The present invention relates to a guide bush, which is provided with a plurality of bush elements assembled such that, as a whole, said bush elements form a cylindrical shape. The plurality of bush elements is provided with a fitting cylinder part. The fitting-cylinder part is fitted inside a fitting-holding section of a housing, and is provided with an inner peripheral surface configured so as to guide, in a manner enabling displacement in an axial direction, an outer peripheral surface of a displacement shaft inserted inside the fitting-cylinder part. The diameter of a circumscribed circle of the plurality of bush elements in a state in which end surfaces thereof in a peripheral direction are brought into contact with each other is not more than the internal diameter of the fitting-holding section.
