Description

TECHNICAL FIELD The present invention relates to an installation object installation device for installing an installation object such as a box into the opening of the groove of an installation object installation member having a groove formed in the longitudinal direction via a gripping base, and to a gripping base. .

For example, in Patent Document 1, in order to attach a box to a wiring pole, each engagement groove formed at both ends in the width direction of a wiring recess formed continuously in the longitudinal direction of the wiring pole is disclosed. By locking the curved plate-shaped box mounting member and holding the box mounting member so that it does not fall under its own weight, screw the box mounting member and the bottom plate of the box together with screws. A structure is known in which a box is fixed to a wiring pole by pulling the box mounting member toward the front.

However, in the above-described box mounting structure, the box cannot be mounted unless the box mounting member is held by the operator's hand to prevent it from falling under its own weight, which makes mounting the box troublesome. In addition, in order to place the box mounting member at a predetermined position (box mounting position) with respect to the wiring box, fit the box mounting member into the wiring recess from one end of the wiring pole in the axial direction, and then move it to the predetermined position. It was necessary to slide the box mounting member, and arranging the box mounting member relative to the wiring pole was also troublesome.

On the other hand, as disclosed in Patent Document 2, the support body 1 has elastic leg portions 6 formed below the pair of engaging portions 2, and the width of each engaging portion 2 is determined by the support made of channel steel. It is narrower than the opening width of the member S, and the combined length of the pair of engaging parts 2 is longer than the opening width, and the pair of engaging parts 2 of the support body 1 is formed along the continuous opening direction of the supporting member S. At the same time, with the elastic legs 6 compressed and deformed by a predetermined amount, the support body 1 is rotated by 90 degrees so that each engagement portion of the support body 1 is connected to each lip portion L of the support member S. 2 are brought into elastic contact with each other, and the support body 1 is fixedly arranged with respect to the support member S without shifting from a predetermined position.

However, the operation of rotating the support 1 by 90 degrees while holding the elastic legs 6 of the support 1 pressed against the elastic restoring force is difficult to perform during the period from the start to the end of the rotation operation. In all cases, it was necessary to keep pressing the support 1, which was a difficult task requiring both dexterity and a large pressing force.

In this state, when the clamping base is rotated in a predetermined direction, a part of each clamping part formed at both ends of the clamping base in the longitudinal direction is moved to the back surface of each clamped end edge of the installation member. A part of each clamping part enters the fitting groove formed on the side, and due to the biasing force directed toward the front side of the biasing means, a part of each clamping part comes into elastic contact with the back surface of each clamped end edge. The clamping base is temporarily fixed to each clamped end edge of the installation member, and does not shift in the longitudinal direction of the groove. Then, when the clamping base is slightly rotated in the same direction, the entire clamping parts at both longitudinal ends of the clamping base are biased toward the front by the biasing force of the biasing means, and the installed body The clamping base is fitted into the fitting groove on the back side of each clamped end edge of the installation member, and the clamping base is fixedly attached to the target position of the installation member installation member without sliding in the longitudinal direction of the groove. Ru.

In the above state, the installation object is placed on the front side of each clamped end edge of the installation object installation member, and the installation object is attached to the clamping base attached to the installation object installation member through the pulling connection means.

In this way, according to the invention of claim 1, without sliding the holding base with respect to the groove formed in the longitudinal direction of the installation member installation member, the installation position of the installation body in the groove can be moved in the longitudinal direction of the holding base. The clamping base can be fixedly attached to a specific position of the installation member by simply rotating the clamping base after arranging it along the direction in which the groove is formed. To quickly and easily perform the work of installing an installation body on a body installation member. Moreover, the biasing force of the biasing means against the back surface of each clamped end edge of the installation member of the clamping part at both ends of the clamping base in the longitudinal direction rotates the clamping base, and the clamping parts at both ends of the clamping base rotate. The angle at which the holding base is rotated when the biasing force is applied is small, starting just before the installation member is completely fitted into the fitting groove of the installation member, so the rotation of the holding base relative to the installation member is Installation work is also easy.

In the invention of claim 2, in the invention of claim 1, the biasing means is constituted by elastically deformable biasing parts integrally provided at both ends of the clamping base in the longitudinal direction, and The portion is characterized in that it is elastically deformed by contacting a deformation-inducing contact portion provided on the back side of each of the pinched end edges.

According to the invention of claim 2, the biasing means includes biasing portions integrally provided at both ends of the clamping base in the longitudinal direction, and biasing portions are provided on the back side of each clamped end edge of the installation member installation member. When the biasing section comes into contact with the provided deformation-inducing contact section, deformation of the biasing section is induced. The operation for attaching the clamping base becomes easier than when the clamping base is provided.

It is characterized in that it makes elastic contact with the deformation-inducing contact portion.

According to the invention of claim 3, the biasing means is constituted by an elastic piece that is integrally provided on the back side of the holding base, and the elastic piece is arranged on the inside surface of the groove on the back side forming the fitting groove. When the elastic piece starts elastic deformation by partially contacting the deformation-inducing abutting portion, and the holding portion is placed at the normal position, the elastic piece is entirely elastic against the deformation-inducing abutting portion. The elastic piece has a configuration in which the elastic piece starts elastic deformation immediately before the clamping base is attached to the proper position of the installation member, so that the clamping member resists the biasing force of the elastic piece. Since the angle at which the base is rotated is small, the clamping base can be easily attached to the installation member.

The invention according to claim 4 is the invention according to claim 3, wherein the elastic piece is arranged on the back surface of the holding part and extends in the longitudinal direction at both ends of the base body in the longitudinal direction, It is characterized in that it is bent toward the front side of the holding portion, and when the bent portion contacts the deformation-inducing contact portion, it is elastically deformed toward the front side.

Therefore, when rotating the clamping base and inserting each clamping part at both ends into the fitting groove of the installation member installation member, the elastic piece and the inner surface of the groove on the back side of the fitting groove are connected. When the elastic piece is inserted into the fitting groove, the elastic piece smoothly deforms elastically without being caught. Therefore, the clamping base can be attached simply by casually rotating the clamping base within the groove of the installation member.

The invention according to claim 5 is the invention according to claim 3 or 4, in which the clamping base is in contact with the deformation inducing abutting portion to prevent the entire clamping base from moving to the back side of the groove. It is characterized in that the rear-side regulating part that regulates is arranged at a position that is spaced from the front side with respect to the elastic piece.

As in the invention of claim 7, when the installation member is a pole that is erected with the extending direction of the pair of end edges to be held in the upright direction, the holding base is attached to the pole. In this case, since the clamping base is pressed against the back surface of the clamped end edge by the biasing force of the biasing means, there is no risk of it falling due to its own weight. Therefore, the work of installing an installation object such as a box on the pole becomes easy.

According to the eighth aspect of the invention, a pair of pinched end edges extending linearly in one direction are arranged opposite to each other at a predetermined interval across a front opening of a groove formed toward the back side. In order to install the installation body on the front side of the front opening of the installation member, so as to cross the front opening, the installation body is pulled toward the front side by the pulling and connecting means, so that the installation member and the pair of A clamping base that clamps the clamped end edge of the

According to the present invention, without sliding the holding base with respect to the groove formed in the longitudinal direction of the installation member installation member, the longitudinal direction of the holding base is set at the installation position of the installation member in the groove in the direction in which the groove is formed. The clamping base can be attached in a fixed state to a specific position on the installation member installation member by simply rotating the clamping base after placing the installation object along the clamping base. Installation work can be done quickly and easily. Moreover, the biasing force of the biasing means against the back surface of each clamped end edge of the installation member of the clamping part at both ends of the clamping base in the longitudinal direction rotates the clamping base, and the clamping parts at both ends of the clamping base rotate. This starts just before the installation member is completely fitted into the fitting groove of the installation member, and the angle at which the clamping base is rotated while the biasing force is applied is extremely small. The installation work is also easy.

Hereinafter, the present invention will be explained in more detail by citing the best embodiment. First, an example in which the present invention is applied to a wiring pole P will be described with reference to FIGS. 1 and 2. The wiring pole P is erected on the premises in order to draw in an overhead electric wire for supplying power to a house and connect the overhead electric wire to an underground electric wire via a box B. The wiring pole P includes an irregular cylindrical outer cylinder A in which a large concave wiring groove 31 is continuously formed in the axial direction in a part of the circumference, and a cross section slightly smaller than that of the outer cylinder A. It consists of an inner cylinder D which is formed into a small similar shape and which is inserted into the outer cylinder A and also has an irregular cylindrical shape. The inner cylinder D is inserted into the outer cylinder A by a predetermined length, and in the part where they overlap each other, the outer cylinder A and the inner cylinder D are arranged in the diametrical direction of each cylinder A, D. They are connected via two connecting bolts 41 and nuts 42. A clamping base V according to the present invention is attached to the front opening 32 of the wiring groove 31 in the outer cylinder A, and a box B is attached to the front opening 32 of the wiring groove 31 in the outer cylinder A through the clamping base V. is installed. The wiring groove 43 of the inner cylindrical body D is covered with a wiring cover 44, and a rubber cap 45 having a wire lead-in portion 45a is fitted to the upper end of the inner cylindrical body D. Directly below the cap 45 in , a band 47 is attached to which a tension wire 46 for stably supporting the wiring pole P is connected.

Next, with reference to FIG. 3, the outer cylinder A to which the holding base V is attached will be described. The outer cylindrical body A has an irregular cylindrical shape in which a wiring groove 31 having an isosceles trapezoidal cross section in a part of the circumferential direction enters the inner side of the outer cylindrical body A and is formed in a concave shape. At both widthwise ends of the front opening 32 of the wiring groove 31 of the outer cylinder A, a pair of protrusions 33 are formed to protrude outward in the radial direction of the outer cylinder A. At the tip of the protruding portion 33, a pair of band-shaped edge plate portions 34 to be held are parallel to the back flat plate portion 31a at the back bottom of the wiring groove 31, and are attached along the axial direction of the outer cylinder A. Holding portions 2, which will be described later, formed at both ends of the holding base V in the longitudinal direction are inserted into the rear side of each held edge plate portion 34 of the protruding portion 33 in a fitted state. A fitting groove 35 is formed, and the groove-forming inner surface on the back side of the fitting groove 35 is formed in an arc shape, and when the elastic piece 4 (described later) comes into contact with the holding base V, the elastic piece 4 is This serves as a deformation-inducing contact portion 36 that is elastically deformed. On the back side of the clamped edge plate part 34, there is a sharp contact part 37 which the clamping part 2 of the clamping base V comes into contact with by being pressed by the restoring force of the elastic piece 4 which is elastically deformed. It is formed to protrude into the groove 35. The bottom surface of the fitting groove 35 is an inclined bottom surface 35a extending substantially in the radial direction of the outer cylinder A.

The distance between the inner end surfaces 34a of the pair of edge plates 34 to be held, that is, the width W of the front opening 32 of the wiring groove 31 is determined by the longitudinal dimension L ₃ of the base body 1 of the holding base V [FIG. (b)] corresponds to (is equivalent to).

Next, with reference to FIGS. 4 to 6, it is placed in the front opening 32 of the wiring groove 31 of the outer cylindrical body A, attached to the pair of end edge plate parts 34 to be held, and The holding base V for installing the box B on the front surface of the wiring groove 31 of the cylinder A will be explained. The holding base V is molded by injection molding of resin, and has fitting grooves of the outer cylinder A at both longitudinal ends of the base body 1 in the shape of a thick rectangular plate, and in the center along the thickness direction. Each of the clamping parts 2 to be inserted and fitted into the base body 1 extends in the longitudinal direction, and on the front side of the base body 1, there is a connection between each end face of both longitudinal ends of the base body 1 and the front surface of each clamping part 2. A stepped portion 8 is formed in between, on which each clamped edge plate portion 34 of the outer cylinder A is arranged. Since the holding portion 2 extends in the longitudinal direction of the base body 1 while maintaining the width of the base body 1, its overall shape extends in the lateral direction of the base body 1 when viewed from the front. The clamping part 2 has a substantially rectangular shape extending in the longitudinal direction, and the clamping part 2 is attached to each of the fitting grooves by rotating a clamping base V inside the wiring groove 31 of the outer cylindrical body A. A rotation prevention part 3 is provided to protrude from one side of the base body 1 in the short direction to prevent the clamping base V from being rotated beyond the normal position when the base body 35 is inserted and fitted into the base body 1. ing. After the clamping base V is placed in the wiring groove 31 of the outer cylinder A, the clamping base V is rotated clockwise when viewed from the front, and the clamping parts 2 at both longitudinal ends of the base body 1 are rotated clockwise when viewed from the front. are inserted and fitted into each of the fitting grooves 35 of the outer cylindrical body A, so that the rotation prevention part 3 is placed in the rear side of the holding part 2 in the rotation direction, and in the lateral direction of the base body 1. It is placed prominently. Further, on the back surface of each clamping portion 2, both ends of the clamping base V in the longitudinal direction are connected to the inclined bottom surface 35a of the fitting groove 35 of the outer cylinder A over the entire length of the clamping base V in the short direction. It has an inclined end surface 2a that widens toward the front side so that it can be placed on the front side.

The longitudinal dimension _L1 of the clamping base V is longer than the width W of the front opening 32 of the wiring groove 31, and is the maximum dimension of the clamping base V in the lateral direction including the rotation prevention part 3. _L2 is shorter than the width W of the front opening 32, and the longitudinal direction of the holding base V is aligned with the direction in which the wiring groove 31 is formed or the direction in which the pair of end plate parts 34 to be held are extended. As a result, the dimensions are such that the holding base V can be placed in the front opening 32 of the wiring groove 31.

On the rear side of each clamping part 2 in the clamping base V, at the central part in the width direction, the clamping base V arranged in the wiring groove 31 of the outer cylinder A is rotated clockwise. Immediately before the clamping base V is placed at the final placement position, the outer cylinder body A starts contacting the curved deformation-inducing contact portion 36, thereby elastically deforming the clamping base V toward the front side. Elastic pieces 4 each having a possible curved shape are arranged. That is, each elastic piece 4 extends in a direction opposite to the deformation-inducing contact portion 36 of the outer cylinder A in a cross-sectional view with the holding base V attached to each fitting groove 35 of the outer cylinder A. It is bent (see FIG. 11) and is integrally formed along the longitudinal direction of the base main body 1 at both ends of the base main body 1 in the longitudinal direction and at the center in the short direction thereof. In addition, in a front view of the holding base V, a rectangular through hole 5 is formed in a portion of each holding part 2 where the elastic piece 4 is arranged on the back side. The through hole 5 is a hole of a slide mold (not shown) for molding the elastic piece 4 having a free end on the back side of the holding part 2. It has the function of a void that avoids interference with the holding part 2 when it is elastically deformed.

Each clamping part 2 of the clamping base V is inserted and fitted into each fitting groove 35 of the outer cylinder A on both sides of the elastic piece 4 in the transverse direction of the clamping base V, so that the clamping base V is properly fitted. When the clamping base V is pressed toward the axis of the outer cylindrical body A in a state where the clamping base V is placed in the position, a regulating step portion 6 is arranged to restrict the amount of retraction of the clamping base V, It is formed integrally with the base body 1 and the holding part 2, respectively. That is, the regulating step portion 6 is arranged at a position that is located in front of the holding base V with respect to the portion of the elastic piece 4 that abuts the deformation-inducing abutting portion 36 of the outer cylinder A. That is, the back surface 6a of the regulating step 6 (see FIGS. 4(b) and 6(b)) is placed in front of the holding base V by a predetermined dimension G with respect to the abutting portion of the elastic piece 4. There is.

Each corner of the portion of the base main body 1 that is disposed on the front side of each clamping part 2 is connected to a In order to facilitate the rotation by coming into contact with the inner end surface 34a of the clamped end edge plate part 34, and to maintain the state in which the clamping base V is disposed at the normal position of the outer cylinder A, the circular arc-shaped It is chamfered to form a free rotation prevention part 7. A plurality of circular first screw holes 11 are formed in the longitudinal center of the base body 1 at regular intervals in the lateral direction, and each first screw hole 11 is formed along the longitudinal direction. A plurality of elongated second screw holes 12 are formed on both sides. The first and second screw pilot holes 11 and 12 are opened only on the front side, and have a non-penetrating structure with a residual flesh part 13 with a small amount of flesh left on the back side (back side). ing. Incidentally, the recesses 14 formed between the respective free rotation prevention parts 7 at both ends of the base body 1 in the longitudinal direction are holes of a slide mold during molding, similar to the through holes 5.

Next, the order in which the holding base V is attached to the front opening 32 of the wiring groove 31 of the outer cylindrical body A of the wiring pole P will be described with reference to FIGS. 7 to 13. Note that the inner cylindrical body D is not shown in FIGS. 7 to 13. The longitudinal and lateral dimensions L ₁ and L ₂ of the holding base V with respect to the width W of the front opening 32 of the wiring groove 31 of the outer cylinder A are as described above, so as shown in FIG. In addition, when the longitudinal direction of the holding base V is set at a certain angle θ ₁ or more with respect to the horizontal line H, the holding base V can be placed inside the front opening 32 of the wiring groove 31. Note that in FIG. 7, θ ₁ is 50°. In this state, as shown in FIG. 8, when the holding base V is rotated clockwise and θ ₂ =30°, a portion of each holding part 2 at both longitudinal ends of the holding base V is rotated. are inserted into the respective fitting grooves 35 arranged opposite to the front opening 32 of the wiring groove 31 of the outer cylindrical body A, so that the holding base V is in a state where it cannot come out to the front side. The elastic piece 4 is on the verge of contacting each deformation-inducing contact portion 36 of the outer cylinder A, but is not in contact with it.

When the holding base V is further rotated and θ ₃ =20° as shown in FIG. When the contact starts and the deformation of each elastic piece 4 is induced, the rotational force required to rotate the holding base V from then on becomes larger compared to the moment before. Then, when the holding base V is further rotated so that its longitudinal direction is along the horizontal line H, as shown in FIG. 10 and FIG. As the prevention portions 3 approach the inclined bottom surfaces 35a of the fitting grooves 35 with a slight gap, further rotation of the clamping base V becomes impossible, and the clamping base V The portion 2 is inserted and fitted into each fitting groove 35 of the outer cylindrical body A and placed horizontally. In the attached state of the clamping base V, each elastic piece 4 contacts each deformation-inducing abutment part 36 of the outer cylinder A, and is elastically deformed toward the front side, so that each clamping part 2 of the clamping base V is that each elastic piece 4 is brought into elastic contact with each sharp abutment portion 37 formed on the back surface of each clamped end edge plate portion 34 of the outer cylinder A, and that each elastic piece 4 is in contact with the deformation-inducing abutment portion of the outer cylinder A. 36 is increased, the holding base V is able to reach the target position of the outer cylinder A without being slid downward under its own weight, that is, without falling under its own weight. The holding base V is stably attached to the holding base V.

In the above, the clamping base V is rotated clockwise to attach the clamping base V to the outer cylinder A when the box B is installed on the outer cylinder A of the wiring pole P. Clockwise rotation, which is the direction of rotation of the screw J when connecting the bottom plate portion 25 of the box B and the clamping base V by threading the screw J with respect to the clamping base V attached to the cylinder body A. This is to prevent the clamping base V attached to the outer cylinder A from being rotated in the opposite direction and loosening or coming off due to the clockwise rotation.

In this way, the direction in which the wiring groove 31 of the outer cylinder A is formed can be adjusted without sliding the holding base V with respect to each fitting groove 35 that is arranged opposite to the front opening 32 of the wiring groove 31 of the outer cylinder A. By rotating the clamping base V at a specific position along the wiring groove 31 of the outer cylinder A, the clamping base V can be attached to the specific position of the outer cylinder A. The holding base V can be easily attached to any position.

In addition, just before the clamping base V is rotated and each clamping part 2 at both ends in the longitudinal direction is fitted into each fitting groove 35 of the outer cylinder A, the inclined end surface of the clamping part 2 is 2a and the inclined bottom surface 35a of the fitting groove 35 are parallel to each other and can be brought into close contact with each other. By bringing the similarly outwardly expanding inclined end surface 2a of the holding portion 2 of the holding base V into close contact with or close to the outwardly expanding inclined bottom surface 35a, the holding base V is easily pushed forward, and this structure also This makes it easy to attach the clamping base V to each fitting groove 35 of the cylindrical body A.

In this way, each elastic piece 4 of the holding base V comes into contact with each deformation-inducing contact portion 36 of the outer cylinder A, so that the holding base V is moved against the restoring force (biasing force) of each elastic piece 4. The only thing that needs to be rotated is a slight angle just before the clamping base V is placed in its normal position. Here, "to rotate the holding base V against the restoring force (biasing force) of each elastic piece 4" means, more precisely, that the elastic piece is generated by the restoring force (biasing force) of each elastic piece 4. 4 and the deformation-inducing contact portion 36 to rotate the holding base V against the frictional force between the holding base V and the deformation-inducing contact portion 36. Therefore, the structure is such that the clamping base V is attached to the outer cylinder A by using the restoring force (biasing force) of each elastic piece 4, but the clamping base V is rotated with respect to the outer cylinder A. The operation of moving and attaching does not require a large rotational force or delicate operation, and it is only necessary to casually rotate the holding base V with respect to the outer cylinder A, so the operation is easy.

In addition, if it is found that the attachment height position is not appropriate after the clamping base V has been attached to the predetermined height position of the wiring groove 31 of the outer cylinder A, the restoring force of each elastic piece 4 may be When the holding base V is pushed toward the back side against the force and the holding base V is slightly separated from the sharp contact portion 37 on the front side, the friction between the elastic piece 4 and the deformation-inducing contact portion 36 is When the clamping base V is slid to the desired position against the force and the pressing is released, the clamping base V is slightly returned to the front side by the restoring force of each elastic piece 4 and slides at the desired position. It is attached without falling. In this way, the magnitude of the restoring force of the elastic piece 4 is such that the holding base V can be wired with human power against the frictional force between the elastic piece 4 and the deformation-inducing contact portion 36 generated by the restoring force. It is large enough to be slid along the groove 31. In other words, the restoring force of the elastic piece 4 is due to two factors: being able to hold the holding base V at the target position without sliding and falling, and being able to slide the holding base V along the wiring groove 31 against the frictional force. This size satisfies two conditions at the same time.

In addition, when the clamping base V is attached to the target position of the outer cylinder A so that it will not slip off due to its own weight, as shown in FIG. Each of the regulating step portions 6 arranged on both sides of the elastic piece 4 has a slight gap 21 with respect to each deformation-inducing contact portion 36 of the outer cylinder A, and is out of contact with each other. When the box B is attached to the clamping base V attached to the outer cylinder A using a plurality of screws J, the clamping base V is attached to the clamping base V against the restoring force of each elastic piece 4. When the pushing force F toward the rear side is applied, the back surface 6a of each regulating step 6 of the clamping base V comes into contact with the deformation-inducing abutting portion 36 of the outer cylinder A, as shown in FIG. By contacting the clamping base V, the movement of the clamping base V to the rear side beyond this is restricted, and when the pressing force against the clamping base V to the rear side is released, the restoring force of each elastic piece 4 causes the clamping base V to move further to the rear side. V is returned to its normal position at the front end. Thereby, the maximum amount of deformation of the elastic piece 4 is regulated, and the holding base V is stably attached to each fitting groove 35 of the outer cylinder A.

In the above, the attachment of the holding base V to the outer cylindrical body A that constitutes the wiring pole P was explained in principle, but in reality, the box B is installed on the outer cylindrical body A of the wiring pole P. As shown in FIGS. 14 and 15, two clamping bases V are placed at the installation position of the box B in the outer cylinder A with an interval corresponding to the height dimension of the box B. Attach it. After that, the bottom plate part 25 of the box B is brought into contact with the front surface of each clamped edge plate part 34 of the outer cylinder A, and the bottom plate part 25 and each clamping base V attached to the outer cylinder A are connected to each other. and are connected via screw J. The screw J is screwed into either the first or second screw holes 11 and 12 of the holding base V by screw rotation.

In a state where the bottom plate portion 25 of the box B and the two clamping bases V are connected via the screws J, each clamping base V and the bottom plate portion 25 of the box B are arranged to face each other at each clamped end edge. By holding the plate portion 34, the box B is attached to the target position of the wiring pole P. Since the holding base V attached to the outer cylindrical body A is attached without falling under its own weight, the installation work of the box B becomes easy. Furthermore, even if the clamping base V is pushed to the rear side when screwing the screw J, the clamping base V will not retreat beyond the dimension _L1 , and furthermore, after screwing the screw J, Due to the restoring force of each elastic piece 4, the holding base V returns to its normal position at the front end, so the box B can be securely installed on the outer cylindrical body A of the wiring pole P via the two holding bases V. . In addition, in FIG. 14, 48 indicates an electric wire arranged in the wiring groove 31 of the outer cylinder A.

In the present invention, it is essential that the clamping base V is biased toward the rear side of the clamped end edge plate portion 34 by a biasing means, and in the above embodiment, the clamping base V is It is composed of an elastic piece 4 that is integrally provided, and because it is integral, it is easy to attach it to the outer cylinder A, and there is no risk of losing the part that functions as the biasing means. However, the biasing means in the present invention may be a structure in which an elastic piece is provided on the back surface of the end plate portion 34 to be held, or a spring provided on the side of the holding base V or the outer cylindrical body A. .

The restriction stepped portion 6 of the above embodiment includes a “rear side restriction portion” specified in claim 5 for preventing the entire holding base V from moving beyond a certain level to the rear side of the wiring groove 31, and an elastic piece. Although the "regulating stepped portion" specified in claim 10 for regulating the maximum amount of deformation of item 4 is also used, it may be provided separately.
