A steering member for reciprocating in the right and left direction relative to a vehicle body is connected with a tie rod. The steering member is engaged with a lean control member. The lean control member is mounted on the vehicle body for swinging in the right and left direction. The lean control member is mounted with an upper end of a suspension spring. When the steering member is reciprocated in the right and left direction, the lean control member is swung according to the reciprocation of the steering member. According to the foregoing swinging, the suspension spring pushes down or pulls up vehicle wheels relative to the vehicle body. As a result, the vehicle body is inclined toward the turning center side. In this way, a driver can enjoy the same steering sense as that of a motorcycle in an automobile or a motor tricycle.
