In addition, the stationary moving body 41 is formed to enclose the lower fixed bar 322 and the lower movable bar 342 having a rectangular cross-sectional shape, and is movable along the lower fixed bar 322 and the lower movable bar 342 .

The mounting extension 42 is coupled to each mounting body 41 and extends upward, and the mounting insert 43 is connected to the mounting extension 42. The mounting insert 43 can be inserted into the part 100 with its section reduced toward the upper end. For example, both side surfaces of the mounting insert 43 may have a slope or a curved line. This allows the mounting insert 43 to be inserted into the mounting hole 101 of the component 100 having various diameters to support the component 100. [ A portion of the component 100 is moved in the left and right directions in the storage portion 10 so as to be in point contact with the mounting insert 43 to thereby support the contact point between the mounting hole 101 and the mounting insert 43 Painting is possible.
