The bracket holding member 26 does not move downward because the support shaft 38 is engaged with the horizontally long hole 28 of the receiving portion 27, so that the support shaft 38 moves above the arc-shaped hole 32 and is used for angle adjustment. The engagement protrusion 39 engages with the upper concave portion 34, and the upper end of the bracket holding member 26 is inclined in a direction away from the moving member 25 (see FIGS. 9 and 13B). The horizontally long hole 28 of the receiving portion 27 allows a lateral displacement of the support shaft 38 that occurs when the angle adjusting engagement projection 39 is disengaged from the concave portion 34.

When the manual operation arm 35 is pulled upward, the sliding protrusion 33 moves up along the guide slot 30 together with the moving block 25 (see FIG. 10), and the positioning protrusion 3 is moved.
6 engages with the upper engaging groove 31 (FIGS. 11 and 13).
(C)). The moving block 25 has two sliding protrusions 3.
Since 3 is engaged in the guide slot 30, it does not tilt even if it rises.

Since the bracket holding member 26 does not move upward, the support shaft 38 moves below the arc-shaped hole 32, the angle adjusting engaging projection 39 engages with the upper concave portion 34, and the bracket holding member 26 The upper end is inclined in a direction approaching the moving member 25 (see FIGS. 12 and 13C). Therefore,
The mounting angle of the bracket holding member 26 can be adjusted without changing the position of the bracket holding member 26 in the vertical direction.

[0026]

As described above, the present invention has the following advantages. (1) The angle of the bracket holding member can be finely adjusted by a simple operation of moving the moving block up and down, and the angle-adjusted bracket holding member is adjusted by engaging the positioning projections with the engagement grooves. Since the angle is maintained, fine adjustment of the protector mounting angle is easy. (2) Even if the angle of the bracket holding member is adjusted, the position of the bracket holding member with respect to the protector does not fluctuate, so no troublesome work of adjusting the position of the bracket holding member when adjusting the angle of the bracket holding member is required. This makes it easy to adjust the mounting angle of the protector.
