A disk drive to be mounted on a chassis has lateral sides further including lower edges. The lower edges provide a plurality of restraint flanges, a plurality of position stems, and a plurality of constraint parts. The chassis has a plurality of hooks, a plurality of guiding holes, a plurality of deflection arms. While in a lock-on state of the disk drive and the chassis after performing a slide-and-lock operation in between, the restraint flanges are nested inside the respective hooks, the position stems are located at respective anchoring ends of the respective guiding holes, and the constraint parts form interference relationship with the respective deflection arms.
