A height adjusting device for a lamp includes a main body( 100 ) having a motor( 120 ), a casing( 160 ) mounted below the main body( 100 ), an upper terminal unit( 200 ) having upper contact terminals( 240 ) spaced apart from the main body( 100 ) in the casing( 160 ), a moving body( 400 ) moving vertically by a cable( 140 ) connected to the main body( 100 ) and having lower contact terminals( 420 ) corresponding to the terminals( 240 ), and a stopper( 300 ) mounted to the casing( 160 ) to elastically maintain its horizontal state. The moving body( 400 ) has a protrusion( 430 ) at its side to partially contact with the stopper( 300 ) so that the moving body( 400 ) is hooked at a certain height by the stopper( 300 ) when the protrusion( 430 ) ascends over the stopper( 300 ) and then descends, while the moving body( 400 ) may move downward when the side ascends over the stopper( 300 ). |
