    • PROBLEM TO BE SOLVED: To provide a rotation detector for suppressing the variations of the pulse width of a pulse signal following the on/off operation of a lead switch.
      SOLUTION: The rotation detector comprises a frame 1; a rotary magnet 3 that is accommodated in the frame 1 and responds to a rotary shaft 2; a pair of contacts 15A that operate according to a change in magnetism; a sealing pipe 15B for sealing the periphery of the contact section 15A; and a pair of lead sections 15C extended from the contact section 15A to the outside of the sealing pipe 15B. The rotation detector also has a lead switch 15, where the contact section 15A is operated, according to the rotation of the rotary magnet 3. Further, the lead switch 15 is fitted to the frame 1 through a holder 16 for retaining the lead switch 15, and a magnet M for adjusting magnetic flux operating on the contact section 15A or the lead section 15C is press-fitted and fixed at the holder 16 in the rotation detector.
