PROBLEM TO BE SOLVED: To use parts of a reservoir tank having difference in a position of a liquid pouring plug in common. SOLUTION: The inside of a tank body 11 constituted of a lower case 11a and an upper case 11b is partitioned by a partitioning wall 12; a liquid level detection chamber 13 is formed in a separable manner; filters 14 and 24, a float 15, a liquid level sensor 16, and a partitioning plate 17 for restricting flow-in/out of working liquid (a) are provided in the lower case of the tank body; and the liquid pouring plug 18 is provided on the upper case. Two or more kinds of the upper case 11b having different liquid poring plug position is covered on the lower case 11a and the abutting faces can be joined. Thus, when the liquid level sensor is provided in the lower case, only the profile of the liquid pouring plug is different in the upper case, the upper case having different profiles of the liquid pouring plug is joined to the lower case having the profile corresponding to the respective profile, and several kinds of the reservoir tanks having different position and profile of the liquid poring plug can be achieved by the lower case of one profile.
