Abstract: A column and beam connection structure for connecting a steel H-beam to a column uses an external diaphragm. The external diaphragm includes a plurality of divided diaphragm segments such that each diaphragm segment has a column plate abutting on the column. A diaphragm segment which is arranged along the steel H-beam among the plurality of divided diaphragm segments has a beam plate installed in a flange of the steel H-beam. The beam plate has an end portion in which the column plate is provided. A joining surface between the diaphragm segments is placed in a vicinity of a corner portion of the column so that only the column plate of one of the diaphragm segments abuts on each column surface of the column. A joining member fastens to fix between the diaphragm segments such that contact pressure is applied from the column plates to the surface of the column.

Abstract: In a vehicle with a load-carrying platform, an elastic band is provided so a rear portion of a tailgate and a rear portion of a bed extender enter a tensioned state. A rotation regulation mechanism is provided to the tailgate and the bed extender that regulates further rotational movement by the tailgate and the bed extender making contact when the tailgate is rotated towards a closed position. The bed extender and the tailgate are prevented from rotating in the same direction by the rotation regulation mechanism, and the load on the elastic band is mitigated.

Abstract: A straddled vehicle is equipped with a charging port structure in which a charging port is fixedly disposed within a recess provided in a wall member. A base end part of a cover member capable of closing the charging port is pivotably supported at a position adjacent to the charging port, and a lid is capable of closing the recess so as to cover the cover member from the outside is pivotably supported on the wall member. A retaining member retains a closed state of the lid in response to the lid being closed. A releasing member is operable so as to release the retention of the closed state of the lid by the retaining member. A coupling member is operable in association with the operation of the retaining member when closing the lid, and pivots the cover member toward the closing side.

Abstract: A vehicle approach notification apparatus for an electric motorcycle, which outputs notification sound for notifying a walker or the like of approach of a vehicle from a speaker attached to a vehicle body includes a control unit for controlling the notification sound. The control unit is attached to a position, displaced rather forwardly of the vehicle body, of a bottom face in an accommodating box disposed below a seat of the electric motorcycle. A cover plate, which configures part of the bottom of the accommodating box, is removably disposed above the control unit. A low voltage battery as a power supply for auxiliaries is accommodated on the bottom of the accommodating box displaced rather rearwardly of the vehicle body from the control unit. The cover plate is disposed so as to cover an upper portion of the low voltage battery in flush with an upper face of the control unit.

Abstract: A storage structure of a saddle riding type vehicle with enhanced ease of storage and removal of small storage articles. An article storage unit is provided so as to include an opening in a rear surface of a front portion cover and at a position facing a rider and to be longer in a longitudinal length extending in a vehicle longitudinal direction relative to a height direction. In addition, a removable tray including riser walls along its periphery is disposed at a position closer to a lid than an inner wall of the article storage unit.

Abstract: An electric motorcycle includes a front cover for covering a head pipe of a vehicle body frame from a forward direction and a speaker for notifying an individual, such as a walker or the like, of the approach of a vehicle. The speaker has a sound emitting direction directed forwardly on the vehicle body and is disposed at a position on the opposite side to a key cylinder of a main switch, which is disposed in a vehicle body sideward direction of the head pipe, across the head pipe. A front stay support a front carrier disposed on the vehicle body front side of the front cover and is attached to the vehicle body front side of the head pipe is provided on the vehicle body rear side of the front cover. The speaker is disposed above the front stay as viewed in front elevation of the vehicle body.

Abstract: A frame structure for a saddle-ride type vehicle includes a body frame having a head pipe, down tubes, seat rails and upper tubes and a unit swing power unit swingably supported by the body frame. The seat rails have front ends joined to downwardly extending portions of the down tubes. The down tube has a second bending portion formed at the rear end of the horizontal extending portion and an obliquely upwardly extending portion extending rearwardly and upwardly at a position behind the second bending portion. The obliquely upwardly extending portion has a rear end joined to the seat rail. The power unit support portion is formed behind the bending portion.
