Then, utilize Fig. 2, Fig. 4, Fig. 5 (a)～(b) that joint 4 is elaborated.As shown in Figure 4, second articulated section 29 that is contained in joint 4 is made up of rotating shaft members 41, holding member 42, cam part 43, first spring members 44, cartridge unit 45, flat member 46, back-up ring 47, moving member 48 and second spring members 49.With this second articulated section 29 in abutting connection with dispose the assembly (bearing part or mobile control division) 50 that can not be installed on lower frame body 3 rotationally.
Rotating shaft members 41 has: the arm 54 that small diameter part 51, the slot part 52 that is formed at small diameter part 51, diameter form greater than the large diameter part 53 of small diameter part 51, with the mode with large diameter part 53 quadratures, be formed at arm 54 and be fixed in the first screw hole portion 57 and the second screw hole portion 58 of upper frame body 2 and first through hole 59 that connects small diameter part 51 and large diameter part 53 by screw 55 and 56.Large diameter part 53 has breach face 60 (with reference to Fig. 6).Large diameter part 53 is formed between small diameter part 51 and the arm 54.
Holding member 42 has: keep and support second through hole 61 and the 3rd through hole 62 of the small diameter part 51 of rotating shaft members 41, the accommodation section 63 of accommodating and keeping moving member 48, the 3rd screw division 64, first jut 65, second jut 66 rotationally.The cam part installed with the mode of together rotating with small diameter part 51 43, first spring members 44, cartridge unit 45, flat member 46 are installed at the small diameter part that passes second through hole 61 51 places.Thereafter, large diameter part 53 and holding member 42 butts, rotating shaft members 41 is positioned with respect to holding member 42, makes the front end of small diameter part 51 not connect the 3rd through hole 62 of holding member 42.
At slot part 52 back-up ring 47 is installed, thereby rotating shaft members 41 is rotatably installed on holding member 42.And rotating shaft members 41 is retained as and does not break away from holding member 42.
Cam part 43 is the parts that when rotating shaft members 41 is rotated, produce click.Therefore, be arranged at the axial direction of small diameter part 51 rotationally.The opposition side that is formed with concavo-convex first male and fomale(M&F), 67, the first male and fomale(M&F)s 67 in a side is by first spring members, 44 application of forces.With first male and fomale(M&F), 67 opposed holding members 42 on also be formed with the second concavo-convex male and fomale(M&F) 68.When cam part 43 and rotating shaft members 41 together when the relative state of concave surface of the convex surface of first male and fomale(M&F) 67 and second male and fomale(M&F) 68 rotates; The convex surface of first male and fomale(M&F) 67 breaks away from from the state relative with the concave surface of second male and fomale(M&F) 68, and the convex surface of the convex surface of first male and fomale(M&F) 67 and second male and fomale(M&F) 68 is relative.When breaking away from, the deflection of first spring members 44 increases, and produces click.In addition, when the relative state of convex surface from the convex surface of first male and fomale(M&F) 67 and second male and fomale(M&F) 68 becomes the concave surface of convex surface and second male and fomale(M&F) 68 of first male and fomale(M&F) 67 when relative, the deflection of first spring members 44 reduces, and produces click.
That is, when rotating shaft members 41 is rotated,, can feel click when rotating needed torque when changing sharp.The position that produces click constitutes: when beginning to the second open mode transition from closed state and when the transition of second open mode finishes, produce.The user can be when carrying out the transition to second open mode and when transition begins from closed state and transition feel click when finishing.In addition, when the transition when second open mode carries out the transition to closed state and transition also can feel click when finishing.
The bight 44A that flat member 46 is arranged to make the belleville spring that constitutes first spring members 44 not with back-up ring 47 direct butts.In addition, flat member 46 has hole 69, and small diameter part 51 is inserted and led in this hole 69.
The bight 44A of belleville spring is the circle shape, and back-up ring 47 has the opening portion 70 that is cut off, and therefore, the bight 44A that can avoid belleville spring comes off and inclination etc. do not produce the deflection of regulation at opening portion 70.
Utilize Fig. 5 (a)～(b) that the effect of flat member 46 is described here.Shown in Fig. 5 (a) owing to have a flat member 46, therefore first spring members 44, be configured to apart from the full week of the bight 44A of the internal side diameter of the nearest belleville spring of back-up ring 47 and the first tabular surface 46A butt of flat member 46.Even be configured under the situation nearest apart from back-up ring 47 at bight 44B with the outside diameter of belleville spring, full week of bight 44A also with the first tabular surface 46A butt of flat member 46.On the other hand, shown in Fig. 5 (b), when not having flat member 46, opening portion 70 first spring members 44, that be configured to then be trapped in back-up ring 47 apart from the part of the bight 44A of the internal side diameter of the nearest belleville spring of back-up ring 47.Therefore, shown in Fig. 5 (b), cause belleville spring to tilt.If belleville spring tilts, then many pieces of deflections that overlapping first spring members 44 that forms does not produce regulation.Therefore, can be with the load of regulation to cam part 43 application of forces, the cam part 43 that therefore together rotates with rotating shaft members 41 does not produce the slip torque of regulation and desired click.
Thereby, because second articulated section 29 is provided with flat member 46, the deflection that therefore produces regulation through first spring members 44; Can on rotating shaft members 41, produce stable torque etc.; Can not lose the stability of the torque of generation, can fluctuation be minimized on the one hand, can realize miniaturization on the one hand.
In addition; If first spring members 44 is stressed and vertically bear the active force that first spring members 44 produces with respect to the face of first spring members, 44 sides of back-up ring 47; Then can produce the deflection of regulation etc. at first spring members, 44 places, also can suitably between first spring members and back-up ring 47, append and make towards the side of first spring members, 44 sides and the part all parallel with back-up ring 47 towards the side of back-up ring 47 sides.
The first par 46A of flat member 46, with the promptly parallel second par 46B in the back side of the first par 46A with the first par 46A in abutting connection with and the back-up ring 47 of butt, that groove 52 that back-up ring 47 is installed promptly is positioned at the opposing face of first male and fomale(M&F) 67 of end face 52A and cam part 43 in a distant place with respect to first spring members 44 is all parallel, and vertical with the axle center b of rotating shaft members 41.Therefore, first spring members 44, be configured to apart from the bight 44A and the first tabular surface 46A butt of the internal side diameter of the nearest belleville spring of back-up ring 47, therefore the reaction force of first spring members 44 can act on the axial direction of small diameter part 51.Thereby the active force that first spring members 44 is produced vertically acts on the opposing face of the end face 52A and first male and fomale(M&F) 67 (b is parallel with the axle center).
If the back side and the end face 52A of first male and fomale(M&F) 67 meet at right angles with respect to axle center b; Promptly the back side of the first par 46A and first male and fomale(M&F) 67 all is set as the plane with the bight butt of first spring members 44; And between flat member 46 and back-up ring 47, be provided with the part of the active force that transmits spring; Then first spring members 44 produces the active force of regulation, and rotating shaft members 41 is rotated with the regulation torque, and cam part 43 produces desired click.
In addition; As stated; First spring members 44, be configured to must contact with flat member 46 apart from the bight 44A of the internal side diameter of the nearest belleville spring of back-up ring 47, so hole 69 must consider also that with respect to the gap (shake allowance) of the profile of small diameter part 51 assembling sets.That is, be preferably, suitably set for: even shake allowance is maximum, also can be effectively with first spring members 44, be configured to apart from the bight 44A butt of the internal side diameter of the nearest belleville spring of back-up ring 47.
When back-up ring 47 when the distortion that opening portion 70 is enlarged is installed on slot part 52, the deflection that first spring members 44 only produces established amount, and to cam part 43 towards holding member 42 application of forces.
That is, while when the distortion that opening portion 70 is enlarged when back-up ring 47 was installed on slot part 52, holding member 42 kept with the mode that cam part 43, first spring members 44, back-up ring 47 and flat member 46 are clipped in the middle.Not so-called cantilever position, but the two end supports state.Thus, holding member 42 can strengthen the maintenance length L 1 that keeps small diameter part 51 (the illustrated back side from first male and fomale(M&F) 67 is to the length of end face 52A among Fig. 2), so rotating shaft members 41 reduces with respect to the vibration of holding member 42.

Bearing part 50 is arranged to across lower frame body 3 and joint 4, and is mounted to fixingly with respect to lower frame body 3, and can rotate with respect to joint 4.Bearing part 50 has the 4th through hole 75 and the hook portion 76 that is formed at forward end, hook portion 76 when main part is first open mode with foot's 73 butts, make moving member 48 courts arrow C side shifting in the opposite direction shown in Figure 4.
Then, utilize Fig. 6 that joint 4 is described.One distolateral (side of joint 4 is installed) of lower frame body 3, (being left end side among Fig. 6) is formed with and is the cylindraceous first hinged assembly department 77 substantially in the end, is formed with at the cardinal principle central part to be guide portion 78 cylindraceous substantially.
Joint 4 is made up of first holding part 79, second holding part 80 and the joint 81 that connects first holding part 79 and second holding part 80.First holding part 79 is disposed between the first hinged assembly department 77 and the guide portion 78.
Joint 81 is disposed at the outside of guide portion 78, and forms, and first holding part 79 and second holding part 80 sandwich it from the outside of guide portion 78.Has the second hinged assembly department 82 that second articulated section 29 is installed in the inside of joint 81.For the second hinged assembly department 82, it is with respect to joint 4, is front end with the 3rd screw division 64 of second articulated section 29, and along main part 1 assembling towards the direction of lower frame body 3 sides from upper frame body 2 sides during for closed state.After second articulated section 29 was contained in the joint 4, screw 83 and the 3rd screw division 64 screwed togather fixing.

Fig. 7 is identical with symbol shown in Figure 6 to symbol shown in Figure 9, therefore omits the symbol description of Fig. 7 to Fig. 9.In addition, cable assembly 32 constitutes by many, but in Fig. 7 to Fig. 9, concentrates to be illustrated as a cable.
Then, utilize Fig. 2 and Figure 10 (a)～(b) that cable 32 is described.Among Fig. 2, cable 32 constitutes by many.Though not shown, cable 32 be by a plurality of Central conductors, be arranged at the outside of Central conductor first isolation layer, be arranged at first isolation layer the outside external conductor and be arranged at the coaxial fine rule that second isolation layer of the outside of external conductor constitutes.Many cable 32 is inserted and is led in the pipe part 33 that hollow shape ground forms.Pipe part 33 forms with the fibrage that is made up of polyester etc.For sectional shape can easily be out of shape, and the surface all possesses low frictional properties with inner face, so formed by lamination coating.
For example, the situation that is formed pipe part 33 by rubber material is described.When opening and closing main part 1, pipe part 33 and other constituent parts (first through hole 59 of the inner face of joint 4 and rotating shaft members 41 etc.) on every side rub, and are prone to produce wearing and tearing.At this moment, the skin friction resistance of rubber material is big, therefore when rubbing, produces wearing and tearing, causes the hole to be opened.Therefore, the common boundary belt of around rubber tubulation parts, reeling.Consequently, being prone to cause cost rises.
The state configuration that pipe part 33 is inserted the cable 32 be connected with many with hollow parts is in first through hole 59.One of pipe part 33 distolaterally is directed in the upper frame body 2 after first through hole 59 breaks away from.Another of pipe part 33 is distolateral to break away from roughly 90 degree of rear curved one-tenth from first through hole 59, and the 4th through hole 75 that passes bearing part 50 then is directed to lower frame body 3 sides.Bend at many cables 32 near the position of 90 degree, for example, the bindings such as adhesive tape of the cable 32 usefulness cementabilities of Ruo Duogen, then the many cable 32 after the binding is not flexible, and the result is to cause the curvature R that forms to become big.Even curvature R is big,, also must strengthen the distance L 2 of the inner face 4A from first through hole 59 to joint 4, so the result is to strengthen joint 4 and main part 1 integral body for the many cable 32 after will bundling is configured in the joint 4.
Therefore, in this mode of execution, can only be not with many cable 32 sheaves insert and lead in pipe part 33.Therefore, shown in Figure 10 (a), many cable 32 is arranged substantially in first through hole 59 roundedly and is gone forward side by side.Pipe part 33 also is configured to lineal shape.Here, when the diameter with pipe part 33 was made as D, the diameter of pipe part 33 was than the big (relation of D＞L2) of the distance L from the first above-mentioned through hole 59 to the inner face 4A of joint 42.In addition, just after first through hole 59 breaks away from, pass the space of the distance L 2 of the inner face 4A from first through hole 59 to joint 4 at many cables 32, therefore, shown in Figure 10 (b), cable assembly 32 is ovalizes substantially.Pipe part 33 also is deformed into oval substantially.The minor axis side of pipe part 33 equates with distance L 2 basically.
As stated, many cable 32 is arranged in the deformable pipe part 33 in cross section, after bending to 90 degree, is disposed in the space than the narrower of pipe part 33 curvature that generates in the time of therefore can reducing bending.Thereby, can reduce the distribution space, therefore can avoid the maximization of main part 1.
Then, utilize Fig. 1 (a)～(d) that the action of the open and close type portable phone of mode of execution is described.The user is according to using model selection closed state (Fig. 1 (a)), first open mode (Fig. 1 (b)), second open mode (Fig. 1 (c)).
When to main part 1 energized, begin to receive the wait action.Through operation unit 14 is operated, can switch to camera mode and TV receiving mode.
Under camera mode, the starting through second camera section 15 comes switch mode.When making the starting of second camera section 15, can the photographic images of second camera section 15 be shown in first display unit 7, preserve under the situation of pinch image pattern picture wanting, can be stored in information storage part 25.
Under the TV receiving mode, play if receive TV, then can carry out TV and watch at first display unit 7.The TV image is the picture of growing crosswise, and therefore is preferably, and picture is watched to grow crosswise.In this case; With respect to lower frame body 3; Is that open along the arrow B direction at the center with upper frame body 2 with the axle center b shown in Fig. 1 (c), thereby main part 1 is set as second open mode, when operation unit 14 being remained on nearby side; As the picture of growing crosswise, become the form that to see that suitable TV such as first display unit, 7 grades watches.
In addition, when under each pattern, incoming call being arranged, in order to notify incoming call, from loudspeaker 6 output incoming sound.At this moment, upper frame body 2 is rotated along the A direction shown in Fig. 1 (b), main part 1 is set as first open mode, when the operation of stipulating, can hard to bear words.User's sound is from microphone 13 outputs.
When finished call, the pattern before beginning once more to be talked about.
When portable, be preferably closed state.
Action when then, utilizing Fig. 6 that main part 1 is opened and closed describes.In Fig. 6, because main part 1 is a closed state, so the hook portion 76 of bearing part 50 and foot's 73 butts of moving member 48, make moving member 48 courts and the opposite direction of arrow C direction (with reference to Fig. 4) move (in Fig. 6, the paper depth direction).In Fig. 6, moving member 48 demonstrates the state that buries in accommodation section 63.The protuberance 72 of the moving member 48 not breach face 60 with the large diameter part 53 of rotating shaft members 41 is relative, so rotating shaft members 41 can be that rotate along arrow B direction shown in Figure 6 at the center with axle center b.
Then, utilize Fig. 7, Fig. 8 to describe with the axle center b action that to be the center rotate each parts when becoming second open mode shown in Fig. 1 (c) along the arrow B direction with respect to lower frame body 3 from the closed state shown in Fig. 1 (a) to making upper frame body 2.Fig. 7 representes that rotating shaft members 41 is about 170 degree have been rotated at the center along the arrow B direction state (second open mode) from the state (closed state) of Fig. 6 with axle center b.The large diameter part 53 of rotating shaft members 41 pass moving member 48 protuberance 72 forward end and become second open mode.Through breach face 60 and first jut, 65 butts that are formed at holding member 42, can only rotate the angle (being 170 degree) of established amount in this mode of execution.Under second open mode, large diameter part 53 covers protuberance 72 front ends of moving member 48.
That is, the hook portion 76 of bearing part 50 and foot's 73 butts of moving member 48, the active force of bearing part 50 opposings second spring members 49 moves moving member 48 courts and arrow C direction in the opposite direction, thereby with in the protuberance 72 introducing accommodation sections 63.And the large diameter part 53 of rotating shaft members 41 constitutes with the mode of the arrow C side front end of the protuberance 72 of covering moving member 48.
Here, Fig. 8 is the partial enlarged drawing of Fig. 7.In Fig. 8, under second open mode, large diameter part 53 covers the part (fore-end) of the protuberance 72 of moving member 48, representes the position that is capped with the 72A of oblique line portion.
Then, utilize Fig. 9 that the action of bearing part 50 is described.Fig. 9 represent with make upper frame body 2 from state shown in Figure 6 (closed state) with respect to lower frame body 3 with axle center b be the center not towards the arrow B direction rotate make upper frame body 2 with respect to lower frame body 3 with axle center a be state after rotate towards the arrow A direction at the center identical, lower frame body 3 is the state after center court rotates with arrow A direction in the opposite direction with respect to upper frame body 2 with axle center a.
Because bearing part 50 can remain in second holding part 80 with respect to joint 4 rotationally in the guide portion 78 that can not remain in lower frame body 3 rotationally; Therefore when upper frame body 2 be the center when the arrow A direction is rotated predetermined angular with respect to lower frame body 3 with axle center a, bearing part 50 is the center court direction rotation predetermined angular in the opposite direction with arrow A with respect to joint 4 with axle center a.Consequently, the hook portion 76 of bearing part 50 is away from foot 73.Bearing part 50 away from after moving member 48 active force through second spring members 49,42 outstanding directions move towards protuberance 72 from holding member.Protuberance 72 and breach face 60 butts after outstanding, so upper frame body 2 is not that rotate towards the arrow B direction at the center with axle center b.
That is, bearing part 50 is to resist active force that first spring members 49 produced and the parts that the position of moving member 48 is controlled according to the framework form of main part 1.Therefore in addition, protuberance 72 and second jut, 66 adjacency are center court when rotating with arrow B direction in the opposite direction when having a mind to and by mistake making upper frame body 2 with axle center b, protuberance 72 and breach face 60 and the equal butt of second jut, 66 both sides.At this moment, when with bigger power butt, can cause protuberance 72 to damage, therefore adopt the structure of protuberance 72 and second jut, 66 butts, even feasiblely also do not damage from breach face 60 is stressed.
That is, protuberance 72 produces moment of flexure so that 63 outstanding states when stressed, become so-called overhang state from breach face 60 from the accommodation section.Even if also do not damage protuberance 72, can strengthen moving member 48 or use the big material of allowable stress, but from another point of view, can cause and maximizing and the cost rising for moment of flexure is played a role.
Therefore, in this mode of execution, the opposing face and second jut, 66 butts of the stress surface through making moving member 48 can not produce moment of flexure, have therefore avoided the maximization of moving member 48, cost to rise.That is the power that, puts on protuberance 72 replaces to the power of compression from the power of bending.Because the material of compression power is very abundant, so moving member 48 can be made up of versatile material.
Then, utilize Fig. 1 (d) that the 3rd open mode of main part 1 is described.Having carried out making upper frame body 2 the user is that the hook portion 76 of bearing part 50 is away from the foot 73 of moving member 48 under the situation of the center misoperation of rotating towards the arrow A direction with axle center a with respect to lower frame body 3 from second open mode shown in Fig. 1 (c).When away from the time, through the application of force of second spring members 49, moving member 48 will move towards the arrow C direction, but because the part (fore-end) of moving member 48 is in the state that is covered by large diameter part 53, therefore can not move towards the arrow C direction.The fore-end of supposing moving member 48 is not covered by large diameter part 53, and then moving member 48 moves towards the arrow C direction.As the form of main part 1, it is a upper frame body 2 with respect to lower frame body 3 state after A direction and B direction are rotated simultaneously, and the form of the main part 1 shown in Fig. 1 (d) is called the 3rd open mode.Under the 3rd open mode, therefore first display unit 7 can not see the demonstration information that is shown in display unit 7 not towards user's side.Therefore, the user is in order to remove the 3rd open mode, upper frame body 2 rotated with respect to the opposition side of arbitrary direction of lower frame body 3 in A direction and the B direction get final product.Make upper frame body 2 with respect to lower frame body 3 structure of rotating of the arbitrary direction in A direction and B direction only if adopt, then the user sometimes by error towards the direction that can not rotate firmly can cause main part 1 to damage.
Of this mode of execution; Under the 3rd open mode; Because moving member 48 is covered by large diameter part 53, moving member 48 can not move towards outstanding direction, therefore; If making upper frame body 2 be center court with arrow A in the opposite direction direction and with axle center b with respect to lower frame body 3 with axle center a from the 3rd open mode is that center court rotates with the arbitrary direction the arrow B direction in the opposite direction, the arbitrary state of the change of form that then can make main part 1 in first open mode or second open mode.If be set as first open mode, then moving member 50 moves, and protuberance 72 is outstanding, as stated, and protuberance 72 and breach face 60 butts after giving prominence to, so upper frame body 2 can not be that rotate towards the arrow B direction at the center with axle center b with respect to lower frame body 3.Thereby, can not hold shape and return to the 3rd open mode from second.
Know that by above holding member 42 adopts to grow to distance L 1 to greatest extent the small diameter part 51 of rotating shaft members 41 is remained on the structure in the joint 4, therefore can reduce the shake allowance with respect to rotating shaft members 41.Even under the situation of the outside application of force,, therefore also can reduce the increase degree of shake allowance owing to keep with long distance L 1.
In addition, under first open mode, become moving member 48 outstanding and with the state of large diameter part 53 butts, even therefore wanting to make upper frame body 2 is that rotate towards the arrow B direction at the center with axle center b, can not rotate.And, under closed state, want to make upper frame body 2 with under the axle center b situation that to be the center rotate towards the arrow B direction, can carry out simply.To main part 1; Following user's main part 1 easy to use can be provided: when the user has been set as the 3rd open mode by error; Can easily become any state in first open mode or second open mode; When being set as first open mode, prevent to the 3rd open mode variation etc.
Promptly; In second articulated section 29, be provided with moving member 48 with the state interlock of main part 1; Make the form of main part 1 not change to the 3rd open mode from first open mode; Therefore with first open mode upper frame body 2 is contacted with head and when conversing, upper frame body can not run counter to user's intention and rotate the user.
In addition,, therefore can save the space in distribution space, avoid the maximization of main part 1 because upper frame body 2 and the many cable 32 that lower frame body 3 is electrically connected are disposed at the deformable pipe part 33 in cross section.
In addition, when pipe part 33 not being set, second isolation layer directly contacts with first through hole 59 of second articulated section 29.When rotating shaft members 41 was rotated, first through hole 59 and second isolation layer produced friction, at this moment, cause sometimes external conductor is exposed.Generally speaking, second articulated section 29 requires to have high rigidity, is therefore formed by metallic material.Therefore, if external conductor exposes, then rotating shaft members 41 and external conductor short circuit might together be delivered to Central conductor as noise again with signal.For fear of this situation, be preferably formed second isolation layer, but from another point of view, can cause cable 32 not flexible with desirable thickness.Consequently, must strengthen the internal diameter and the L2 of first through hole 59.Therefore, be preferably, realize the miniaturization of second articulated section 29, on this basis,, can not use by the bunch of adhesive tape binding 32 slotting leading to of cable in pipe part 33 for cable 32 through the pathization of saving spatialization, first through hole 59.
In addition; In this mode of execution; When main part 1 is closed state; The control of having carried out making bearing part 50 and moving member 48 butts and the opposite direction of moving member court and arrow C being moved, but also can make the part that is fixed in lower frame body 3 or the part of lower frame body 3 replace bearing part 50 to control the position of moving member 48.
In addition, second spring members 49 of this mode of execution is made up of pressure spring, and when main part 1 was closed state, the elastic force of resisting second spring members 49 moved the moving member 48 courts direction opposite with arrow C, but is not limited to this.For example, constitute second spring members 49 by extension spring, direction protuberance 72 courts are opposite with arrow C with the power of extension spring stretches.Also can be when main part 1 be the closed state and second open mode, the part of bearing part 50 and lower frame body 3 opposing elastic force makes moving member 48 move towards the arrow C direction.
In addition, adopted moving member 48 to carry out the structure of so-called translational motion, but be not limited to this.For example, also can possess running shaft, and be that move through rotatablely moving at the center, when making it carry out when primary importance not with the rotating shaft members butt and the limit rotation of rotating shaft members butt in the second place with the running shaft.
In addition, not to being elaborated around the back-up ring 47, for example, make under the situation that main part falls down in user mistake, causing back-up ring 47 to break away from such impact force from slot part 52 can play a role.The such state of affairs of imagination can be provided with towards the stiffening rib of back-up ring 47 peripheries in joint 4 etc., so that the opening portion 70 of back-up ring 41 does not enlarge.
In addition, above-mentioned bight all is illustrated as the right angle, but on part is made, even produced the part on curved surface and plane, also can adopt to make with the structure of one edge with respect to the first tabular surface 46A butt.
In addition, the structure that large diameter part and rotating shaft members is made as one is illustrated, but also other parts can be installed and constitute.
