Abstract

An assembly failure prevention device capable of effectively preventing assembly failure of assembly members onto a belt member. A tongue support device 20 of an assembly failure prevention device 10 includes a slide plate 40 having a fitting hole 42 conforming to the shape of a specific tongue plate 44. The slide plate 40 is guided by guide rail 28 and guide groove 34, and moves to a predetermined position for passing a webbing belt therethrough. If a wrong tongue plate 40 is fitted in the fitting hole 42, an insertion portion 50 of tongue plate 44 projects from the fitting hole 42. When the slide plate 40 moves in this state, the insertion portion 50 is interfered with by an end portion of the guide rail 28, and is dropped out of the slide plate 40.
