PROBLEM TO BE SOLVED: To provide bad road durability test equipment, capable of performing durability test in which a bad road is simulated, without contaminating an external environment, with a simple structure.SOLUTION: Bad road durability test equipment 1 comprises: an air permeable bag part 10 attached to cover surrounding of slide parts on plural slide members (cylinder Sand piston rod S) for repeating relative displacement, and tracking to repetitive motion of the slide members for deforming; powder 20 included in the bag part 10; and a blow part 30 for blowing air into the bag part 10. The air is blown into the bag part 10, thereby the powder 20 can be preferably dispersed in the bag part 10. Because the bag part 10 can deform by the slide members, adhesion of the powder 20 to an inner wall of the bag part 10 can be prevented, and the powder can be preferably dispersed.SELECTED DRAWING: Figure 1 |
