Abstract
An inclination sensor having excellent rotational performance, longlasting stability and high sensing precision. The inclination sensor comprises a pendulum (10) rotatably attached to a case (1) of a fixed body secured to an attached member, a magnetic flux-generating means (11) attached to the pendulum (10), reed switches (4a) and (4b) attached to part of the case (1) corresponding to the locus along which the magnetic flux-generating means (11) moves, and a flange portion (12) which is a damping body being nonmagnetic and electrically conductive and disposed in the case (1) along the locus of the movement of the magnetic flux-generating means (11).
