A metal hub of a magnetic disk is attracted to a hub stand formed of a resin magnet, and a drive pin attached to the hub stand is engaged with an engagement hole formed in the metal hub, In a magnetic disk rotation drive device that rotationally drives a magnetic disk by preventing a drive pin from falling backward in the rotational direction of the hub base with a stopper, the stopper is a metal plate that is fixedly held on the hub base made of the resin magnet. A magnetic disk rotation drive device, characterized in that the drive pin faces the top of the drive pin so as to be able to come into contact with it. 2. The magnetic disk rotation drive device according to claim 1, wherein the stopper has an upper corner portion on the drive pin side protruding toward the drive pin side.
