Description

The present invention relates to the field of bars and levers.

  Japanese Patent No. 2785127 (bar and lever) is disclosed as a conventional bar and lever.

  The pipe bodies 3 and 3a constituting the bar and lever bar of the above disclosure are substantially elliptical in cross section in the direction in which the opening portions 35 and 36 on both the left and right sides are orthogonal to each other.

  Further, as described above, in the pipe body of the bar and lever bar disclosed above, the section of the pipe between the openings on both the left and right sides has a circular shape.

  Therefore, when working in a state such as a bar, the pipe body has a circular shape even when wearing gloves, so it has a drawback that it is slippery and difficult to slip even if it is gripped. .

Therefore, workability was not so good.
