Abstract

The invention provides a chuck device, comprising: a central housing, the inner circumferential surface of the chuck is fixed on the central housing; a pawl formed in the central housing and moving to the internal side of the central housing to support the inner circumferential surface of the chuck in an elastic way during installation of the chuck, when the external force is made to make the pawl deform, the lower end of the pawl is formed to be spaced apart from a rotary component to provide an elastic limiting spacing from the rotary component, making the pawl deform in the elastic deforming limiting range of the pawl, and the rotary member rotates together with the central housing.

Description

[0001] This application claims priority to Korean Patent Application No. 10-2010-0040331 filed with the Korean Intellectual Property Office on Apr. 29, 2010, the disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a chuck device and a motor device using the same, more particularly, to a chuck device capable of deforming within the range of elastic deformation while preventing jaws from being excessively bent due to an external force and using the same motor device. Background technique [0003] Generally, a spindle motor installed in a disk drive apparatus rotates the disk so that an optical pickup can read data recorded on the disk. [0004] The platter is held in place by a chuck device that rotates with the spindle motor. In this configuration, loading and unloading of discs is repeated on the chuck device. [0005] The disk is mounted by mounting the inner peripheral surface of the disk to the outer periphe...
