<P>PROBLEM TO BE SOLVED: To extraordinarily improve vibration-proof of a driving motor 6 by integrating a radial direction retaining portion 51 which elastically retains a side surface portion of the driving motor 6 accommodated and retained in a motor accommodation hole 36 of a motor housing 9 in a diametrical direction with a thrust direction retaining portion 52 which elastically retains an edge surface portion of the driving motor 6 in an axial direction. <P>SOLUTION: Vibration of the driving motor 6 in the radial direction is attenuated by the radial direction retaining portion 51 and vibration in the thrust direction of the driving motor 6 is attenuated by the thrust direction retaining portion 52 by constituting one vibration-proof spring 7 by integrating the radial direction retaining portion 51 with the thrust direction retaining portion 52 even when the motor housing 9 vibrates in both the radial direction and the thrust direction of the driving motor 6, thus extraordinarily improving the vibration proof of the driving motor 6 without causing an increase in the number of parts or man-hour of assembly. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
