Device mounting mechanism and device mounting method for rack mount

A device mounting method for a rack mount that loads a device into an area within a plurality of columns constituting the rack mount, the device mounting method comprising:

• rotatably supporting one end and the other end of a mount bar having a length substantially equal to the width of the area surrounded by the columns, by mounters movable in the depth direction of the area;
• orienting the mount bar obliquely with respect to the depth direction within the area;
• attaching the device to the obliquely oriented mount bar along the mount bar;
• and
• rotating one end and the other end of the mount bar about shafts, wherein a rotation center of one of the shafts to which at least one of the one end and the other end of the mount bar is connected and which is movable in a direction connecting the shafts, while the one end and the other end of the mount bar are connected to each mounter, to move the device in the depth direction while reducing an inclination of the device with respect to a member to which the device is attached.
