Patent number: 6948464Abstract: The variable valve timing controller has an electric motor which rotates a phase converter. When the electric motor is locked for some reason, the over-load more than the predetermined value is applied to a motor shaft and the phase converter. In such a case, a pin connecting the motor shaft with the phase converter is sheared at a notch. Thus, a cam shaft and the phase converter were not locked, and breakage of a motor housing is prevented.Type: GrantFiled: March 5, 2004Date of Patent: September 27, 2005Assignees: Denso Corporation, Asmo Co., Ltd.Inventors: Shinsuke Ido, Akira Tsunoda, Toshihiro Matsuura, Yoshiyuki Takabe
