A motorcycle is equipped with a storage box disposed at a substantially upper central portion of a body frame for accommodating a helmet. The storage box comprises a storage box body having an upper opening and made of two box halves which are composed of synthetic resin. The storage box body is attached to the body frame at one end to be upwardly swingable and is secured at the other end to the body frame through an attachment bracket. A lid member is pivotally secured to the storage box body to be upwardly swingable to open or close the opening of the storage box body. The storage box body is hinged by a first hinge mechanism disposed at an outer surface of the storage box body, and the lid member is hinged by a second hinge mechanism disposed at an inner surface of the storage box to be upwardly swingable to open or close the storage box body. The lid member is locked by a lock mechanism disposed at an inner surface of the storage box body. The first and second hinge mechanisms, the lock mechanism and the attachment bracket are arranged to span the two box halves to firmly join the same with improved rigidity.
