ABSTRACT:
A filler cap of a jar for a washer is provided with a stopper portion plugging filler hole of the jar, a pawl portion engaged with the filler hole and a tubular gauge for measuring residual quantity of detergent liquid in the jar which extends toward the bottom of the jar. The tubular guage communicates with an air hole in the cap opening on a finger gripped face of a knob provided on the stopper portion. In using this filler cap, it is possible to measure the residual quantity of the detergent liquid with ease and accuracy since gripping the knob to remove the stopper portion of the cap will also cover the air hole so as to retain a quantity of liquid in the guage indicative of the amount of fluid left in the jar.
