Remote lock operation apparatus for light vehicle

The invention allows, in a light vehicle having no cabin, to cover, even if only one Infrared receiver of a remote lock operation apparatus is used only by one for one vehicle in order to reduce the burden to a battery, the range of directivity of the Infrared receiver required for a light vehicle of the type described readily without being influenced by a seat or a vehicle body. To achieve this, a single Infrared receiver (R) is disposed at an uppermost portion of a vehicle body.
