Abstract: A bicycle simulation system that can be easily transported includes a frame, a steering handle operated by a rider, a left-right pair of pedals to be operated by the rider for rotating a flywheel, two front forks for supporting the head tube and a rotatable rear wheel. The rear wheel is grounded on a floor so that it supports the frame, together with the front forks. The bicycle simulation system ensures that the operations of a brake lever are accompanied with the same feeling as that in operating a real bicycle. A brake lever is operated by the rider with a drum brake for frictionally braking the rotation of the flywheel in conjunction with the brake lever. A brake wire extending from the brake lever and is branched into two brake wires, one connected to the drum brake, and the other connected to the rotational sensor.

Abstract: To realize a light steering handle operation similar to that of a real bicycle, and to obtain an appearance similar to that of a real bicycle. A bicycle simulation system has a turnable steering handle, a left-right pair of pedals, a frame for turnably supporting the steering handle and the pedals, a monitor for displaying a scenery according to the simulated running velocity required by a first speed pickup, a controller supplying sensor signals to a main control unit which controls the monitor. The controller is provided on front forks that function as a front stand.

Abstract: A gas exhaust structure of a fuel-cell-powered vehicle includes a recess formed in a rear bumper with a surrounding wall. An opening of the recess is covered with louvers to allow ventilation, thereby to form a chamber. A discharge end of the discharge pipe is mounted to the chamber. An exhaust gas including hydrogen is guided through the discharge pipe into the chamber and is emitted from the opening to the outside of the vehicle.

Abstract: A hydrogen ventilation duct includes tubes for communication between a motor room as a space beneath a hood and a space inside a gutter. The gutter includes a vent communicating with the outside. Hydrogen staying in the motor room is released naturally through the tubes into the atmosphere.
