As a binding device of this type, an elongated piece-shaped base having one of two binding rods is connected to one end of the base in the longitudinal direction so as to be rotatable in a plane, and at the tip of the binding rod. 2. Description of the Related Art There is known a rotating member provided with another binding rod which is in contact with and forms a closed loop. In this type of binding device, the engaging members provided on the free end side of the rotating member are engaged with the ends of the base, so that the tips of the opposing binding rods abut against each other to be in a binding state. On the other hand, by releasing the engagement by the engagement member, the binding rods can be separated from each other.

となる。In the above configuration, the binding rod 20 is in the binding state at the position where the engaging projection 35 of the binding rod 20 contacts the side end surface 32 of the slider 18. Here, when releasing the binding rod 20, the operating portion 31 of the slider 18 may be pinched and pulled out from the base 17. By this drawing, when the engaging projection 35 reaches the inside of the notch recess 33, the engaging projection 35 is disengaged, and thereby the binding rod 20 can be rotated in the opening direction. When the binding rod 20 is opened, the slider 18 is pulled into the base 17 by the above-described tension spring. In this state, when the binding rod 20 is rotated to return to the binding state, the engagement convex portion 35 becomes the notch inclined surface 33 </ b> A of the notch concave portion 33.
The operation unit 3
1 moves the slider 18 in a direction slightly protruding from the end of the base 17. When the inner surface of the engaging projection 35 is located on the outer surface of the side end surface 32 of the slider 18, the slider 18 is retracted again. Side end face 32 and engaging projection 35
Are engaged with each other, and the binding state is maintained again.
