To provide a front-wheel suspension device for a saddle-riding type vehicle, which is able to reduce weight and cost.SOLUTION: A front-wheel suspension device for a saddle-riding type vehicle comprises an under-bracket B fixed to the periphery of a steering shaft S by means of welding, and coupling a front-wheel support member to the steering shaft S. The under-bracket B has a top plate 4 having an insertion hole 40 in which a steering shaft S is inserted and also having, at an edge part of the insertion hole 40, a bend part 4a bending upward. On the upper end of the bend part 4a is a placing surface 4b on which an inner ring 31 of a lower rolling bearing 3 interposed between a head pipe P and the steering shaft S is placed.SELECTED DRAWING: Figure 3
