[Effect of the device]

 According to the present invention, the following effects can be achieved. (a) The rotation lever can be easily pivotally attached to the board by simply inserting the engaging pin into the shaft hole of the boss at the same time as fitting the outer cylinder into the boss. The assembly work can be performed more quickly than the conventional one.

(B) It is convenient for storage and handling before assembly because it does not require minute parts such as the conventional engaging pin, and the number of parts is only two parts, the board and the rotation lever. Also, each component can be easily manufactured by integral molding of synthetic resin material or the like.

(C) In the conventional one in which the rotary lever is sandwiched between the head portion of the engaging pin and the large-diameter portion of the boss portion, a gap is formed on both sides of the rotary lever, whereby the rotary lever is rotated. The lever may tilt or rattle, but according to the present invention, the fitting of the outer cylinder part, the boss part and the engagement pin guides the rotation of the rotation lever. The possibility of tilting the rotating lever is small, and since the gap is formed only on one side surface of the rotating lever, the rotating lever is less likely to rattle.
