The pivoting portion 32 includes a first side 33 and a second side 35 opposite to each other. The pivoting portion 32 is provided with a circular boring hole 34 and a fixing hole 36 extending through the first side surface 33 and the second side surface 35 of the first sheet 33 and the first sheet number A0101. The first side surface 33 protrudes from the three protrusions 332 surrounding the boring hole 34. The second side surface 35 defines three recessed areas 352 to reduce the contact area of the rotating member 30 with the crown portion 16 of the rotating shaft 10. Each recessed area 352 does not penetrate the first side 33 and corresponds to the corresponding stud 332. A wedge-shaped abutting block 354 is formed at the edge of the second side surface 35. One end of the abutting block 354 extends to the second side surface 35 with a smooth transition surface. [0011] The first interference member 40 is provided with a circular through hole 42 such that the first interference member 40 is rotatably sleeved on the shaft 14. The first interference member 40 includes a mating face 45 that faces away from the first side 33 of the rotating member 30. The mating surface 45 is recessed to form a first recess 44 and a second recess 46 surrounding the through hole 42. The first recess 44 is adjacent to the edge of the through hole 42. The second recess 46 is opposite the first recess 44 and is adjacent to the edge of the first interference member 40. The edge of the first thousand member 40 is axially extended toward the first end face 45. [0012] The second interference member 50 is substantially disk-shaped, and a non-circular mounting hole 51 corresponding to the sectional shape of the shaft 14 of the rotating shaft 10 is disposed in the middle portion, so that the second interference member 50 can be The shaft 14 is fixedly sleeved. A first convex portion 54 and a second convex portion 56 surrounding the mounting hole 51 are protruded from an end surface of the second interference member 50 opposite to the mating surface 45 of the first interference member 40.
