Fig. 7～Fig. 9 shows other embodiment of rotary electrical unit of the present invention.At this moment, different with the structure of Fig. 1～the foregoing description illustrated in fig. 6 points are different this point of a structure part of operating axis.In addition, for at the parts that Fig. 1～the foregoing description illustrated in fig. 6 is identical, mark identical symbol and omit its explanation.
Among the figure, operating axis, the first axle body 3 that is made of metal material that is zine pressure casting is identical with the structure of Fig. 2, the foregoing description illustrated in fig. 3, but for cooperate with this first axle body 3 by the auxiliary section, to the structure of the outstanding the second axle body 17 of the foreign side of parts of bearings 4, different on a part.
At this moment, the second axle body 17 is to form by the soft material that is made of identical synthetic resin material, and it has: knob installation portion 17a, and it forms roughly cylindric and has the plane that D cuts shape in one side; Cooperate and use protuberance 17b, it has thin slightly diameter distolateral the giving prominence to of this knob installation portion 17a; And insert axial region 17c, its this cooperation with protuberance 17b one distolateral with strip give prominence to, have thinner diameter.In addition, in the present embodiment, the second axle body 17 is also formed by the synthetic resin material with light transmission.
In addition, at the outer peripheral face that cooperates with protuberance 17b,, be formed with outstanding a pair of locking protrusion 17d, 17d to foreign side in diametric relative position.This locking protrusion 17d is by cooperating with the stop hole 3f of the first axle body 3, and cooperates the first axle body 3 and the second axle body 17 integratedly.
The first axle body 3 and the second axle body 17 cooperate with recess 3c with the cooperation that protuberance 17b is embedded into the first axle body 3 that becomes embedded hole portion by the cooperation with the second axle body 17, thereby are cooperated by one.At this moment, because the second axle body 17 is formed by soft synthetic resin material, therefore be arranged at locking protrusion 17d, the 17d deformable ground that cooperates the outer peripheral face of using protuberance 17b and cooperate and use recess 3c to cooperate.
And this locking protrusion 17d, 17d are matched with stop hole 3f, the 3f that cooperates with recess 3c by buckle-type, and the first axle body 3 cooperates with the second axle body 17 one.And the axial region 3b of the first axle body 3 rotatably inserts and leads in the cylindrical portion 4b of parts of bearings 4, by the knob installation portion 17a of rotary manipulation the second axle body 17, thereby can one install rotatably with respect to parts of bearings 4.
So, the first axle body 3 and the second axle body 17 utilize the elasticity that the second axle body 17 had that is made of the synthetic resin material and are cooperated by buckle-type, can make two axis bodies integrated simply, and can the one rotation.In addition, because of excessive impact load, the second axle body 17 bendings, or can easily come off, therefore, when having applied excessive load, can easily untie both cooperations.
In addition, the first axle body 3 and the second axle body 17 are engaged near the portion of root unit that the foreign side of parts of bearings 4 gives prominence at the axial region 3b of the first axle body 3, and the mutual cooperation position of the first axle body 3 and the second axle body 17 is positioned near the leading section of parts of bearings 4.And when operating axis had been applied excessive load, because this load acts near the leading section of parts of bearings 4, so the second axle body 17 bent easily, comes off from the first axle body 3.
In addition, when the first axle body 3 and the second axle body 17 are cooperated by one by stop hole 3f and locking protrusion 17d, the insertion axial region 17c of the strip of the second axle body 17 inserted lead in through hole 3g, described through hole 3g is with continuous and connect on axis direction with recess 3c as cooperating of the embedded hole portion of the first axle body 3.And, the front end that inserts axial region 17c extends to the roughly the same position of front end with the chimeric teat 3d of the first axle body 3, the front end of this insertion axial region 17c is disposed at relatively in the rear of rotary electrical unit luminous element disposed 11, constitutes the light guide section that guiding comes the light of self-emission device 11 from inserting axial region 17c front end up to the front end of the knob installation portion 17a of the second axle body 17.
So, in the present embodiment, synthetic resin material by light transmission forms the second axle body 17, and the insertion axial region 17c of the second axle body 17 inserted lead in the through hole 3g that on the axis direction of the first axle body 3, connects, the front end of this insertion axial region 17c is extended the rear that is set to fixed part 1, can will should insert axial region 17c itself thus as light conductor, therefore, therefore more light can be directed to effectively the front end of operating axis (the second axle body 17), operation knob 14 effectively can also lead the light that is configured in the LED (light-emitting component 11) etc. at the rear of rotary electrical unit.
In addition, in the above-described embodiments, though the structure that forms is, the first axle body 3 and the second axle body 5,17 form respectively independently, stop hole 3f, 3f by being arranged at auxiliary section separately and locking protrusion 5c, 5c, 17d, 17d buckle-type cooperate and form an operating axis, but therewith differently, also can both are integrally formed with embedding method such as shaping, operating axis of formation under the state that the first axle body 3 has cooperated with the second axle body 5,17.
