徴とする歯科用ライトアーム。 A dental lamp comprising a support arm 1 equipped with a horizontal rotation and/or vertical swing mechanism, a hanger arm 2 connected to the tip of the support arm 1, and a lamp head 3 attached to the tip of the hanger arm 2. In the light arm, hanger arm 2
, a cylindrical cover 4 connected to the tip of the support arm 1, and a rotating support shaft 5 which is inserted into the cover 4 so as to be rotatable and has the lamp head 3 attached to the tip.
, a connecting member 6 that connects the rotational support shaft 5 and the cover 4 in a manner that allows the rotation of the rotational support shaft 5 but prevents the rotational support shaft 5 from coming off from the cover 4; and an inner surface of the cover 4. A sleeve 7 is interposed between the outer periphery of the rotating support shaft 5 so as to be in tapered sliding contact with either surface of the sleeve 7, and the sleeve 7 is elastically biased, and due to the pressure reaction force of the tapered surface due to the biasing elasticity. A dental light arm comprising a rotating stationary means 8 that generates a frictional resistance holding force between a cover 4 and a rotating support shaft 5.
