In a motor power transmission device (), wherein rotational power of an electric motor () is input to a sun gear () of a planetary speed reducer (), and then the rotation of the sun gear () is converted to rotation of a planetary carrier (), and wherein the planetary carrier () rotatably supports planetary gears () and converts revolving motion of the planetary gears () into rotating motion, and the rotation of the planetary carrier () is then output to an output shaft (), a torque limiter mechanism () is interposed between the planetary carrier () and the output shaft (). Thus, even if excessive back torque is input to the output shaft, transmission of the back torque to the speed reducer is blocked to protect the speed reducer.

Motor power transmission device

An air bag jacket includes a first portion corresponding to a breast and an upper back portion of a user in a wearing state and a second portion corresponding to a belly and a waist of the user in a wearing state. A recessed portion is cut upwardly from a skirt is formed in the second portion at a position corresponding to either a right or left side of the user. An inflator is arranged on the inside of the recessed portion.

An electric motorcycle in which a power drive unit and a motive power generation motor for traveling are secured to a swing arm swinging around a pivot shaft, and power from a battery is supplied through the power drive unit to the motive power generation motor. A hollow inside of the swing arm is partitioned into an air introducing space and an equipment fixing space by a partition wall. The power drive unit is secured in the equipment fixing space so as to be in close contact with the partition wall and a fin extending from the partition wall to the air introducing space are formed at a fixing surface of the air introducing space to which the power drive unit is attached.

A fuel cell two-wheel vehicle is provided with: a fuel cell, fuel tanks, a supercharger, a pipe line, an in-wheel motor, and a motor driver. The fuel cell generates electric power using hydrogen and air as reaction sources. The fuel tanks supply hydrogen to the fuel cell through a hydrogen supply path. The supercharger supplies air from the outside air to the fuel cell. Through the pipe line, an exhaust from the fuel cell is discharged to the outside. The in-wheel motor serves as a driving source of the fuel cell two-wheel vehicle, and the motor driver drives the in-wheel motor. In an air system, a route and an outlet of the pipe line are arranged to be directed toward the motor driver. Thus, a heat sink is exposed to the discharged air having passed through the fuel cell, and thereby the motor driver is cooled.

Cooling apparatus of fuel cell vehicle

An electric motorcycle is provided such that even if a power drive unit is mounted to a swing arm, it is difficult for a load to be applied to wiring connected to the power drive unit. In an electric motorcycle in which a PDU and a running-purpose power-generating motor are attached to a swing arm turning around a pivot shaft, and electricity from batteries is supplied via a contactor box to the PDU, from which the electricity is supplied to a power-generating motor, torsional portions extending generally parallel to the pivot shaft are provided at a portion of output lines connecting the contactor box with the PDU so as to allow torsion to absorb swinging movement of the swing arm.

A layout for an exhaust pipe which also serves as a drainage pipe which prevents splashing of water generated in a fuel cell toward a passenger or splashing toward a tire. Humid excessive gas supplied from a fuel cell is diluted in a dilution box by off-gas discharged from the fuel cell and is used for humidifying air in the humidifier. An exhaust pipe is connected to the dilution box, and diluted hydrogen gas is discharged via the exhaust pipe. Vapor mixed in hydrogen gas is condensed in the exhaust pipe and turned into water, which is drained through the exhaust pipe that extends rearwardly of a vehicle body through the interior of a power unit. A discharge port of the exhaust pipe (which is also a drainage port for water generated in the fuel cell) is positioned at the widthwise center of the vehicle body.

Drainage structure in fuel cell motorcycle

An electric motorcycle in which the disposition space of a motor is downsized, the number of components is reduced, and the power transmission efficiency is improved. In an electric motorcycle, a swing arm is swingably supported by a vehicle body frame and supports a power generating motor. A driving shaft of the power generating motor and a rear wheel axle of a rear wheel are coupled together. A driving force of the power generating motor is transmitted to the rear wheel. In the electric motorcycle, the driving shaft of the power generating motor is disposed generally in parallel to the rear wheel axle of the rear wheel. A driving gear is provided on the driving shaft. A driving gear is in meshing engagement with a reduction gear provided on the rear wheel axle. The driving gear has a smaller diameter than that of the reduction gear. A driving force of the power generating motor is transmitted to the rear wheel axle through a reduction.

An airbag jacket, to be fitted in a rider jacket, includes an airbag body configured to fill with gas from an inflator operatively connected with the airbag body. The airbag body includes a flat front piece, a flat back piece substantially identical to the flat front piece; the flat front and back pieces having an opening formed therein for permitting an user of the airbag jacket to pass his or her head therethrough. The flat front and back pieces are joined together along a peripheral boundary thereof and along a peripheral boundary of the opening by sewing or bonding so as provide a plurality of continuously formed body covering portions including at least a back covering portion, a shoulder covering portion and a front covering portion.
