<p>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).</p> |
