Abstract: A reservoir tank includes a reservoir body defining a storage chamber for an operating fluid; and a float guide in the storage chamber. The float guide forms a float chamber on the inner side. The reservoir tank further includes a fluid level detection device that has a float moving up and down in the float chamber in accordance with fluctuations of a fluid level, and has a detector detecting when the float is below predetermined position. The reservoir tank is provided with a slit in the float guide. The slit is in communication with the storage chamber and the float chamber. An operating fluid passage is provided on an inner face of the float guide which is continuous with the slit, which is in communication with the slit and the float chamber.

Abstract: A reserve tank is fixed to the vehicle body with a bracket. The bracket includes a supporting member supporting an intermediate part which is an intermediate part in vertical direction when the reserve tank is fixed to the vehicle body side. The supporting member includes the vertical movement restricting part for restricting a vertical movement while the reserve tank is fixed to the vehicle. The reserve tank includes the fastening part fastened with the fastening member to a fastened part formed on the bracket, the rotation restricting part for restricting, at a location apart from the fastening part, rotation on the fastening part, and an extending part protruding outwardly in a diametrical direction from a side surface of the reserve tank and extending from a side of the fastening part in a circumferential direction to the rotation restricting part.
