WORK TREATMENT APPARATUS AND WORK WASHING METHOD

PROBLEM TO BE SOLVED: To provide a work washing device for certainly washing a work without damaging the same. SOLUTION: The work W is charged in the rotary drum 3 of the work washing device 1 (W1) and delivered to a work feed fine 22 on the downstream side from a work feed fin 21 on the upstream side by rotating the rotary drum 3 in a first rotary direction CCW so as to exceed a stepped part 50 for a work guide (W2). When the rotary drum 3 is reversely rotated, the work W is guided to a work capturing pocket 40 by the stepped part 50 for the work guide to be captured in the pocket 40 (W4). A washing liquid is sprayed on the work W while forward and rearward rotating the rotary drum 3 in a state the work W is captured in the work capturing pocket 40 to wash the work W. After washing, the work W is discharged from the work capturing pocket 40 by rotating the rotary drum 3 in a first rotary direction once or more and fed by the work feed fin 22 to be delivered to the work feed fin 23 on the downstream side.
