<P>PROBLEM TO BE SOLVED: To provide a rotation auxiliary assembly capable of improving operability. <P>SOLUTION: A rotation auxiliary assembly 4 comprises base portions (a first base portion 46, a second base portion 47, a third base portion 50, and a forth base portion 49), and grip portions (a first grip portion 43, a second grip portion 44, and a third grip portion 45). The base portion is wound around a rotation adjusting member in a rotating direction of the rotation adjusting member. The grip portion is coupled with the base portion in a rotating direction, and a user touches the grip portion with a finger when rotating the rotation adjusting member. First maximum dimensions (L1, L2, L3) measured from a rotation center of the rotation adjusting member to an outside surface in a radial direction of the rotation adjusting member of the grip portion are larger than a second maximum dimension (L0) measured from the rotation center to the outside surface in the radial direction of the base portion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
