Abstract
A linear motion mechanism is provided with a shaft extending along an axis, a drive mechanism which moves the shaft in the axis direction, a housing which accommodates the drive mechanism and which has an opening allowing one end portion of the shaft to project to the outside so as to be capable of moving backward and forward, and a tubular protective cover of which the two ends are fixed to the housing and the end portion of the shaft. The protective cover encloses the opening and the part of the shaft that projects outward from the opening, expands and contracts in the axis direction with movement of the shaft relative to the housing in the axis direction, and is fixed to the housing in a position in which a part of the drive mechanism including an end surface through which the shaft projects is disposed inside the protective cover.
