Abstract: The invention relates to a light vehicle such as a golf caddie which includes a body and at least two wheels that are respectively connected to the body by first and second axles. The axles can be pivoted in a first position in which they are tilted against the body and in a second position in which they extend away from the body, where the second position is defined as the driving position of the vehicle. At least one spring acts on the body and on the axles, maintaining the driving position of the axles only by the elastic force thereof, without additional transversal supports and bracing.

Abstract: A gas generator for an air bag, in which conduction of heat generated by combustion of a gas generating agent is restricted to effectively reduce or inhibit a temperature increase of a diffuser side on an outer shell container, is provided and thus, reduces the maximum surface temperature of the diffuser. The gas generator includes a housing which has a diffuser shell with at least one gas discharge port and a closure shell for forming an accommodating space together with the diffuser shell and the gas generating agent, installed in the housing, ignited and burnt by an igniting unit to generate a combustion gas, wherein the gas generator further includes a heat transfer restricting member for making a conduction of heat generated by a combustion of the gas generating agent to the diffuser shell side smaller than that to the closure shell side.
