  • Patent number: 10267077
    Abstract: This rotation mechanism is provided with: a first member; a second member which is rotatably coupled to the first member by a pivot; and a torsion coil spring which applies force such that one from among the first member and the second member is rotated relative to the other. Any one of the first member and the second member is provided with a torsion coil spring-accommodating part in which a pair of protrusions facing each other in the axial direction of the pivot is provided. The pair of protrusions are configured so as to hold, around the axes of the protrusions, the two end portions of the coil shape of the torsion coil spring, and so as to protrude while being displaced in the radial direction of the coil shapes forming the two ends, with respect to the axial direction of the pivot.
