PROBLEM TO BE SOLVED: To provide a television lens apparatus capable of preventing dust and dirt from invading a cover via notched parts formed in a cover front surface. SOLUTION: The television lens apparatus includes: a lens cone where screw heads are protruded from the outer peripheral surface of the distal end part; and the cover having a cover body for storing the lens cone, and the cover front surface with an opening formed therein, where the distal end part of the lens cone with the cover body stored therein is inserted and projected. The apparatus is characterized by including: the notched parts in the cover front surface, where the screw heads pass through when the distal end part of the lens cone is inserted/projected to/from the opening; and block pieces, which are arranged on the outer peripheral surface of the lens cone, so as to block the notched parts from the inner part of the cover after the screw heads pass through the notched parts.
