As shown in FIGS. 8 and 9, a fixed shaft 11 to be described later protrudes from the center of one surface (between the screw insertion holes 10 on the left and right sides).
As shown in FIGS. 2 to 7, the stopper lever 3 has one end formed in a substantially cylindrical shape by a metal material such as zinc die casting or a synthetic resin material, and has a circular front portion 31 and a cylindrical peripheral surface portion 32. The other end side is formed in a long and narrow box shape vertically from one end of the cylindrical shape, and becomes the left and right side portions 34 and the other end continuous to the elongated rectangular front portion 33 and the peripheral surface portion 32 at one end. Each side surface portion 34 on the other end side is formed in a substantially L-shape in a side view when extending from the bottom surface portion 35 together with the bottom surface portion 35, and has a predetermined range from the other end toward one end. This is a convex shape 36. The stopper lever 3 is hollow and has a reinforcing portion, and the back side is opened.

As shown in FIGS. 2 to 7, the stopper lever 3 is attached to the attachment base 1 via a shaft 2 so as to be able to rotate 360 ° about the shaft 2 as a rotation center. In this case, as shown in FIGS. 8 and 9, the shaft 2 includes a fixed shaft 11 on the mounting base side which is formed so as to protrude substantially in the shape of a shaft on the mounting base 1, and a stopper lever formed inside the stopper lever 3. And a double-sided shaft 37 on the side. The fixed shaft 11 on the mounting base side has a substantially axial shape at the center of the mounting base 1 (between the screw insertion holes 10 on both the left and right sides). In this case, the mounting shaft 11 has a tapered shape that gradually increases in diameter from the distal end toward the proximal end. The inside of the mounting base 1 is opened and penetrated, and the inside is a through hole 12 whose diameter is slightly enlarged at the end on the mounting base 1 side. The double-sided shaft 37 on the stopper lever side is a part of the stopper lever 3, in this case, one end is formed in a substantially cylindrical shape having a double, and has a screw hole 380 inside, and the fixed shaft 11 of the mounting base 1. The inner shaft 38 that can be inserted into the through hole 12 and the outer shaft 39 that can be fitted onto the outer peripheral surface of the fixed shaft 11 of the mounting base 1.
The mounting base 1 and the stopper lever 3 are configured such that the inner shaft 38 of the stopper lever 3 is inserted into the through hole 12 of the fixed shaft 11 of the mounting base 1 and the outer shaft 39 is on the outer peripheral surface of the fixed shaft 11.
