ABSTRACT:
A construction for protecting a member, such as an adjusting screw or fixing bolt, fitted to a base, from being tampered with, including a wall formed generally in the shape of a hollow tube, attached by one of its ends to the base, and surrounding the member to be protected, and a plug inserted into the other end of the wall so as to be wedged into it, with a slot being formed in the wall, extending along the axial direction of the wall from the end of the wall remote from the base, to a slot bottom at an axial position between the free end of the wall and the base, the slot bottom being closer to the base than is the part of the plug which is closest to the base, so that a gap is left between the bottom of the slot and the bottom wall of the plug for a removing tool to be inserted to lever the plug out of the end of the wall.
