Abstract
A liquid quantity visual confirmation device comprises a first reservoir-forming member, and a second reservoir-forming member forming a liquid reservoir in combination with the first reservoir-forming member. The second reservoir-forming member is at least partially transparent to allow visual confirmation of the internal liquid level from an outside thereof. The second reservoir-forming member has a liquid-feeding port for feeding the liquid into the liquid reservoir. The quantity of liquid in the liquid reservoir can be confirmed by looking at the internal liquid level in the second reservoir-forming member from the outside. It is also possible to reliably feed the liquid into the liquid reservoir from the liquid-feeding port while confirming any rising of the liquid level through the transparent portion.
