To largely secure position adjustment amount in a longitudinal direction of a steering shaft without changing a head pipe in a front wheel steering device of a motorcycle.
In a front wheel steering device of a motorcycle, a head pipe 8 at a front end of a vehicle body frame includes a pair of upper and lower bearing support sections 8a and 8b, and an upper side shaft end 10a and a lower side shaft end 10b of a steering shaft 10 are respectively rotatably supported on both of the bearing support sections 8a and 8b via bearings 20 and 30. In the front wheel steering device, a shaft intermediate section 10c between the upper side shaft end 10a and the lower side shaft end 10b is formed so that a gravity center line O2 of the shaft intermediate section 10c is deflected in a longitudinal direction with respect to a rotation center line O1 of the steering shaft 10.
