Patent attributes
A reservoir capable of shortening a time period required to fill a brake system and a clutch system with a fluid with vacuuming in a case where the reservoir has a brake reservoir chamber to be connected to a brake master cylinder of the brake system and a clutch reservoir chamber to be connected to a clutch master cylinder of the clutch system. The reservoir (12) includes a brake reservoir chamber (28) and an inlet port for injecting the brake reservoir chamber (28) with a fluid from outside. The reservoir further includes a clutch reservoir chamber (29) separated from the brake reservoir chamber (28), and a communication passage (37) providing communication between the inlet port and the brake reservoir chamber (28). The communication passage is branched so as to communicate with the clutch reservoir chamber (29).
