    • A vibration-isolating device for a steering wheel of a travelling working vehicle equipped with a wheel steering mechanism includes a first steering shaft (32) that transmits rotational displacement, the first steering shaft being operatively connected to the steering wheel (7); a second steering shaft (33) that transmits rotational displacement, the second steering shaft being operatively connected to the wheel steering mechanism (P, 23); and a vibration-isolating connecting mechanism (31) that operatively connects the first steering shaft (32) and the second steering shaft (33) to each other so that rotational displacement can be transmitted. When the angles of rotational displacement of the first steering shaft (32) and the second steering shaft (33) are within ranges of rotation angles for linearly driving the vehicle, rotational displacement cannot be transmitted between the first steering shaft (32) and the second steering shaft (33).

    • A boom assembly is bent at a longitudinal center portion thereof to present an upwardly convex shape. The assembly includes a front boom body and a rear boom body. The front boom body and the rear main body each includes a main body consisting essentially of a pair of right and left lateral plates and a top plate interconnecting upper edges of the respective lateral plates. The main body is formed with an upper face and a lower edge thereof being bent in a longitudinal direction thereof into an arc face having a predetermined radius of curvature. The front or rear main body further includes a bottom plate disposed downwardly of the top plate and between the right and left lateral plates. Each main body is formed by bending a plate member into a reverse U-shaped cross section and each bottom plate is comprised of a plate member provided separately from the plate member forming the main body.
