description A magnetic disk device includes a plurality of disk-shaped magnetic disks (30), a spacer (80), a hub (90), a clamp (70), and a fastening member (72). The magnetic disk (30) has a through-hole in the center thereof. The spacer (80) has a through-hole in the center portion thereof, and is disposed between the magnetic disks (30). The hub (90) is inserted into the through holes of the magnetic disk (30) and the spacer (80). The clamp (70) presses and holds the magnetic disk (30) and the spacer (80). The fastening member (72) fastens the clip (70) to the hub (90). The clip (70) is fastened to the hub (90) by a fastening member (72) at a torque of 5-45 cN * m (inclusive). 磁盘装置包括圆盘形状的多个磁盘(30)、间隔件(80)、轮毂(90)、夹持件(70)、以及紧固构件(72)。磁盘(30)在中央部具有贯通孔。间隔件(80)在中央部具有贯通孔，并被配置在磁盘(30)之间。轮毂(90)被插入到磁盘(30)及间隔件(80)的贯通孔中。夹持件(70)对磁盘(30)及间隔件(80)进行按压保持。紧固构件(72)将夹持件(70)紧固于轮毂(90)。夹持件(70)由紧固构件(72)以5cN·m以上45cN·m以下的扭矩紧固于轮毂(90)。
