发明名称 Throttle valve opening degree sensor
摘要 The present invention provides a throttle valve opening degree sensor for detecting the opening degree of a throttle valve used for an internal combustion engine wherein a rotor shaft capable of interlocking with a throttle valve has a cylindrical covering portion having an outer circumferential cylindrical body at the outer end, the cylindrical covering portion covering the outer end of the bearing portion exposed to the base portion of the housing and having an elastic engaging portion having cross-like splitted grooves at the top end and a square outer periphery, and the rotor has a square engaging hole capable of fitting the elastic engaging portion, the elastic engaging portion being fitted to and elastically abutted against the engaging hole thereby securing the rotor to the rotor shaft. According to the throttle valve opening degree sensor, it can prevent the deviation of the rotor from the center and enhance the accuracy for the attaching position, and provide water proofness and dust proofness for the outer end of the rotor shaft and the bearing portion.
