Abstract:
A CD is mounted in a CD carrier and is inserted and ejected to/from a recording and reproducing mechanism of an optical disk drive for commonly performing both of a reproduction of the CD and recording and reproduction of an MO cartridge. The CD carrier has a holder to enclose the CD and a CD turntable which is enclosed in a holder and mounts the CD to an upper portion and attaches a lower portion to a spindle motor of the recording and reproducing mechanism. The CD turntable has a first hub for attaching the CD to an upper portion of a disk on which the CD is mounted and a second hub for attaching a lower portion of the disk to a spindle motor of the recording and reproducing mechanism.
Abstract:
[Object] To provide a sealing device, which is capable of keeping a higher sealability even when a fluid pressure is not applied and even just after starting of application of the fluid pressure, and which is capable of reducing a sliding resistance while keeping a sealability during operation where the fluid pressure is always applied thereto.[Solving means] A sealing device (1) to be fitted in an annular groove (31) formed in one of a housing and a shaft as sliding members, respectively, where the housing has a shaft hole, and the shaft is inserted through the shaft hole and is configured to conduct a sliding movement relative to the housing, so that the sealing device seals an annular clearance (40) between the housing and the shaft from a fluid; wherein the sealing device comprises: a seal ring portion (11) having a sliding surface configured to be slid with the mating sliding member (20), and to seal the annular clearance (40) when a fluid pressure is applied to the sealing device; and a hermetic closure portion (12) for hermetically closing between the seal ring portion (11) and the annular groove (31) when the fluid pressure is not applied to the sealing device; and wherein the hermetic closure portion (12) is provided to be deformable in a direction for releasing the hermetically closed state between the seal ring portion (11) and the annular groove (31), by means of the fluid pressure when the fluid pressure is applied to the sealing device.
