Abstract: A brake control device for a brake system. The control device can perform both an interlocking brake control and an antilock brake control. The brake system includes a front-wheel hydraulic circuit, a front-wheel-side braking part; a rear-wheel hydraulic circuit, a rear-wheel-side braking part; and an electrically-operated pump which pressurizes the brake fluid. The brake control device includes a usual voltage mode where the interlocking brake control or the anti-lock brake control is performed when the supply voltage is a first voltage or more, and a low voltage mode where at least one of the interlocking brake control and the anti-lock brake control is performed in a limited manner when the supplied voltage is a second, lower voltage. An operation mode is changed from the usual voltage mode to the low voltage mode when it is determined that the supply voltage becomes lower than the first voltage.

Abstract: A motorcycle comprises an electricity accumulator configured to supply electric power to driving devices required for driving of the motorcycle and to non-driving devices; a voltage detector configured to detect a voltage of the electricity accumulator; and a power supply controller configured to control supply of the electric power; the non-driving devices including electric motor devices in an electric motor braking system configured to be electrically driven to assist braking and non-driving electric motor devices other than the electric motor devices in the electric motor braking system; and the power supply controller being configured to inhibit the electric power from being supplied to at least one specified non-driving electric motor device of the non-driving electric motor devices, when the voltage of the electricity accumulator which is detected by the voltage detector is not more than a first predetermined voltage.

Abstract: An output control unit of a vehicle, having a front riding space and a rear riding space, includes a riding detection device for detecting the presence of a passenger in the rear riding space. When the riding detection device detects the passenger, the output control unit regulates the output of the engine as compared with the output when the riding detection device does not detect a passenger in the rear riding space.

Abstract: A vehicle includes a front seat and a rear seat that is changeable between an installed state in which the passenger can be seated and a retracted state in which the passenger is not seated and the rear seat is retracted. The vehicle includes an output control unit controlling the output of an engine, and a detection device for detecting the installed state of the rear seat. When the detection device detects the installed state of the rear seat, the output control unit regulates the output of the engine as compared with the output when the detection device does not detect the installed state of the rear seat.

Abstract: A pick-up style utility vehicle including a front seat, a rear seat and a cargo bed in order from the front side to the rear side of the vehicle, and a screen for partitioning the cargo bed and ride space on the front side of the cargo bed. The cargo bed has at least a stationary bottom plate and an expansion bottom plate, and is changeable between an expanded state where the cargo bed is expanded forward into the ride space and a non-expanded state where the cargo bed does not occupy the ride space. Also, the expansion bottom plate is pivotable on a horizontal shaft in the right and left direction relative to the stationary bottom plate and the screen.

Abstract: A vehicle according to the present invention includes a front seat and a rear seat. The rear seat is changeable between an installed state in which the passenger can be seated and a retracted state in which the passenger is not seated and the rear seat is retracted. The vehicle includes an output control unit controlling the output of an engine, and detection means for detecting the installed state of the rear seat. When the detection means detects the installed state of the rear seat, the output control unit regulates the output of the engine as compared with the output when the detection means does not detect the installed state of the rear seat.

Abstract: According to the present invention, an output control unit of a vehicle having a front riding space and a rear riding space, includes: riding detection means for detecting the riding of the passenger in the rear riding space; wherein when the riding detection means detects the riding of the passenger, the output control unit regulates the output of the engine of the vehicle as compared with the output when the riding detection means does not detect the riding of the passenger.

Abstract: A venting aperture is formed in an upper wall of a casing, a gas-permeable membrane supporting body is mounted to the casing so as to communicate between the venting aperture and an external portion through a communicating aperture, and a gas-permeable membrane is disposed so as to shut off the communicating aperture. A cylindrical protective wall is disposed so as to protrude integrally from the casing so as to surround the gas-permeable membrane supporting body. A leading edge region of an external surface of the protective wall is formed so as to have an inclined surface in which a wall thickness gradually decreases from a root end toward a leading edge, and a groove having a groove direction in a direction of projection of the protective wall is formed so as to extend from a root of the protective wall to a leading edge and so as to communicate between an internal portion and an external portion of the protective wall.
