(54) Front loader


(57) This disclosure provides a front loader which improves operability in a low position operating state. The front loader includes a mechanical posture maintaining mechanism (16) for maintaining the posture of an implement, regardless of swing displacement of a boom (12). The boom (12) is formed in a curved shape in which a longitudinal central side thereof is located above. The posture maintaining mechanism (16) includes a swing link member (28) having an inner free-end part (28A) and an outer free-end part (28B) and disposed at a longitudinal center location of the boom (12) so as to be swingable about a third horizontal pivot (29) as a fulcrum, a base-end link member (30) extending between a fixed bracket (10) and the inner free-end part (28A), and a free-end link member (31) that links the outer free-end part (28B) to the implement. The boom (12) is provided with a base-end boom part (12K) located on the first pivot side from a peak (12a) that is furthest from a center-to-center straight line (La) and a free-end boom part (12L) located on the second pivot side from the peak (12a), and the free-end boom part (12L) is provided with a third pivot (29).
