Abstract: A connector unit of a drive device includes an electric power supply connector, a signal connector, a base portion and leg portions and is fixed to an opposite side of a heat sink, which is opposite from an electric motor. The leg portions are formed at an outer peripheral edge of the base portion. A cover member receives the connector unit and the heat sink in the state where the electric power supply connector and the signal connector are exposed from the cover member. A connector side O-ring is installed between the base portion and the cover member. A height position of a first end surface of each leg portion is on a first side of a second base end surface of the base portion. With this construction, it is possible to limit deterioration of waterproofness of the drive device caused by a thermal load.

Both ends of at least a number of the plurality of lateral rods being disposed inwardly of the contact surfaces.
Abstract: The front wheel suspension device for a saddle-ride type vehicle, includes a front fork having a lower end supporting a front wheel; a steering member rotatably supported by a body frame, and rotated about a rotational axis in accordance with operation of a handlebar; and a link member composed of an upper link and a lower link. The upper link of the link member has one end rockably connected to the steering member. The lower link has an upper portion rockably connected to the other end of the upper link and a lower portion rockably connected to an upper end of the front fork. A handlebar grip portion is formed at both ends of the handlebar in a vehicle width direction with the handlebar grip portion being disposed between the upper link and the lower link in a side view.
Abstract: An auxiliary motor, for a bicycle, includes an energy storage device for storing energy, a drive device for converting the energy stored in the energy storage device into kinetic energy and a transmission device for transmitting the kinetic energy onto a pedal crank spindle. The auxiliary motor is designed to be attached to a down tube of a bicycle at least parallel to the down tube and to power a pedal crank of the bicycle.
Abstract: A side covering body for a motorcycle includes an under-the-seat covering for covering a vertical gap between a seat and a vehicle body frame from an outer side and a rear covering disposed rearwardly of the under-the-seat covering. The under-the-seat covering has a front portion formed with a shroud portion that covers an outer side of a radiator and guides the incoming wind towards the radiator. The under-the-seat covering and the rear covering are connected together via a joint portion, while having respective outer side surfaces held substantially in flush with each other. The joint portion has an upper end positioned rearwardly of an intermediate portion of the seat with respect to a forward and rearward direction.

Abstract: A hovercraft includes a lift air supply source having a dynamic air flow area in communication with a central lift air chamber to provide continuous air flow to the central lift air chamber and a static air flow area in communication with an inflatable skirt extending around a periphery of the hovercraft. Air flow from the static air flow area enters the skirt to replenish air leaking from the skirt. The static air flow area has less air flow than the dynamic air flow area. The static air flow area is located at a higher position than the dynamic air flow area to reduce the likelihood of water entering the inflatable skirt when the hovercraft is operated on water.
Abstract: A vehicle driving force distribution device includes: a differential gear; a driving force transmission device; and a case member having a first accommodating chamber accommodating the differential gear and a second accommodating chamber accommodating the driving force transmission device. The case member has a first flow passage that allows lubricating oil to flow from the first accommodating chamber into the second accommodating chamber, and a second flow passage that allows lubricating oil to flow from the second accommodating chamber into the first accommodating chamber. In a two-wheel drive mode, lubricating oil flows from the second accommodating chamber into the first accommodating chamber through the second flow passage. In a four-wheel drive mode, lubricating oil flows from the first accommodating chamber into the second accommodating chamber through the first flow passage.
Abstract: A torque distribution control system comprises a torsion unit for detecting traction on wheels of a primary driving axle that is continuously engaged with a drive source or a source of torque power. The amount of traction detected is converted to a signal with variable signal strength, the signal strength correlating to the amount of traction detected by the torsion unit. The signal strength capable of being adjusted automatically based on select parameters and/or manually based on a driver's input. And, in response to the signal, actuators engage and control operations of the vehicle such as the drive source, a braking system, and/or an axle clutch, with the level of engagement dependent upon the signal strength.
