Patent number: 8938839Abstract: An elastic ring is disposed between a grip case and a trunk which is formed on an inner case of a body case to which a toothbrush head is mounted. As a result, the vibration of a motor which is contained in a motor accommodation portion of the inner case is less likely to be transmitted to the grip case because of the elastic ring, and is transmitted to the toothbrush head side in a concentrated manner. Also, the tooth cleaning performance is increased, and vibration to the hand which grips the grip case is reduced to enable the user to comfortably brush the teeth.Type: GrantFiled: December 15, 2010Date of Patent: January 27, 2015Assignee: Panasonic CorporationInventors: Tadanobu Kitagawa, Yoshihiro Kitamura
