Abstract:
A duct body (101) of a blowing device provided in a chassis dynamometer comprises a bottom wall (31), a top wall (32), and a pair of lateral walls (33) that form a flow path having a rectangular cross section. In each lateral wall (33), a vertically elongated window part (42) is formed for enabling the passage of a vehicle restraint member such as a chain (5). Each window part (42) is blocked through the tiled arrangement of multiple cover plates (53, 54) and a chain plate set (100). Each chain plate set (100) is formed through the sandwiching of an elastic sheet member (61, 62) having a restraint member passage hole (63) and a slit (64) between an inner plate (51) and an outer plate (52) that each have an opening (57, 58).
