The inner cable 2 has one cable end 21 at one end and the other cable end (not shown) at the other end. One of the one cable end 21 and the other cable end is connected to an operation unit (not shown) for operating the inner cable 2, and the other is operated via the inner cable 2 by operation of the operation unit. Connected to an operated portion (not shown).

The outer casing 3 has an insertion path 31 (see FIG. 2), and the inner cable 2 is inserted through the insertion path 31. The outer casing 3 is routed in at least a part of the routing path from the operation portion to the operated portion, and guides the inner cable 2 inserted into the insertion passage 31.

As shown in FIGS. 1 to 3, the terminal member 4 is attached to the end portion (one end 32) of the outer casing 3, and the control cable 1 is attached to an attachment object B (FIG. 1 and FIG. 1) via the terminal member 4. 2). In addition, although the terminal member 4 is attached to the one end 32 side of the outer casing 3, the terminal member 4 may be attached also to the other end side of the outer casing 3 which is not illustrated.

1 to 3, the terminal member 4 includes an attachment portion 41 attached to the attachment object B and a holding portion 42 that holds the outer casing 3. In this embodiment, as shown in FIG. 1 and FIG. 2, the attachment object B is shown as a plate-like bracket, and the attachment portion 41 is engaged with a notch N formed in the bracket, so that the terminal The member 4 is attached to the attachment object B. In the present embodiment, as shown in FIGS. 1 to 3, the attachment portion 41 is provided on the

end portions

41a and 41b on both sides in the insertion direction of the inner cable 2 (hereinafter referred to as the axial direction) and the

end portions

41a and 41b. It has the narrow part 41c which was pinched | interposed and became narrow with respect to

edge part

41a, 41b. The terminal member 4 can be attached to the attachment object B by inserting the narrow part 41c into the notch part N and sandwiching the plate-like attachment object B between the

end parts

41a and 41b. The shape of the attachment portion 41 is not particularly limited as long as it can be attached to the attachment object B, and the cross section perpendicular to the axial direction of the

end portions

41a, 41b and the narrow portion 41c is circular or other shapes. It may be.

As shown in FIGS. 2 and 3, the attachment portion 41 is provided with a communication portion C through which the inner cable 2 is inserted. The communication part C is formed so as to penetrate the attachment part 41, and a first opening O1 and a second opening O2 are formed at both ends of the communication part C, respectively. In the communication portion C, a central portion M is formed between the first opening O1 and the second opening O2, and the first opening O1, the central portion M, and the second opening O2 1 Two passages are formed. The first opening O1 is open on one end side of the attachment portion 41 (on the right end portion 41a side in FIG. 2) facing the holding portion 42 side. The second opening O2 opens on the opposite side (cable end 21 side) to the first opening O1 on the other end side of the attachment portion 41 (on the left end portion 41b side in FIG. 2). . In addition, the 1st opening part O1 and the 2nd opening part O2 do not say only the opening edge in the both ends of the attachment part 41 in this specification, but say the site | part which has predetermined length in an axial direction. .

The inner diameter of at least one of the first and second openings O1 and O2 may be reduced toward the center of the communication part C. In the present embodiment, as shown in FIGS. 2 and 3, the inner diameters of both the first opening O1 and the second opening O2 are reduced toward the center of the communication part C. In this embodiment, as FIG. 2 and FIG. 3 show, the 1st opening part O1 becomes the insertion part Is into which the edge part 32 of the outer casing 3 mentioned later is inserted. Since the inner diameter of the first opening O1 is reduced toward the center of the communication part C, the end 32 of the outer casing 3 is press-fitted into the first opening O1, and the end 32 is fixed. Becomes stronger. Further, as shown in FIGS. 2 and 3, the second opening O <b> 2 has an inner diameter that decreases toward the center of the communication portion C. As a result, the opening width becomes wide at the opening edge of the second opening O2, the inner cable 2 can be easily inserted, and the inner cable 2 can be shaken during operation (for example, the inner cable 2 in the vertical direction in FIG. 2). (Runout) is allowed. In addition, when the control cable 1 is swung, it is possible to suppress a load caused by the contact of the inner cable 2 with the opening edge of the second opening O2. As described above, in the present embodiment, the outer casing 3 is fixed to the terminal member 4 at two locations of the first opening O1 and a holding portion 42 described later. Each of the first opening O1 and the second opening O2 may have the same inner diameter in the axial direction. In the present embodiment, the central portion M is shown as having an inner diameter that does not change in the axial direction, but the inner diameter may be changed in the axial direction. Further, in the present embodiment, the communication part C is composed of a plurality of parts (first opening O1, second opening O2, and center part M) having different diameters in the axial direction. The part C is not limited to the shape shown in the figure, and may have the same diameter from one end side to the other end side of the attachment part 41.

Further, the terminal member 4 has a holding portion 42 for holding the one end 32 side of the outer casing 3 as shown in FIGS. In the present embodiment, the holding portion 42 is connected to the attachment portion 41 in the axial direction via the connection portion 43 as shown in FIGS. Although the connection part 43 is not necessarily an essential structure, it is preferable that the connection part 43 is provided between the attachment part 41 and the holding part 42. As a result, a gap can be provided between the attachment portion 41 and the holding portion 42, and the deformation of the holding portion 42 is hindered by the attachment portion 41 as compared with the case where the holding portion 42 is connected to the attachment portion 41. Therefore, the holding portion 42 is easily elastically deformed. The shape of the connecting portion 43 is such that a space is provided between a portion of the holding portion 42 that is elastically deformed for holding the outer casing 3 and the mounting portion 41 so that the holding portion 42 can be elastically deformed. If it can connect with the holding | maintenance part 42, it will not specifically limit. In the present embodiment, the connection portion 43 is inserted in the outer casing 3 in which at least a part in the circumferential direction is inserted into the insertion portion Is of the mounting portion 41, for example, a cross section perpendicular to the axial direction is substantially C-shaped. It is also an open shape so that can be confirmed. Thereby, the insertion state of the outer casing 3 can be easily confirmed from the outside, and maintenance such as elimination of a defect in the insertion state is facilitated. The connecting portion 43 is formed in a flat plate shape in the present embodiment, and is disposed at a symmetrical position with respect to the slit S described later around the axis of the holding portion 42, and the mounting portion 41 and the connecting portion 43 are connected to each other. Connected.

The holding portion 42 holds the one end 32 side of the outer casing 3 with an elastic force so that the communicating portion C and the insertion path 31 are substantially coaxial. As shown in FIGS. 1 to 3, the holding portion 42 has an introduction path 42a for the outer casing 3 therein, and when the outer casing 3 is inserted through the introduction path 42a, the outer circumferential side of the outer casing 3 is provided. The outer casing 3 is held by elastic force. If the material of the holding | maintenance part 42 can be elastically deformed, the material will not be specifically limited, For example, it forms with a synthetic resin, a metal, etc. The holding portion 42 has, for example, an inner diameter equal to or smaller than the outer diameter of the outer casing 3 in order to hold the one end 32 side of the outer casing 3 with an elastic force, and as shown in FIG. The outer casing 3 is held so that 3 is substantially linear. As a result, the outer periphery on the one end 32 side of the outer casing 3 spreads the holding portion 42, the outer casing 3 is firmly held by the elastic force that is the reaction force, and the outer casing 3 is unlikely to come off the holding portion 42. In the present embodiment, as shown in FIG. 4, the holding portion 42 has a shape (in FIG. 4, a circle) whose inner surface shape is similar to the outer shape of the outer casing 3, and extends along the axial direction of the holding portion 42. The slit S is provided. More specifically, in the present embodiment, as shown in FIG. 3, the holding portion 42 has a holding portion side first opening 42 b and a holding portion side second opening at both ends in the axial direction of the substantially cylindrical holding portion 42. The slit S is formed along the axial direction from the holding part side first opening 42b to the holding part side second opening 42c. As shown in FIG. 4, the interval between the slits S is configured to be narrower than the outer diameter of the outer casing 3 (or the inner diameter of the introduction path 42a). In the present embodiment, the outer casing 3 is arranged along the slit S, and the outer casing 3 by pushing the outer casing 3 toward the slit S can be inserted into the holding portion 42. The slit S is configured. When the outer casing 3 is attached to the holding portion 42, the holding portion 42 is elastically deformed so that the interval between the slits S is widened, and after the outer casing 3 is attached, the restoring force ( The outer casing 3 is held by elastic force. When the holding part 42 has the slit S, it becomes easy to absorb the outer diameter change due to the difference in the type of the outer casing 3 and the dimensional tolerance of the outer casing 3 and the holding part 42. In the present embodiment, the slit peripheral edge portions Sa and Sb along the slit S of the holding portion 42 have an opening width of the slit S that becomes wider toward the radially outer side of the holding portion 42 in order to make the slit S easier to spread. Is so curved. The shape of the holding portion 42 is not particularly limited as long as it can be elastically deformed and can hold the one end 32 side of the outer casing 3 by elastic force. For example, a plurality of slits may be provided, You may form in the cylindrical shape in which the slit is not provided.

Here, at the opening edge of the holding portion side first opening 42b of the holding portion 42, in this embodiment, as shown in FIG. 3, a tapered portion T whose inner diameter becomes wider toward the end face side of the holding portion 42. Is formed. Thereby, for example, as will be described later, when the outer casing 3 is inserted and attached from the end face side (holding portion side first opening 42b) of the holding portion 42, the outer casing 3 is easily attached. Further, when the outer casing 3 is inserted from the end face side of the holding portion 42, the attachment operation to the insertion portion Is is only in the axial direction of the holding portion 42, so that the outer casing 3 can be easily assembled.

2 and 3, the terminal member 4 is provided on the holding portion 42 side of the mounting portion 41, and the insertion portion Is into which the one end 32 of the outer casing 3 held by the holding portion 42 is inserted. have. The insertion portion Is is formed as a recess having a depth in the axial direction of the mounting portion 41 into which the one end 32 of the outer casing 3 can be inserted. In the present embodiment, the first opening O1 is connected to the insertion portion Is. It has become. When the one end 32 of the outer casing 3 is inserted into the insertion portion Is such as the first opening O1, the communication portion C without bringing the inner cable 2 led out from the outer casing 3 into contact with other external members. Through the second opening O2 of the terminal member 4. The width (inner diameter) of the inner peripheral surface of the insertion portion Is is preferably substantially the same as the outer diameter of the one end 32 of the outer casing 3 or smaller than the outer diameter of the outer casing 3 so that it can be press-fitted. As long as the outer casing 3 does not rattle, the size may be such that a slight gap is generated between the outer casing 3 and the outer periphery.

In the present embodiment, the insertion portion Is has a shape in which the cross section of the inner peripheral surface is circular, but the shape of the insertion portion Is is not limited as long as one end 32 of the outer casing 3 can be inserted. In the present embodiment, the insertion portion Is is shown as the first opening O1, but the insertion portion Is may be provided separately from the first opening O1, for example, one end 32 of the outer casing 3. May be an annular recess provided on the radially outer side of the opening edge of the first opening O1. In the present embodiment, the insertion portion Is (first opening O1) has an inner peripheral surface that is reduced in diameter toward the center of the communication portion C, as shown in FIGS. Accordingly, the one end 32 of the outer casing 3 is press-fitted into the insertion portion Is, whereby the one end 32 of the outer casing 3 can be more firmly fixed.

When the one end 32 of the outer casing 3 is inserted into the insertion portion Is, the movement of the one end 32 of the outer casing 3 is restricted. Therefore, in the terminal member 4 of the present embodiment, the one end 32 side of the outer casing 3 is attached to and held by the holding portion 42, and further inserted into the insertion portion Is, so that 2 of the holding portion 42 and the insertion portion Is. Held in place. For this reason, even when the outer casing 3 moves, such as when the inner cable 2 is operated or when an external force is applied to the outer casing 3, the outer casing 3 is unlikely to come off the terminal member 4. Further, in the present embodiment, the one end 32 side of the outer casing 3 is held by the elastic force of the holding portion 42, and the one end 32 of the outer casing 3 is simply inserted into the insertion portion Is, and the outer casing 3 is connected to the terminal member 4. Installation is complete. Therefore, it is easy to attach the outer casing 3 to the terminal member 4. Usually, when attaching the outer casing 3 to the terminal member 4, it is easy to come off if the attachment is simplified, and if it is difficult to remove, the attaching operation becomes complicated. In this embodiment, however, the attachment of the outer casing 3 to the terminal member 4 is difficult. Both ease and difficulty of detachment can be achieved.

Next, with reference to FIG. 1 and FIG. 2, an example of the assembly of the control cable 1 of the present embodiment to the attachment target B and the operation effect will be described.

As shown in FIG. 1, the inner cable 2 inserted through the outer casing 3 is passed through the terminal member 4, and the one end 32 side of the outer casing 3 is attached to the holding portion 42. For example, as shown in FIG. 1, the outer casing 3 is arranged coaxially with the holding portion 42 and is pushed in from the holding portion side first opening 42 b side. Alternatively, the outer circumferential surface of the outer casing 3 may be pressed against the slit peripheral portions Sa and Sb of the holding portion 42 and the outer casing 3 may be pushed in while the slit S is widened.

Next, in a state where the outer casing 3 is held by the elastic force of the holding portion 42, the outer casing 3 is further pushed toward the insertion portion Is, and one end 32 of the outer casing 3 is inserted into the insertion portion Is. In the present embodiment, the insertion portion Is (first opening O1) is reduced in diameter toward the center of the communication portion C, and one end 32 of the outer casing 3 is press-fitted into the insertion portion Is and firmly fixed. The Here, in the present embodiment, the inner peripheral surface of the holding portion 42 is smooth, and there is no unevenness in the axial direction from the holding portion side first opening 42b to the holding portion side second opening 42c, and the outer casing 3 has the holding portion 42. It is only held by the elastic force. Therefore, there is little resistance at the time of insertion in the insertion part Is, and pushing of the outer casing 3 is easy. Further, when inserting the one end 32 of the outer casing 3 into the insertion portion Is, the outer casing 3 is aligned with the center of the insertion portion Is by the holding portion 42, so when the flexible outer casing 3 is press-fitted, It can be easily press-fitted.

When one end 32 of the outer casing 3 is inserted into the insertion portion Is, the attachment portion 41 is attached to the cutout portion N of the attachment object B as shown in FIG. 2, and the cable end 21 of the inner cable 2 is not shown. At this point, the control cable 1 is attached to the attachment object B.

After the control cable 1 is attached to the attachment object B, when the inner cable 2 is pulled by an operation of the operation unit or the like, the insertion path 31 of the outer casing 3 is shortened so that the inner cable 2 has a shorter routing route. Try to be in a straight line. In this case, as shown in FIG. 2, the outer casing 3 may swing from a position indicated by a solid line to a position indicated by a two-dot chain line, for example. Since the movement of the outer casing 3 is repeated every time the inner cable 2 is operated, the outer casing 3 may be gradually detached in the axial direction only by the holding portion 42. However, in the present embodiment, one end 32 of the outer casing 3 is inserted into the insertion portion Is, and even if the outer casing 3 is shaken, the inner wall of the insertion portion Is and the outer periphery of the outer casing 3 come into contact with each other. The one end 32 of the casing 3 does not rattle. Therefore, it is possible to prevent the outer casing 3 from loosening in the direction in which the outer casing 3 comes off due to the shake of the outer casing 3 and the shakiness of the one end 32 due to the shake. Further, when the one end 32 of the outer casing 3 is press-fitted into the insertion portion Is, the axial movement of the outer casing 3 is suppressed by press-fitting at the insertion portion Is and gripping by the elastic force at the holding portion 42. Can do. Therefore, the outer casing 3 is unlikely to come off from the terminal member 4. And since the outer casing 3 is hard to come off from the terminal member 4, when the outer casing 3 is attached to the terminal member 4, additional processing such as caulking is unnecessary, and the inner surface of the holding portion 42 is provided with unevenness or is not removed. There is no need to provide additional members for stopping, and the installation work and structure are simplified. In particular, when the terminal member 4 is attached to the outer casing 3 by the caulking process, there is a possibility that the inner diameter of the outer casing 3 may change, and as a result, the inner cable 2 may be prevented from sliding. On the other hand, in the case of the control cable 1 according to the present embodiment, although it depends on the elastic force of the holding portion 42 and the amount of press-fitting into the insertion portion Is, it is easier to suppress the inner diameter change of the outer casing 3 than in the case of the caulking process. Therefore, there is little possibility of inhibiting the sliding of the inner cable 2.

In addition, in the said embodiment, although the attachment to the holding | maintenance part 42 of the outer casing 3 is performed before the terminal member 4 is attached to the attachment object B, after the terminal member 4 is attached to the attachment object B, The outer casing 3 may be attached to the holding part 42. Further, when the outer casing 3 is pushed in the axial direction after the terminal member 4 is attached to the attachment target B, the attachment portion 41 is engaged with the attachment target B, for example, the

end portions

41a and 41b of the attachment portion 41. Thus, the mounting portion 41 is stable without moving in the axial direction. Therefore, the outer casing 3 can be easily pushed into the insertion portion Is. Therefore, according to the control cable 1 of the present embodiment, for example, the outer casing 3 can be inserted into the insertion portion Is after the terminal member 4 is attached to the attachment object B, and the outer casing 3 is loosened from the insertion portion Is. Can be inserted without removing the attachment portion 41 from the attachment object B.

The use of the control cable 1 of the present embodiment is not particularly limited. For example, the control cable 1 is a low-load control cable having a low load applied during operation, such as a lightweight lid opening / closing operation or a lightweight passage switching member. Preferably used. For example, a thin control cable with an outer diameter of the outer casing of about 2 mm corresponds to a low-load control cable, and the operating load is applied to the outer casing when the operation target is operated by the operation unit. However, the load on the outer casing is small in the opening and closing operation of the lightweight lid and the operation of the lightweight passage switching member. Therefore, since the fitting strength between the outer casing and the terminal member does not have to be high, the terminal member can be easily molded with a normal hard plastic. In addition, when the outer diameter of the outer casing is as small as about 2 mm, it is difficult to fix the terminal member by caulking. Therefore, when attaching the terminal member, the control cable of the present invention is used for low loads. It can be suitably used for a thin control cable.

Second Embodiment
Next, a second embodiment of the control cable will be described. The features described in the first embodiment can be applied to the control cable of the second embodiment, and the features described in the second embodiment are applied to the control cable of the first embodiment. It is possible. Hereinafter, description of points common to the control cable of the first embodiment will be omitted, and the second embodiment will be described focusing on differences from the first embodiment.

As shown in FIGS. 5 to 7B, the control cable 1 of the present embodiment has a circumscribed member 5 that comes into contact from the outside of the holding portion. The circumscribed member 5 suppresses the one end 32 side of the outer casing 3 from being detached from the holding portion 42 when the holding portion 42 is deformed. The circumscribed member 5 can have a function that does not cause deformation of the holding portion 42 such that the one end 32 side of the outer casing 3 comes out of the holding portion 42. Such deformation of the holding portion 42 includes not only the case where the holding portion 42 is temporarily elastically deformed but also the plastic deformation of the holding portion 42. The deformation of the holding portion 42 suppressed by the circumscribed member 4 is inserted into the holding portion 42 such as a deformation in which the inner diameter of the holding portion 42 is expanded or a deformation in which the width of the slit S of the holding portion 42 is widened. The deformation | transformation of at least one part of the holding | maintenance part 42 and the change in a dimension which the one end 32 side of the outer casing 3 becomes easy to detach | leave are included.

The circumscribed member 5 is attached to the holding portion 42 so as to be able to contact the holding portion 42 from the outside (see FIG. 6), thereby suppressing the deformation of the holding portion 42 described above. When the circumscribed member 5 suppresses the deformation of the holding portion 42, the one end 32 side of the outer casing 3 inserted into the holding portion 42 is suppressed from being detached from the holding portion 42. Therefore, when an external force is applied to the control cable 1 (outer casing 3), such as when the control cable 1 is transported, assembled, or used, the one end 32 side of the outer casing 3 is inserted into the holding portion 42. Can be maintained.

In the present embodiment, the circumscribed member 5 is formed in a substantially cylindrical shape as shown in FIGS. 7 (A) and (B). More specifically, the circumscribed member 5 is formed in a substantially cylindrical shape having a circumscribed member side first opening 51 and a circumscribed member side second opening 52 at one end and the other end, and the inner surface 53 of the circumscribed member 5 is held. It is comprised so that the outer peripheral surface 42d of the part 42 may be contacted.

In the present embodiment, as shown in FIG. 7A, the inner surface 53 of the circumscribed member 5 is formed so as to increase in diameter toward the circumscribed member-side first opening 51. In this case, the outer member 5 is moved in the axial direction with respect to the holding portion 42 so that the holding portion 42 can be easily inserted into the outer member 5 from the first opening 51 on the outer member side. Attachment to 42 becomes easy. A method of attaching the circumscribed member 5 to the holding portion 42 is not particularly limited, but in the present embodiment, the circumscribed member 5 is fitted to the outside of the holding portion 42 by moving the circumscribed member 5 in the axial direction with respect to the holding portion 42. .

Further, the circumscribed member 5 may be configured to press the holding portion 42 in the direction of the central axis of the outer casing 3, for example. In the present embodiment, the inner diameter of the circumscribed member 5 is smaller than the outer diameter of the holding portion 42 before the circumscribed member 5 is attached. Here, the inner diameter of the circumscribed member 5 and the outer diameter of the holding portion 42 protrude when there is a portion protruding from the inner surface 53 of the circumscribed member 5 or the outer peripheral surface of the holding portion 42 (for example, a convex portion 53a described later). This refers to the inner and outer diameters including the part to be used. Since the circumscribed member 5 is configured to press the holding portion 42 in the central axis direction of the outer casing 3, when the circumscribed member 5 is attached to the holding portion 42, the circumscribed member 5 presses the holding portion 42 from the outside. . In the present embodiment, as shown in FIGS. 5 and 6, the slits S are formed in the holding portion 42, and the holding portion 42 is pressed so that the interval in the circumferential direction of the slit S is narrowed.

In this embodiment, it is comprised so that the outer peripheral surface of the holding | maintenance part 42 may be pressed by the some convex part 53a. As a modification of the present embodiment, for example, one convex portion 53 a having a width smaller than the width of the slit S of the holding portion 42 may be provided on the inner surface 53 of the circumscribed member 5. In this case, when the circumscribed member 5 is moved to the outside of the holding portion 42 in the axial direction, the convex portion 53a of the circumscribed member 5 is guided along the slit S of the holding portion 42, and the shaft of the circumscribed member 5 with respect to the holding portion 42 is The movement of the direction becomes easy. Note that the convex portion 53a described above is not necessarily provided, and the inner surface 53 may have a circular cross section perpendicular to the axial direction. Further, the length of the convex portion 53a in the axial direction is not particularly limited.

Next, the assembly of the control cable 1 of the present embodiment to the attachment target B will be described. In addition, since the control cable of this embodiment can be made into the assembly method similar to 1st Embodiment fundamentally, it is partially abbreviate | omitting about the common part.

As shown in FIG. 5, the one end 32 side of the outer casing 3 is attached to the holding portion 42. In the present embodiment, one or more protrusions (not shown) are provided along the circumferential direction on the inner peripheral surface of the holding portion 42, and the axial movement of the outer casing 3 with respect to the holding portion 42 is performed. Suppressed. After the one end 32 side of the outer casing 3 is attached to the holding portion 42, the circumscribed member 5 inserted into the outer peripheral side of the outer casing 3 is moved along the axial direction of the outer casing 3 from the state shown in FIG. The circumscribed member 5 is moved to the state shown in FIG.

As shown in FIG. 6, when the outer member 5 is attached to the outside of the holding portion 42, the inner surface 53 of the outer member 5 comes into contact with the outer peripheral surface 42 d of the holding portion 42, and the outer casing 3 is detached. The deformation of the portion 42 is suppressed. Therefore, the detachment of the outer casing 3 is suppressed. In this embodiment, since the circumscribed member 5 presses the holding portion 42 in the central axis direction of the outer casing 3, the holding force of the outer casing 3 of the holding portion 42 is increased and the holding portion 42 is expanded outward. Suppress. Thereby, the detachment | leave from the holding | maintenance part 42 of the outer casing 3 can be suppressed more.

Thereafter, as in the first embodiment, the attachment portion 41 is attached to the cutout portion N of the attachment object B (see FIGS. 1 and 2), and the cable end 21 of the inner cable 2 is attached to the operation portion or the operated portion not shown. Thus, the attachment of the control cable 1 to the attachment object B is completed. In the present embodiment, in addition to the effects described in the first embodiment, the detachment of the outer casing can be further suppressed as described above.

In the above-described embodiment, the circumscribed member 5 is configured in a substantially cylindrical shape, but the shape and structure of the circumscribed member 5 are from the outside of the holding portion 42 so as to prevent the holding portion 42 from being deformed. There is no particular limitation as long as the circumscribed member 5 can contact the outer peripheral surface 42d of the holding portion 42. The circumscribed member 5 may be, for example, a sandwiching structure that sandwiches the outer peripheral surface 42d of the holding portion 42, or a semicylindrical body that can be attached to the outside of the holding portion 42 and is divided along the axial direction. It is good also as a shape which has a split cylindrical part, and it is good also as a shape by which the slit was formed in the substantially cylindrical body in the axial direction. The circumscribed member 5 may be configured to be attached to the holding portion 42 as a separate member from the terminal member 4 as in the above-described embodiment. For example, the circumscribed member 5 extends from the end 41 a of the attaching portion 41 along the holding portion 42. It may be formed integrally with the terminal member 4. The material of the circumscribed member 5 can be, for example, synthetic resin, metal, rubber, or the like, but is not particularly limited as long as the above-described deformation of the holding portion 42 can be suppressed.

Further, when the circumscribed member 5 is configured to be pressed from the outside of the holding portion 42, at least one of the holding portions 42 is contracted or deformed in addition to making the inner diameter of the circumscribed member 5 smaller than the outer diameter of the holding portion 42. A circumscribed member configured to cover the portion and suppress the deformation of the holding portion 42 may be used. For example, a heat shrinkable tube or the like may be used as the circumscribed member 5. When a heat-shrinkable tube is used as the circumscribed member 5, a heat-shrinkable tube having an inner diameter before shrinkage larger than the outer diameter of the holding portion 42 is prepared, and the heat shrinkage is performed outside the holding portion 42 into which the one end 32 of the outer casing is inserted. Place the tube. It is also possible to bring the heat shrinkable tube into contact with the holding part 42 by contracting the heat shrinkable tube disposed outside the holding part 42 by applying predetermined heat.
