PROBLEM TO BE SOLVED: To make electrolyte solution leak effectively delayed at leaning of a battery, without making a battery cover of a dual structure. SOLUTION: An exhaust cap 36 including a first vertical hole 40 communicated with an exhaust hole 38, a spiral path 42 and a second vertical hole 44 is built into exhausted paths 16, 16' of a battery cover 14 in liquid tightness. Also, electrolyte solution is made not to move from one place to another by blocking the exhausted paths 16, 16' with a built-in block body 24 having a parting wall in the middle of the exhausted paths 16, 16'. This way, a large resistance can be shown to a leak of the electrolyte solution, therefore, an acid leak of a battery for a vehicle having a tendency to lean by receiving a big vibration can be prevented effectively. |
