ABSTRACT:
A disk clamp mechanism includes a disk clamper (13), a main chassis (11), a disk clamper pushing member (14) and a resilient member (15). The disk clamper (13) has a contact surface (13a) contacting a disk, and a convex portion (13b) on a side opposite to the contact surface (13a). The main chassis (11) includes a frame body (11a) and a disk clamper holding member (11b) for holding the disk clamper (13). The disk clamper pushing member (14) has a pushing surface (14d) that pushes the convex portion (13b) of the disk clamper (13) toward the disk, and first and second end portions (14a, 14b) provided on both sides of the pushing surface (14d). The first end portion (14a) is swingably supported by the main chassis (11). The resilient member (15) urges the second end portion (14b) of the disk clamper pushing member (14) in the direction in which the pushing surface (14d) pushes the disk.
