PROBLEM TO BE SOLVED: To provide a plate slide device which increases the effective area of a base plate, reduces relative movement between the base plate and the plate slide device, and consequently can reduce its performance loss.SOLUTION: A plate slide device (18) for a base plate (16) of a compaction device (10) for processing a ground surface part (20) has: a first surface (34) mounted on the ground surface part (20) for processing; and a second surface (36) contacting with a bottom surface (28) of the base plate (16) when the plate slide device (18) is fixed to the base plate (16). The bottom surface (28) and the second surface (36) have progressions corresponding to each other. A molding component (18) can be fixed to the base plate (16) substantially without cavities. |
