Title:
ULTRASONIC VIBRATION ROLLER BEAUTY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/117923
Kind Code:
A1
Abstract:
[Problem] To provide a structure which has excellent durability and which prevents contact failure between contact points due to friction when supplying power to an ultrasonic vibration element of a rotor. [Solution] A plurality of conductive bearings are arranged between a rotor and a handle which supports the rotor. An electrode which drives the ultrasonic vibration element and a high-frequency power source unit are electrically connected via the bearings. The electrodes are provided as a pair and connect to the high-frequency power source via the bearings which are electrically insulated from the electrodes. As a result, it is possible to resolve the conventional problem of contact failure caused by abrasion of contact points.
