The plurality of piece-like support portions 43 are connected to the outer periphery of the cylindrical cylindrical slip 41. The disk portion 44 is connected to the cylindrical cylindrical slip 21 and covers the second circular mat member 30. The convex edge portion 45 is formed so as to surround the outer periphery of the convex edge portion 32 of the second circular mat member 30. The plurality of fitting portions 46 are formed on the inner peripheral surface of the convex edge portion 45. The protective edge 47 is formed so as to surround the outer peripheral surface of the outer edge 35 of the second circular mat member 30.

  The fitting portion 46 of the stretch film mounting member 40 is fitted with the fitting portion 34 of the second circular mat member 30 to suppress relative rotation.

  The stopper 50 is disposed in the cylindrical portion 13 of the main body 10 and suppresses separation between the stretch film attachment member 40 and the main body 10.

  Specifically, the stopper 50 has a cylindrical portion 51 and a contact portion 52. The cylindrical portion 51 is fitted into the circular through hole 14 of the main body 10. The abutting portion 52 blocks the cylindrical slip 41 of the stretch film attachment member 40.

  Due to the above-described structural features, the first circular mat member 20 and the second circular mat member 30 can be rotated relatively to make the operation smooth, and the worn first circular mat member 20 and the second circular mat are worn. Since the member 30 can be easily replaced, the service life of the main body 10 and the stretch film attachment member 40 can be extended.
