To solve the problem that in a washing device for intermediate and finishing processing for a work part, it is necessary to substantially completely remove water after washing, and in this case, normally the work part is once separated from a transport conveyer manually or using a robot or the like, and although reversion or the like is used in separating time, the method is inefficient, many hands are required, and the work is stopped in the midway in an assembly line intending continuous processing.

In this reverse type transport conveyer, a pair of transport conveyers is a drive side transport conveyer provided on a frame and a driven side transport conveyer provided on the frame to reverse/return. The drive side transport conveyer is provided with a driving part, a transmission means is provided between the drive side and driven side transport conveyers, and the driven side transport conveyer is provided with a reverse/return operating part.
