PROBLEM TO BE SOLVED: To provide a suspension device for a carrying vehicle that can feed sufficient grease to specific narrow regions such as an upper sliding portion of one end portion positioned near the center in a vehicle width direction of a supporting portion where contact pressure is maximized and a lower sliding portion of the other end portion positioned at the side in the vehicle width direction of the supporting portion, of sliding portions formed between a cylindrical supporting portion of a trailing arm and a torque tube inserted through the supporting portion, in a simple structure.SOLUTION: The suspension device for a carrying vehicle, which has a first grease feeding port 30 provided at a peripheral wall portion that is a peripheral wall forming one end portion positioned near the center in a vehicle width direction and is positioned in the upward when viewed from a side in the vehicle width direction of one supporting portion 16 of a trailing arm; and has a second grease feeding port 31 provided at a peripheral wall portion that is a peripheral wall forming the other end portion positioned at the side in the vehicle width direction and is positioned in the downward when viewed from the side in the vehicle width direction of the opposite supporting portion 16 of the arm, supplies intensively lubricant only to specific narrow regions α, &bgr; where contact pressure is maximized. |
