PROBLEM TO BE SOLVED: To avoid abnormal noises produced during the rotation of a vibration generating motor. SOLUTION: An attachment seat 10 is provided on the housing of a computer game controller. A DC motor 11 with a weight 20 fixed to its motor shaft 13 is fixed to the attachment seat 10. When the DC motor 11 rotates, the weight 20 also rotates synchronously and gives a vibration to the DC motor 11. By the attachment of the weight 20, the total weight of an armature 15, etc., including the weight 20 exceeds the attractive force of a magnet 14 in the DC motor 11 and the motor shaft 13 tends to move vertically when the DC motor 11 rotates. However, by attaching a permanent magnet 22 to the weight 20, the weight 20 is attracted toward the casing 12 side of the DC motor 11, thereby avoiding the vertical movement of the motor shaft 13 and abnormal noises produced by the vertical movement. |
