摘要： PURPOSE: To positively retain a motor by enabling a hole part without any opening at the surroundings being provided at a rising part raised from a base part to be engaged to a projecting part around an output shaft located in front of the enclosure of a motor. CONSTITUTION: Arm parts 32 and 33 are extended from a base part 31 so that they are along the outer periphery of an enclosure 2 of a motor 1. A rising part 34 is bent upward at the front edge side of a base part 31. A hole part 35 is opened with a diameter which nearly matches the outer diameter of a projecting part 3 of the motor 1 nearly at the center of the rising part 34. A leg part 36 is located at the front side of the base part 31 and is bent downward while it is partially cut. A leg part 37 is located at the rear side of the base part 31 and is bent and formed downward. A nib part 38 is bent toward the inside from the arm parts 32 and 33 and presses the rear edge part of the motor 1 to prevent pull-out toward the rear. An engagement part 39 is engaged to a recessed part provided at the rear edge of the enclosure 2 of the motor 1.

摘要： PROBLEM TO BE SOLVED: To fix a vibrator without bending a rotating shaft in the case of fixing the vibrator to the rotating shaft by caulking the shaft with an attaching member. SOLUTION: In a method by which a block-like vibrator 4 having a shaft fixing surface 5 is eccentrically fixed to the rotating shaft 3 of a vibration generating motor 1, the vibrator 4 is fixed to the shaft 3 by pushing the shaft 3 in a shaft inserting groove 6 having an opened end section 8 protruded inward while the end section 8 is temporarily widened by press-fitting the shaft 3 in the groove 6 from the upside of the shaft fixing surface 5.
