In order to improve durability and reliability as well as supporting a gap between both side structures which do relative motion by being connected to a rotary shaft, a variable disk apparatus comprises a base disk having a first hole where the rotary shaft penetrates in a central portion, and having a guide groove portion along the circumference on a side in order to support the gap between facing sides of a first structure and a second structure by being inserted between the first and second structures which do relative motion by being connected to be rotatable by the rotary shaft; a guide disk having a second hole where the rotary shaft penetrates in the central portion, and having a guide protrusion, which is inserted into the guide groove portion, protruding from a facing side against one side of the base disk; a pressure element made of an elastic member to provide expansion by being installed between the guide groove portion and the guide protrusion; and a cover member installed on an upper side of the guide protrusion to be inserted inside the guide groove portion. |
