<p><P>PROBLEM TO BE SOLVED: To provide an electric pump enabling a rotor to be peeled off a pump case while suppressing an increase in size. <P>SOLUTION: A drive shaft 31 is inserted into the motor rotor 43 of the electric motor rotatably relative to the motor rotor 43. A first hammer part 45 and a second hammer part 55 moving along the rotating direction of the motor rotor 43 when the motor rotor 43 is rotated are installed at the rear end of the motor rotor 43 along the axial direction of the drive shaft 31. An impact part 50a on which the first and second hammer parts 45, 55 are impacted is projectedly formed on the drive shaft 31 rotatably integral with the drive shaft 31. Moving spaces 46 so allowing the first and second hammer parts 45, 55 as to directly impact them against the impact part 50a are formed between the first and second hammer parts 45, 55 and the impact part 50a along the rotating direction of the motor rotor 43. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
