ABSTRACT:
A device for indicating the level of liquid contents remaining in a tank which has a viewing portion through which the side of a synthetic resin tank is exposed. The viewing portion is formed around a cap and in the vicinity of an opening of the tank which can be seen through and which is held by a tank holding member, such that the opening of the tank has a dimension which is larger than that of the cap so that the level of the fuel can be viewed through the annular viewing portion formed thereby.
