Document Type and Number:
WIPO Patent Application WO/2005/027317
Kind Code:
A1
Abstract:
[PROBLEMS] To realize high reliability and long term stabilized power supply (long lifetime) in connection between a power supply terminal and a power supply land on a circuit board. [MEANS FOR SOLVING PROBLEMS] The vibration generating motor comprises a vibration generating mechanism where a weight is fixed to a rotary shaft, a housing case containing at least a part of the vibration generating mechanism, and a pair of power supply terminals projecting from the housing case and in resiliently contact for electrical connection with a power supply land on a power supply side circuit board mounted in a portable apparatus case and supplying power to the vibration generating motor, wherein each of the fulcrum and the acting point of a power supply terminal movable portion movable in the direction to be in contact with the power supply land of the power supply terminal is provided along a plane that includes the gravity center of vibration operation of the vibration generating motor and is substantially perpendicular to a rotating shaft of the weight.
