To provide a scroll compressor with a rotation prevention mechanism absorbing processing errors and assembling errors of a drive shaft, a crank pin and the like and surely preventing leakage of a lubricant from insides of support holes.
According to the invention, in the rotation prevention mechanism 41, a first shaft portion 45a of the crank pin 45 is rotatably supported in the first support hole 43 of a movable side scroll member 28 via a first bearing 47 and a second shaft portion 45b is rotatably supported in the second support hole 44 in an end surface 12a of a center housing 12 via a second bearing 48. A cylindrical member 55 is received in the first support hole 43. The first shaft portion 45a, the first bearing 47 and a ring-shaped rubber seal member 57 are disposed in the cylindrical member 55. An elastic member 49 in the first support hole 43 is disposed between an inner peripheral surface of the first support hole 43 and an outer peripheral surface of the cylindrical member 55, or radially outside of the cylindrical member 55 with respect to the cylindrical member 55.
