PURPOSE: To quickly perform safe sure operation by arranging a device, by which fluid flowing down along the inside face of a loading door is drained and guided to the side corner, on the inside face of the loading door and constructing the loading door so that it is not protruded beyond the outline of a protective covering device during its motion. CONSTITUTION: A lubricant splashed to the inside face 25 of a loading door 14 during a machining process is turned into a drop because of its gravity so as to be dropped onto a trough 28 arranged on the floor side. The drops gathered in the trough 28 are discharged from a discharge port 30 on the side part. The discharging direction is set to be separated from the inside face 25 of the door 14. When an operator grips and pulls a rod 16, the lower face 24 of the door 14 moves while drawing a locus curve 44, and the door lower face 24 moves reversely toward the inside when it passes a transit area 46. As a covering part 22 is protruded toward both sides, the door 14 can be prevented from projecting beyond the outline of a protective covering device on the protective covering device side. |
