, 622) and a buffer (624). The lid has a supporting member (60) being extendable into a first one of the cavities and being engageable with said buffer so as to buffer movement of said lid with respect to said housing. The resilient member is installed in a second one of the cavities, so as to resiliently provide movement of said lid with respect to said housing.
