<P>PROBLEM TO BE SOLVED: To provide a position detection device for suppressing the influence of detecting accuracy due to an external magnetic field. <P>SOLUTION: The position detection device 1 includes: a part 4a to be detected which rotates according to the rotation of a handle grip 3 installed in a handle bar 2; a detection part 5 for detecting the part 4a to be detected; and a case 7 in which the part 4a to be detected and the detection part 5 are stored. The part 4a to be detected is configured as a cylindrical body having magnetism, and the detection part 5 is configured as a magnetic detection part 5 for detecting the change of magnetism. The position detection device 1 includes a support member 6 configured to rotationally support the part 4a to be detected, and equipped with a storage part 65 in which the detection part 5 is arranged at the inner peripheral side of the part 4a to be detected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
