In this occasion, in Figure 12 (a) shown in double dot dash line, if two hairbrush 127b ' that will be located at the cross section and be on the major diameter of stator 122 of substantially elliptical shape set shortly, then two hairbrush 127b ' can be contained in the height dimension H1 of motor accommodating chamber 13, but two hairbrush 127b ' with hairbrush 127b reduced in comparison this size, can't realize the long lifetime of hairbrush 127b '.
Relative therewith, in the present embodiment, shown in Figure 12 (a), on the diagonal of the substantially elliptical shape of stator 122, because the substantially elliptical shape that the structure that adopts is the outer circumference side edge face 127c of each hairbrush 127b to be positioned at than stator 122 leans on outer circumferential side, and, dispose the structure of two hairbrush 127b in the quadrangle T that connects in the substantially elliptical shape than stator 122 (quadrangle of representing with double dot dash line in the scheming) mode of inner all sides, therefore two hairbrush 127b former state ground with length identical with above-mentioned comparative example (Figure 12 (b)) motor 120 can be used for, thereby the long lifetime of hairbrush 127b can be realized, and even the long lifetime of motor 120.
In addition, hairbrush portion 127 is not limited to be provided with two, also can be provided with four accordingly with four jiaos of the quadrangle T that connects in the substantially elliptical shape of stator 122.
If go on to say referring again to Fig. 8, then cap assembly 125 is the covers that are installed in as described above on the step surface 123c of bonnet 123, is formed by rubber-like insulating elements such as synthetic rubber.During from end on observation, the part corresponding with hairbrush portion 127 (only illustrating a side in Fig. 8) is outstanding diametrically in the cap assembly 125, thus, above 125c become with respect to the face vertical with the side 125a of top 125c adjacency.Similarly, 125d becomes with respect to the face vertical with the side 125b of following 125d adjacency below.That is to say that cap assembly 125 has top 125c, side 125a, following 125d and the side 125b for mutual vertical relation.
In addition, be formed with peristome 125e in the bottom surface of cap assembly 125,125e draws from motor lead with substrate 123b by this peristome.
