PROBLEM TO BE SOLVED: To prevent damage of a load cell and to achieve enhancement of durability of the load cell in a garbage truck capable of measuring weight of a garbage. SOLUTION: A weight measurement device 6 is provided with the compression type load cell 11 fixed to an upper surface of a cross member 2a of a chassis 2; a spherical bearing 12 fixed onto the load cell 11; and a support member 13 provided so as to penetrate through the spherical bearing 12 and a baggage box frame 5 respectively. The spherical bearing 12 is provided with an inner ring member 16 having a cylindrical hole; and an outer ring member 17 having a spherical cavity portion inside. The inner ring member 16 is fitted into the cavity portion inside of the outer ring member 17. The inner ring member 16 is retained by the outer ring member 17 so as to become relatively pivotable along an inner wall surface (recessed spherical surface) of the outer ring member 17. The other end of the support member 13 is inserted to a hole of the inner ring member 16. According to such a constitution, the support member 13 is pivotably supported on the spherical bearing 12.
