<P>PROBLEM TO BE SOLVED: To prevent vibration and noise of an electric motor by improving mounting rigidity generated between the electric motor part and a driving force transmitting part. <P>SOLUTION: There is provided a motor cylinder device in an electric brake actuator that generates brake fluid pressure based on an electric signal corresponding to brake operation. The motor cylinder device includes: an electric motor part 72 having a motor casing 72a in which the electric motor is housed and a base part 72b; and the driving force transmitting part 73 to which the drive of the electric motor is transmitted. The base part 72b is made of a resin, is connected to the motor casing 72a and is in contact with the driving force transmitting part 73. The motor cylinder device further includes a backlash preventing means such as protrusions and shims, between the base part 72b and driving force transmitting part 73. <P>COPYRIGHT: (C)2013,JPO&INPIT |
