Claims (1)

[Scope of utility model registration request] The fixed part, which is a hollow housing, is connected to the stationary side of the machine tool so that it can be engaged and disengaged, and the first half with a center hole is rotatably inserted into the hollow housing, and the second half is connected to the main shaft of the machine tool. A rotating part to be mounted, and a tool attachment that is inserted into the center hole of the rotating part, is rotatable relative to the fixed part and the rotating part, is connected to the rotating part via a planetary speed increasing mechanism, and has a tool attached to the tip part. A labyrinth seal is provided at the outer end area of the relative rotation area between the fixed part, rotating part, and tool mounting part,
A tool adapter with a built-in planetary speed increase mechanism in which a V-shaped cross-section ring made of an elastic material with a lip is fitted adjacent to the inside of a labyrinth seal.
