Abstract

PROBLEM TO BE SOLVED: To prevent a mounted interlocking rod from moving at random in the lateral direction by clamping the interlocking rod with pair of upper and lower clamping pieces protruded from the back side face of a front face plate and makign the back face of the interlocking rod opposed to the front face of a hook shaped stopper protruded backward from the back face of the front face plate. SOLUTION: An interlocking rod 18 is enabled to be attached/detached on the back face side of a front face plate 9. The interlocking rod is prevented from moving in the longitudinal and lateral directions by upper and lower clamping pieces 17 and a stopper 16 and the outer end parts of the interlocking rod 18 are supported by the end of a supporting member 31. The interlocking rod 18 can be smoothly rotated. Since movement of the interlocking rod 18 in the lateral direction is blocked by a stopper piece 22, a protruding piece 19 is positioned usually just before a sideward protruding piece 15 and a pressing piece 21 just after a pressure receiving part 28, so those do not mutually miss-swing. The front face plate of the drawer can be easily replaced with another front face plate with different color and quality to reduce the number of parts and assembling the front face plate device 8.
