Rotary tool

Abstract

A rotary tool includes a first longitudinal member, a second longitudinal member disposed across a region of a rod-shaped brush, a first elastic between the first longitudinal member and the second longitudinal member, and for causing the rod-shaped brush to rotate with a turn of the first longitudinal member, and a turn of the second longitudinal member, and a second elastic between the first longitudinal member and the second longitudinal member, and attached to the first and second longitudinal members. The first elastic is located on one side and the second elastic is located on the other side, regarding a boundary of a first axis or a second axis.

What is claimed is: 
     
         1 . A rotary tool comprising:
 a first longitudinal member that is turnable in forward and reverse directions about a first axis substantially perpendicular to a plane on which a to-be-rotated body is disposed;   a second longitudinal member that is turnable in forward and reverse directions about a second axis that is substantially parallel to or substantially the same as the first axis of turning of the first longitudinal member, and opposed to the first longitudinal member across a region in which a to-be-rotated body is disposed;   rotating means disposed between the first longitudinal member and the second longitudinal member, and for causing a to-be-rotated body to rotate with a turn of the first longitudinal member and a turn of the second longitudinal member;   an elastic member disposed between the first longitudinal member and the second longitudinal member, and attached to the first longitudinal member and the second longitudinal member; and   a rod-shaped to-be-rotated body to be caused to rotate by the rotating means, and having a plurality of projection portions at at least one end, wherein   the rotating means is located on one side with respect to a boundary of the first axis or the second axis in a region between the first longitudinal member and the second longitudinal member,   the elastic member is located on the other side with respect to a boundary of the first axis or the second axis in a region between the first longitudinal member and the second longitudinal member,   the first longitudinal member and the second longitudinal member turn so that the distance between each other's end portions present at the same side with respect to a boundary of the first axis or the second axis varies,   the rotating means is a first elastic that is attached to the first longitudinal member and the second longitudinal member, and wound around the to-be-rotated body,   the elastic member is a second elastic that is attached to the first longitudinal member and the second longitudinal member, and attached to the to-be-rotated body to be windable therearound,   a first longitudinal member at a side where a second elastic is attached with respect to a boundary of the first axis is provided with a first finger hole to pass through fingers or a thumb, and   a second longitudinal member at a side where a second elastic is attached with respect to a boundary of the second axis is provided with a second finger hole to pass through fingers or a thumb.   
     
     
         2 . The rotary tool according to  claim 1 , comprising a turning support to which the first longitudinal member and the second longitudinal member are turnably attached and in which a through-hole is provided, wherein
 the to-be-rotated body is inserted through the through-hole.
