Battery terminal stopper and battery terminal unit

Abstract

A battery terminal unit includes a battery terminal that is assembled on a battery post and also includes a battery terminal stopper. The battery terminal stopper includes a first rotation preventing portion that abuts against a first abutment surface formed on a side surface of a battery housing in a state where the battery terminal is assembled on the battery post so as to be able to restrict rotation of the battery terminal about the battery post as the rotating center. The battery terminal stopper also includes a second rotation preventing portion that abuts against a second abutment surface formed on the battery housing along a direction intersecting with the first abutment surface in the assembled state so as to be able to restrict rotation of the battery terminal about the battery post as the rotating center.

What is claimed is: 
     
         1 . A battery terminal stopper comprising:
 an attachment portion capable of being attached to a battery terminal that is assembled on a battery post provided on a battery housing;   a first rotation preventing portion configured to be provided on the attachment portion, oppose a first abutment surface formed on a side surface of the battery housing, and abut against the first abutment surface in a state where the battery terminal is assembled on the battery post together with the attachment portion so as to be able to restrict rotation of the battery terminal about the battery post as a rotating center; and   a second rotation preventing portion configured to be provided on the attachment portion, oppose a second abutment surface formed on the battery housing along a direction intersecting with the first abutment surface, and abut against the second abutment surface in the state where the battery terminal is assembled on the battery post together with the attachment portion so as to be able to restrict rotation of the battery terminal about the battery post as the rotating center.   
     
     
         2 . The battery terminal stopper according to  claim 1 , wherein
 the second abutment surface is formed on a wall surface of a recess that is formed on a post stand surface provided with the battery post and on which the battery post is provided upright in the battery housing, the wall surface being orthogonal to the side surface of the battery housing on which the first abutment surface is formed.   
     
     
         3 . The battery terminal stopper according to  claim 1 , wherein
 the second abutment surface is formed on a side surface of the battery housing that is orthogonal to the side surface of the battery housing on which the first abutment surface is formed.   
     
     
         4 . The battery terminal stopper according to  claim 1 , wherein
 the first rotation preventing portion and the second rotation preventing portion are formed integrally with the attachment portion, and   the attachment portion is interposed between the battery terminal and the battery housing in a state where the battery terminal is assembled on the battery post together with the attachment portion.   
     
     
         5 . The battery terminal stopper according to  claim 2 , wherein
 the first rotation preventing portion and the second rotation preventing portion are formed integrally with the attachment portion, and   the attachment portion is interposed between the battery terminal and the battery housing in a state where the battery terminal is assembled on the battery post together with the attachment portion.   
     
     
         6 . The battery terminal stopper according to  claim 3 , wherein
 the first rotation preventing portion and the second rotation preventing portion are formed integrally with the attachment portion, and   the attachment portion is interposed between the battery terminal and the battery housing in a state where the battery terminal is assembled on the battery post together with the attachment portion.   
     
     
         7 . A battery terminal unit comprising:
 a battery terminal configured to be assembled on a battery post provided on a battery housing; and   a battery terminal stopper configured to include an attachment portion capable of being attached to the battery terminal, a first rotation preventing portion that is provided on the attachment portion, opposes a first abutment surface formed on a side surface of the battery housing and abuts against the first abutment surface in a state where the battery terminal is assembled on the battery post together with the attachment portion so as to be able to restrict rotation of the battery terminal about the battery post as a rotating center, and a second rotation preventing portion that is provided on the attachment portion, opposes a second abutment surface formed on the battery housing along a direction intersecting with the first abutment surface and abuts against the second abutment surface in the state where the battery terminal is assembled on the battery post together with the attachment portion so as to be able to restrict rotation of the battery terminal about the battery post as the rotating center.
