Indicate device using handle device for open and shut

The present invention relates to an indicator device for a door lock handle which includes an indicator displaying a locking state in which a handle is locked by a lock unit, and a change to an unlocking state in which the handle is unlocked, and is manufactured in a simple structure, thereby easily recognizing the locking state of a door, and improving productivity. In the prior art, a structure of an indicator device was complex, operating was inconvenient, and a connection state of a display window was complex, thereby causing inconvenience in use. The present invention includes a control plate (40) installed on a rear surface of a lock unit (30) to be rotatable; a guide protrusion unit (46) formed on one side of the control plate (40), and having an arc-shaped recessed coupling groove (44) formed inside; a locking protrusion (52) fitted and bound to an inner portion of the recessed coupling groove (44) of the guide protrusion unit (46), and protruded from a lower portion of an indicator (50); and a see-through window (60) supporting and accommodating both surfaces of the indicator (50).
