The projecting piece 82 is formed with a circular locking hole 82a. The locking hole 82a is formed to be slightly larger than the diameter of the shaft portion 80a and slightly smaller than the locking portion 80b, and penetrates the protruding piece 82.

  After the outer glass unit 83 is rotatably attached to the liquid crystal unit 81 by the outer glass support portion 51 and the outer glass support shaft portion 57, the outer glass unit 83 is rotated while being rotated toward the front surface 81g of the liquid crystal frame 81a. When the stop projection 80 is press-fitted from the locking portion 80b into the locking hole 82a, the locking portion 80b enters the locking hole 82a while being contracted inward by the wall surface of the locking hole 82a. Eventually, when the locking projection 80 penetrates the protruding piece 82, the locking portion 80b expands outward and returns to its original size, and cannot pass through the locking hole 82a, so that the liquid crystal unit 81 and the outer glass unit 83 are Integrated. As a result, the outer glass unit 83 cannot rotate with respect to the liquid crystal unit 81.

When the stop protrusion 85 is press-fitted from the locking portion 85b into the locking hole 87a, the locking portion 85b enters the locking hole 87a while being contracted inward by the wall surface of the locking hole 87a. When the locking projection 85 eventually penetrates the protruding piece 87, the locking portion 85b bulges outward and returns to its original size so that it cannot pass through the locking hole 87a, and the liquid crystal unit 81 and the inner glass unit 88 are separated. Integrated. As a result, the inner glass unit 88 cannot rotate with respect to the liquid crystal unit 81.

  Further, when an external force is applied so that the liquid crystal unit 81 and the inner glass unit 88 are separated so that the locking portion 85b is forcibly pulled out from the locking hole 87a, the locking portion 85b moves inside the locking hole 87a. Passing while shrinking inward by the wall surface of 87a, the locking portion 85b is eventually pulled out of the locking hole 87a. Thereby, the integration of the liquid crystal unit 81 and the inner glass unit 88 is released, and the inner glass unit 88 can be rotated with respect to the liquid crystal unit 81.
