Abstract: A register includes an operation knob which is slidably assembled to a selected one of front horizontal blades and which is connected to a selected one of rear vertical blades via a connection mechanism. The connection mechanism includes a connection pillar portion formed integrally with an intermediate portion of the selected vertical blade, the connection pillar portion having a generally circular cross section and being located at a position deviating from a rotation axis of the selected rear vertical blade, and a pair of connection arm portions extending rearward from the rear end of the operation knob with a predetermined space formed therebetween. The operation knob is connected to the selected vertical blade in a state where the connection pillar portion is rotatably inserted into an engagement groove between the connection arm portions.
