る回転角センサ。An optical fiber wound in a loop around an elastic body is held between a pair of movable pieces that engage with a linear groove provided in a substrate of a main body so as to be movable in a direction toward and away from each other. One end of a rotary ring provided on each of the movable pieces of is engaged with a pair of guide grooves formed in a rotary cam that is connected to an external rotary body and rotates, and according to the rotation angle of the rotary body. A rotation angle sensor that clamps the loop-shaped optical fiber with a movable piece and detects the rotation angle of a rotating body from a change in the transmittance of light propagating within the optical fiber, the sensor having a guide groove having the same shape as the rotating cam. Another rotary cam is provided as a pair at a position facing the rotary cam with the loop-shaped optical fiber sandwiched therebetween, and the other end of the rotary ring of the movable piece is engaged with the guide groove of the other rotary cam. A rotation angle sensor characterized by:
