Abstract
An internal structure of an apparatus using a loading motor such as a video cassette recorder or a camcoder and, more particularly, a loading worm guide apparatus is provided and includes a bracket structure for preventing a worm gear, which has received an axial thrust while being driven by a loading motor, from being disengaged. A conventional loading worm guide apparatus cannot adaptively adjust to the change of the state of a loading worm since a bracket is fixed to a main chassis. In contrast, the present loading worm guide apparatus interposes an elastic member between a bracket and a main chassis and can adjust a distance between the loading worm and the bracket by tightening or loosening a screw.
