Claims (1)

[Scope of utility model registration request] A link device that is incorporated into a locking device for a sliding door shoji that locks the sliding door shoji by rotating one of a pair of handles provided inside and outside the sliding door shoji, and that causes the pair of handles to interlock with each other. A pair of pieces having a non-circular hole at the center of rotation into which the shafts of the pair of handles are inserted are rotatably mounted on both sides of the base, and one end of each piece is pivotally attached to a portion of each piece that is away from the center of rotation. In a link device for a sliding door shoji lock device in which the other ends of a pair of connecting arms are pivotally connected to each other, a pivoting portion between a piece provided with one handle and one end of one connecting arm, and a connection of this one. By providing a sliding part between the shaft and the elongated hole in at least one of the pivot parts between the other end of the arm and the other end of the other connecting arm, one handle can be attached to the other handle. The handle can be rotated independently by a certain angle, and between this one handle and the base for attaching this handle to the vertical stile of the sliding door shoji, there is a handle that allows the handle to be moved toward the rotatable end. A link device for a locking device for sliding door shoji, which is equipped with a spring.
