In addition, the outer surface of the main body 41 is formed into a hemispherical shape in this example, and a flange portion 44 that is approximately perpendicular to the axis of the through hole 42 is formed on the peripheral edge of the outer surface, and a flange portion 44 that is slightly spaced apart from the flange portion 44 is formed on the periphery of the outer surface. Several protrusions 45, 45 are formed, and a locking portion 46 is further formed. The locking portion 46 protrudes laterally from the outer surface of the main body 41 (in the direction in which the flange portion 44 protrudes), and is bent and protrudes toward the flange portion 44 to have a substantially L-shaped cross section. It is configured so that it reaches into the notch 44a formed in the hole and has restoring elasticity. In addition, the flange portion 44
A plurality of grooves 44b extending to the main body 41 are formed radially. In addition, 47 is a protrusion, which is attached to the main body 4.
The projections 47 are formed to protrude radially from the outer surface of the screw holder 4, and the projections 47 are for engaging with a tool or the like for rotating the screw holder 4 when the screw holder 4 is installed.

The adjusting screw 5 has a thread formed on its shaft portion 51, and a spherical head 52 that matches the spherical receiving portion 43 of the screw holder 4 described above is formed on one end side. An operating section 53 having a groove 53b that can be operated with a tool such as a screwdriver is formed protruding from the tip of the shaft section 52 (on the side opposite to the shaft section 51). The operating portion 53 in this example has a cylindrical shape and has a length that projects from the through hole 42, and the groove 53b has a cross shape. The shaft portion 51 of the adjusting screw 5 is screwed into a screw mounting 21 made of synthetic resin fixed to the mounting base 2, and the spherical head 52 has a spherical receiving portion 4 of the screw holder 4.
