TECHNICAL FIELD The present invention relates to a fixing structure for attaching a shield electric wire to a shield shell and a fixing method for the shield electric wire. BACKGROUND ART In the shield electric wire used for a power feeder or a wiring of various kinds of vehicles such as a hybrid vehicle, as a shield connector attached to a terminal end thereof, for instance, a shield connector disclosed in Patent Literature 1 is known. Namely, the shield connector is used in the wiring of an electric system of the vehicle. The shield connector 100 includes, as shown in FIG. 13 , a connector terminal 120 connected to a terminal end part of a shield electric wire 110 having a core wire 111 , a braided part 112 and a sheath 113 , a connector case 130 for protecting and accommodating the terminal end part of the shield electric wire 110 , a corrugation holder 140 attached to an electric wire inserting side of the connector case 130 , a corrugated tube 180 for protecting the shield wire that is connected to the electric wire inserting side of the connector case 130 through the corrugation holder 140 . The corrugation holder 140 is formed with a pair of opposed half covers. The connector case 130 of the above-described members includes an outer case 150 made of a synthetic resin and an inner case 160 similarly made of a synthetic resin and both the cases are cylindrical bodies having both ends opened. Both the outer case 150 and the inner case 160 are plated with electrically conductive metal. A lance 170 is provided to be fixed and locked to a mating connector not shown in the drawing. According to the shield connector 100 having the above-described structure, a production cost can be reduced and a misalignment of the sheath 113 in the shield electric wire 110 or the like can be prevented, however, only an individual shield electric wire can be connected thereto. Accordingly, depending on the difference of kinds of shield electric wires for vehicles on which the shield electric wires are respectively mounted or the difference of shield processes for vehicles on which the shield electric wires are respectively mounted (namely, the difference between an individual shield process and a collective shield process or the like), the shield connector is not occasionally applicable. Thus, as the shield connector, a shield connector disclosed in Patent Literature 2 is also proposed. Namely, this shield connector is a wire harness side shield connector 200 that is fitted and connected to an inverter unit side connector 300 as shown in FIG. 14 and FIG. 15 . The wire harness side shield connector 200 includes an outer case 210 having a shield function and a housing 220 that accommodates connecting terminals respectively bonded under thermal compression and fixed to end parts of a plurality of shield electric wires 230 . The outer case 210 includes a shield shell 211 that has a shield function for shielding and grounding an electromagnetic wave and accommodates the housing 220 and a shell holder 213 that is fixed to the shield shell 211 by a screw member 212 to electrically conduct braided parts 231 of the shield electric wires 230 folded to an outer peripheral side respectively to the shield shell 211 . On the other hand, the inverter unit side connector 300 includes a resin mold housing 310 , an electrically conductive body 320 and an electrically conductive cover 330 attached so as to sandwich the electrically conductive body 320 , and is directly connected to an inverter which is not shown in the drawing. According to the above-described shield connector 200 , the shield connector can easily and assuredly meet the difference of the kinds of the shield electric wires for each of the vehicles or the difference of the electromagnetic shield processes for each of the vehicles (namely, the difference between then individual shield process and the collective shield process or the like). CITATION LIST Patent Literature Patent Literature 1: JP-A-11-26093 Patent Literature 2: JP-A-2007-115428 SUMMARY OF INVENTION Technical Problem In the shield connector 200 disclosed in the Patent Literature 2, a structure for fixing the terminal end parts of the braided parts 231 of the shield electric wires 230 to the shield connector 200 is complicated, and when the screw member 212 is loosen, the attached state of the shield shell 211 and the shell holder 213 that are attached integrally is put out.

DESCRIPTION OF EMBODIMENTS Now, an exemplary embodiment of the present invention will be described in detail below by referring to the attached drawings. FIGS. 1 to 3 show a fixing structure 10 of a shield electric wire according to the exemplary embodiment of the present invention. The fixing structure 10 of the shield electric wire includes a shield electric wire 20 , a shield ring 30 , a shield shell 40 and an inner holder 50 (In FIG. 3 , the shield ring 30 is shown under a state before the shield ring is clamped). The shield electric wire 20 includes a core wire 24 in a central part, an insulating coat 21 formed with an insulator such as an insulating resin with which an outer periphery of the core wire 24 is coated, an electrically conductive braided part 22 provided in the outer periphery of the insulating coat 21 and an insulating sheath 23 with which an outer side of the braided part 22 is coated. The shield electric wire 20 of this exemplary embodiment has a structure that core wires of two cores are shielded together. However, a shield electric wire may be used that has a structure in which core wires of a single core or three or more cores are shielded together. The braided part 22 has a folded part 22 A (see FIG. 3 ) formed previously by folding an end part inside (or outside) by a prescribed length. The shield ring 30 is formed with a thin metal material having a prescribed strength in a hollow cylindrical shape. The shield electric wire 20 passes through a ring shaped inner part of the shield ring 30 . When the shield ring 30 is attached to the shield electric wire 20 and the shield shell 40 , in the ring shaped inner part thereof, the core wire 24 and the insulating coat 21 of the shield electric wire 20 , a part of the shield shell 40 (a below-described small diameter part 41 ), the folded part 22 A of the braided part 22 of the shield electric wire 20 peeled off from the core wire 24 and the insulating coat 21 and the shield ring 30 are arranged in this order outward in the radial direction. Especially, a part of the shield shell 40 (the below-described small diameter part 41 ) and the folded part 22 A are arranged to be laminated. As shown in FIGS. 4 and 5 , the shield shell 40 includes the small diameter part 41 having the hollow cylindrical shape, a main body part 42 connected to one end of the small diameter part 41 and a support piece 43 attached to the main body part 42 . The small diameter part 41 is arranged relative to the shield electric wire 20 so that the core wire 24 and the insulating coat 21 of the shield electric wire 20 passes through the hollow part thereof and the folded part 22 A of the braided part 22 covers a tubular outer side surface (an outer periphery). Further, the small diameter part 41 is arranged under a state that the small diameter part 41 passes through the shield ring 30 . The shield ring 30 having the ring shaped inner part in which the small diameter part 41 is located is arranged so as to cover the outer side surface of the folded part 22 A of the braided part 22 . The small diameter part 41 has an inside diameter larger than the outside diameter (the outside diameter in the direction of a long diameter) of the insulating coat 21 of the two cores of the shield electric wire 20 and an outside diameter smaller than the inside diameter of the shield ring 30 . Further, the small diameter part 41 is passed through by a sleeve of the below-described inner holder 50 . The main body part 42 has a hollow tubular form and the inner holder 50 is accommodated therein. The main body part 42 has one side to which the small diameter part 41 is connected and the other side opened to insert the inner holder 50 . The main body part 42 is formed in a hollow quadratic prism shape and includes four wall surfaces facing the insulating coat 21 of the shield electric wire 20 passing through the main body part 42 . Further, boundary parts for connecting the wall surfaces respectively form round shaped curved surfaces, so that an entire part of an outer periphery of the main body part shows a seamless form. Further, the outer form of the main body part 42 is larger than the outside diameter of the small diameter part 41 , so that a stepped part is formed in a connecting part of the main body part 42 and the small diameter part 41 . Further, in the main body part 42 , a lance engaging part 421 is formed with which a lance 53 of the below-described inner holder 50 is engaged on one surface of the four wall surfaces. The lance engaging part 421 is formed by cutting inward the main body part 42 a tongue piece 423 facing a groove 422 formed substantially in a U shape. The above-described forms of the small diameter part 41 and the main body part 42 can be formed by a drawing press. Since the main body part is formed by the drawing press, the main body part is formed without seams. In other word, the main body can be formed under a state that a fragile part does not exist in a part thereof. The main body 42 is not necessarily formed in a hollow quadratic prism shape, and may be formed in a cylindrical shape or in a polygonal column having three or five surfaces or more. The support piece 43 secures the shield electric wire 20 fixed by the fixing structure of the present invention to a part (for instance, a vehicle panel) of a vehicle not shown in the drawing and a slot 431 is formed which is attached to a stud bolt protruding from the vehicle panel. The support piece 43 of the present exemplary embodiment is extended from an end part of one wall surface of the main body part 42 , and is bent at 90° relative to the main body part 42 so as to be parallel to the one surface having the lance engaging part 421 . The inner holder 50 is inserted into and fixed to an inner part of the above-described main body part 42 of the shield shell 40 from an opposite side to a side in which the small diameter part 41 is provided under a state that the inner holder 50 is passed through by the core wire 24 and the insulating coat 21 of the shield electric wire 20 . The inner holder 50 is formed with a semi-cylindrical part with a substantially U shaped form in section divided by a slit 55 (see FIGS. 1 to 3 ) in one side, and divided parts are integrally connected together by a connecting part 541 (see FIG. 3 ) in a base end part side. The inner holder 50 includes, as shown in FIGS. 2A and 2B , inserting parts 52 facing outer peripheral surfaces of an upper part and a lower part of the insulating coat 21 , a half divided part 51 extended from an end of the inserting part 52 located in an upper side and attached in close contact with the outer peripheral surface of the upper part of the insulating coat 21 , the lance 53 formed in a cantilever support state in the upper side of the inserting part 52 and engaged with the lance engaging part 421 of the shield shell 40 and cut-off wall parts 54 respectively formed in upper sides and lower sides of the inserting parts 52 to prevent the entry of water drops from the upper part of the insulating coat 21 . The inner holder 50 is fixed to the shield shell 40 under a state that the core wire 24 and the insulating coat 21 of the shield electric wire 20 are inserted into an electric wire holding hole formed in a sleeve formed by the half divided part 51 and the inserting parts 52 and the sleeve passes through the small diameter part 41 of the shield shell 40 . At this time, since the cut-off walls 54 located in the outer periphery of the inner holder 50 are located more outside than the outside diameter of the sleeve formed by the inserting part 52 , stepped parts are formed between the cut-off walls 54 and the inserting parts 52 . Thus, the stepped parts abut on the stepped part in the connecting part of the main body part 42 and the small diameter part 41 of the shield shell 40 to regulate the insertion of the inner holder 50 into the shield shell 40 . Now, operational effects of the fixing structure of the shield electric wire of the present invention will be described. According to the fixing structure 10 of the shield electric wire of the present exemplary embodiment, as shown in FIGS. 5A to 5C , the main body part 42 of the shield shell 40 (a substantially cylindrical part) is formed by the drawing press, so that the main body part 42 is formed substantially in a box shape surrounded by an outer peripheral surface including four surfaces. In other words, since the main body part 42 has the outer peripheral surface with a four-surface structure having no seams over an entire periphery, not only the tensile strength is increased, but also the structure of the main body does not have a partial unevenness in strength and has a uniform strength over the entire periphery. Accordingly, when the shield ring 30 is clamped to the small diameter part 41 extending integrally with the main body part 42 and pressed to the braided part 22 of the shield electric wire 20 , even if a physical tension due to the clamping operation is transmitted to the main body part 42 so that the main body part 42 is apt to be pulled toward the small diameter part 41 , the main body part 42 whose strength is increased can meet the tensile stress during the clamping process. Thus, the main body part 42 can be prevented from being pulled toward the small diameter part 41 and deformed. Especially, one surface (an upper surface in FIG. 6A ) of the main body part 42 can hold a surface state parallel to the axial direction of the main body part 42 (the shield electric wire 20 ). Namely, as shown in FIG. 6B , the tongue piece 423 having the lance engaging part 421 of the main body part of the shield shell 40 is not pulled to be inclined relative to the axial direction of the main body part 42 (the shield electric wire 20 ). Accordingly, an engagement margin between the lance engaging part 421 of the main body part of the shield shell 40 and a pawl part 531 of the lance 53 of the inner holder 50 can be sufficiently ensured to realize a strong and assured connected state. A fixing structure 90 shown in FIG. 8A may be considered. In the fixing structure 90 , a shield shell 60 of FIG. 7 is used instead of the shield shell 40 as described above. In the case of the fixing structure 90 of the shield electric wire shown in FIG. 8A , which uses the shield shell 60 having a main body part 62 connected to a small diameter part 61 and bent substantially in a U shape in section as shown in FIG. 7 , the main body part 62 includes only two upper and lower surfaces ( 62 A, 62 B). That is, right and left surfaces are not included as compared with the shield shell 40 of FIG. 4 . Since the main body part 62 of this form is lower in its anti-tensile strength than the main body part 42 of the shield shell 40 of FIG. 4 , when a physical tensile stress is applied to the main body part 62 during a clamping operation, the main body part is pulled toward the small diameter part 61 (leftward in FIG. 8A ), so that the form of the main body part may be changed. As a result, there is a fear that an inner holder 50 may be more hardly assuredly fitted to the shield shell 60 than in the fixing structure 10 of the shield electric wire of the present invention. Further, in the fixing structure 90 whose form is changed, as shown in FIG. 8B , an inconvenience occurs that an upper surface 62 A of the small diameter part 61 side is pulled so that an opening side is greatly opened, and an engaging pawl 621 of a lance engaging part is inclined at an angle θ so as to be lower toward the small diameter 61 side so that an engagement margin to a pawl part 531 of a lance 53 of the inner holder 50 is reduced to make an engaged state unstable. Therefore, there is a fear that the inner holder 50 may slip out from the shield shell 60 . However, since the shield shell 60 in FIG. 7 has a form in which the right and left surfaces are omitted as compared with the structure of the shield shell 40 , it is possible to reduce the weight and material cost. Thus, in such a case where the fixing structure does not require the strict design to have a high anti-tensile strength, the shield shell 60 can be applied to form the fixing structure 90 . Now, a fixing method for the shield electric wire to the shield shell according to the present invention will be described below. (1) Initially, as shown in FIG. 9 , the sheath 23 is cut by a prescribed length from one end of the shield electric wire 20 to expose the braided part 22 . Further, the braided part 22 is peeled off from the insulating coat 21 that covers the core wire 24 . One end side of the peeled braided part 22 is expanded in a tapered form as shown in FIGS. 1 and 2 and an area of a prescribed length from the terminal end of the braided part 22 is folded outside (or inside) to form a folded part 22 A. (2) Then, the shield electric wire 20 passing the process (1) is inserted into the shield ring 30 , the small diameter part 41 and the main body part 42 of the shield shell 40 . The order of the process (1) and the process (2) may be reverse. (3) Then, in the folded part 22 A of the braided part 22 of the shield electric wire 20 , the shield ring 30 is arranged so as to cover the outer periphery of the folded part 22 A as shown in FIG. 3 . The shield ring 30 and the shield shell 40 are moved relatively to the shield electric wire 20 so that the small diameter part 41 of the shield shell 40 is located in the inner part of the folded part 22 A. Thus, the core wire 24 of the shield electric wire 20 , the insulating coat 21 , the small diameter part 41 of the shield shell 40 , the folded part 22 A of the braided part 22 of the shield electric wire 20 and the shield ring 30 are laminated in this order from an inner side to an outer side. (4) Then, in a part (a clamping target part) in which the small diameter part 41 of the shield shell 40 , the folded part 22 A of the braided part 22 of the shield electric wire 20 and the shield ring 30 are laminated, clamping dies 70 A and 70 B are set so as to hold the clamping target part from upper and lower parts as shown in FIG. 10 . (5) Subsequently, a core 80 is internally inserted so that the small diameter part 41 of the shield shell 40 forming an innermost layer of the clamping target part is internally inserted. Then, as shown in FIG. 10 , the clamping dies 70 A and 70 B are fastened to clamp the clamping target part. The core 80 has a hollow tubular form whose outside diameter substantially corresponds to the inside diameter of the small diameter part 41 of the shield shell 40 and the insulating coat 21 of the shield electric wire passes through the inner part of the core 80 . The core 80 has a high rigidity. Thus, when the clamping dies 70 A and 70 B are fastened to clamp the shield ring 30 to the small diameter part 41 , the core 80 pushes back the small diameter part 41 from an inner side to an external force. The deformation of the small diameter part 41 due to the clamping process of the shield ring 30 can be prevented. (6) After the above-described clamping operation is completed, as shown in FIG. 11 , the clamping dies 70 A and 70 B are removed and the core 80 is separated. (7) Finally, as shown in FIG. 12 , the half divided part 51 of the inner holder 50 is attached to the outer surface of a half circumference of the insulating coat 21 of the shield electric wire 20 and the half divided part 51 is moved along the insulating coat 21 to insert the inner holder 50 to a part where the end of the half divided part 51 passes the small diameter part 41 of the shield shell 40 and reaches a prescribed position, namely, the lance 53 is engaged with the lance engaging part 421 of the shield shell 40 . At this time, the half divided part 51 and the insulating coat 21 exposed from the inner holder 50 in a lower side of the half divided part 51 may be wound in the circumferential direction by a tape to fix the insulating coat 21 and the core wire 24 to the inner holder and the inner holder 50 may be inserted under the fixed state. According to the above described fixing structure of the shield electric wire and the fixing method for the shield electric wire of the present invention, even when during the clamping operation of the shield ring 30 , a fastening force is exerted on the small diameter part 41 of the shield shell 40 so that the fastening force is transmitted to the main body part 42 of the shield shell, the distortion or deformation of the outer configuration of the main body part 42 of the shield shell 40 can be prevented. As a result, the engaged state of the shield shell 40 and the inner holder 50 is not unfastened so that an assured holding force may be ensured and a space may be avoided from being formed between the shield electric wire 20 or the inner holder 50 and the shield shell in accordance with the deformation of the shield shell 40 .
