PROBLEM TO BE SOLVED: To enable suppression of leakage of droplet V in a lead-acid battery.SOLUTION: A lead-acid battery 10 includes a power generation element 30, an electrolytic solution W, a battery container 20 for housing the power generation element 30 and the electrolytic solution W, and a lid member 50 which seals the battery tank 20 and has an exhaust space R intercommunicating with the outside and a cylindrical member T for making the exhaust space R intercommunicate with the inside of the battery tank 20. The bottom surface of the exhaust space R is inclined so as to reflux the fluid in the space into the battery container 20. The cylindrical member T has two shielding bodies 84B, 84D which are arranged to be spaced from each other in the extension direction of the cylindrical member T, and makes the inside of the battery container 20 and the exhaust space R intercommunicate with each other through the gap between the two shielding bodies 84B, 84D.SELECTED DRAWING: Figure 10 |
