Abstract
An optical disc device comprises a disc clamper. The disc clamper is provided with: a first member provided with a first circular disc, and with a plurality of upstanding pieces formed with predetermined spaces therebetween along a circle concentric to the first circular disc, the upstanding pieces having an engaging claw at the distal end thereof; and a second member provided with a second circular disc in which are formed a plurality of through-holes into which the plurality of upstanding pieces are inserted, and with a plurality of peripheral walls formed with predetermined spaces therebetween along a circle concentric to the second circular disc. Rotation in a state where the upstanding pieces have been inserted into the through-holes through the spaces between the peripheral walls causes the engaging claws to engage the peripheral walls.
