A wiring member fixing structure 1 is for fixing a wiring member 20 in a vehicle. A wiring member fixing structure 1 includes a planar member 10 , a wiring member 20 , and a fixing member 40 .

<Planar member>
The planar member 10 is a member provided in a vehicle. The planar member 10 is, for example, a member provided on the floor, ceiling, side surface (door), or the like of a vehicle. The planar member 10 is a member provided for purposes such as soundproofing and cushioning. The planar member 10 is, for example, a softly formed member. In the following description, it is assumed that the planar member 10 is a silencer, particularly a floor silencer disposed between a floor mat and a body of a vehicle. Specifically, the planar member 10 includes a body portion 12 .

The body portion 12 has one principal surface 13 and the other principal surface 14 . A wiring member 20 is arranged on one main surface 13 . A concave portion 16 in which the accommodating portion 44 is accommodated is formed in advance on the one main surface 13 .

The recessed portion 16 is formed in a portion of the body portion 12 . Recess 16 is formed such that a portion of one main surface 13 is recessed. In the example shown in FIG. 2, a through hole is formed as the concave portion 16 . That is, the recess 16 is formed so that the other main surface 14 is also recessed on the side opposite to the one main surface 13 . Of course, as the recess 16, a bottomed hole in which only one main surface 13 is recessed may be formed. When the concave portion 16 is a through hole, formation is facilitated. When the concave portion 16 is a hole with a bottom, it is possible to suppress deterioration of soundproofing.

A body portion 12 of the planar member 10 is formed in a plate shape from a soundproof material. Here, the body portion 12 of the planar member 10 is formed by applying an adhesive (binder) to resin foam chips such as foamed polyurethane and mixing them together, and compressing them in a steam atmosphere to integrally fix them. will be described as being formed by As such an adhesive, a well-known adhesive suitable for the material of the chip, such as an adhesive for urethane chips, can be used. The concave portion 16 is formed by, for example, a press during or after molding the body portion 12 .

However, the manufacturing method of the main body portion 12 of the planar member 10 is not limited to the one described above. For example, the body portion 12 of the planar member 10 may be formed by molding while foaming a resin material such as polyurethane, or may be formed using a non-woven fabric as a material. Further, for example, the body portion 12 of the planar member 10 may be formed by compressing countless fibrous members. In this case, the myriad fibrous members may be entangled and bonded, or may be fixed by an adhesive or the like. Such fibrous members may be natural fibers or chemical fibers.

In the example shown in FIG. 2, the portion of the body portion 12 of the planar member 10 where the concave portion 16 is not formed is formed flat, but it may be formed along the shape of the body or partially raised. It may have a portion exhibiting unevenness in the thickness direction for the purpose of.

<Wiring member>
The wiring member 20 is a member that is connected to a component mounted on the vehicle and transmits electricity or light to and/or from the component. The wiring member 20 is arranged on one main surface 13 of the planar member 10 . The wiring member 20 includes a flat wiring body. In the following description, it is assumed that the flat wiring body is the wiring body with sheet material 22 . The wiring body with sheet material 22 includes a plurality of linear transmission members 24 and a sheet material 30 .

The linear transmission member 24 may be any linear member that transmits electricity or light. For example, the linear transmission member 24 may be a general electric wire having a core wire and a coating around the core wire, or may be a bare conductor wire, a shielded wire, an enameled wire, a nichrome wire, an optical fiber, or the like. Various signal lines and various power lines may be used as the linear transmission member 24 for transmitting electricity.

Here, the linear transmission member 24 has a transmission line body that transmits electricity or light, and an outer skin that covers the transmission line body. In the following description, it is assumed that the linear transmission member 24 is a general electric wire 24 (hereinafter simply referred to as the electric wire 24). In other words, the electric wire 24 has a core wire 26 as a transmission line body and an insulating coating 28 as an outer sheath covering the transmission line body.

The core wire 26 is composed of one or more strands. The strands are made of conductors such as copper, copper alloys, aluminum, and aluminum alloys. When the core wire 26 is composed of a plurality of strands, the strands are preferably twisted. The insulating coating 28 is formed by extrusion molding a resin material such as PVC (polyvinyl chloride) or PE (polyethylene) around the core wire 26 . Here, the wire 24 is a so-called round wire having a circular cross section.

A plurality of electric wires 24 are arranged on the main surface of the sheet material 30 . The route of the electric wire 24 on the sheet material 30 may be appropriately set. In the example shown in FIG. 1, the electric wire 24 is arranged linearly on the sheet material 30, but it may be arranged in a curved manner, or may have both a straight portion and a curved portion. may be placed in Further, in the example shown in FIG. 1, the plurality of electric wires 24 are arranged side by side on the sheet material 30, but at least some of the plurality of electric wires 24 may extend along different paths.

A connector, for example, is provided at the end of the electric wire 24 , and the connector is connected to a mating connector provided on a component or the like to which the wiring member 20 is connected. Such a connector is formed, for example, by housing the ends of the wires 24 in the wire housing portion of the housing. In the example shown in FIG. 1 , the ends of the electric wires 24 extend outside the sheet material 30 , but the ends of the electric wires 24 may be positioned on the sheet material 30 . In this case, the housing may or may not be fixed directly to the sheet material 30 . Also, the ends of the electric wires 24 may be positioned on the planar member 10 or may extend outward from the planar member 10 .

The sheet material 30 keeps the plurality of wires 24 flat. Here, the electric wire 24 is arranged on the sheet material 30 . The electric wire 24 and the sheet material 30 are fixed. Such a fixation mode may be contact site fixation, non-contact site fixation, or a combination of both. Here, the fixed contact portion means that the contact portion between the electric wire 24 and the sheet material 30 is fixed by sticking. Non-contact part fixation is a fixation mode other than contact part fixation. 30 is sandwiched to maintain that state. In the following description, it is assumed that the electric wire 24 and the sheet member 30 are in a state of being fixed at the contact portion.

Such contact site fixation may be indirect fixation at the contact site, direct fixation at the contact site, or both may be used in different regions. Here, the indirect fixation of the contact portion means that the electric wire 24 and the sheet material 30 are indirectly adhered and fixed via an adhesive agent, an adhesive agent, a double-sided adhesive tape, or the like provided therebetween. Further, the direct fixation of the contact portion means that the electric wire 24 and the sheet material 30 are directly attached and fixed without interposing an adhesive or the like separately provided. In the direct fixation of the contact portion, it is conceivable that, for example, resin contained in at least one of the electric wire 24 and the sheet material 30 is melted to stick and fix. In the following description, it is assumed that the electric wire 24 and the sheet material 30 are in a state of directly fixing the contact portion.

In forming such a state in which the contact portion is directly fixed, the resin may be melted, for example, by heat or melted by a solvent. That is, the state of direct fixation of the contact portion may be the state of direct fixation of the contact portion by heat or the state of direct fixation of the contact portion by solvent. Preferably, the contact portion is directly fixed by heat.

At this time, the means for forming the state of direct fixation of the contact portions is not particularly limited, and known means such as welding, fusing, and welding can be used. For example, when the contact portion is directly fixed by heat by welding, various welding means such as ultrasonic welding, heat-pressure welding, hot-air welding, and high-frequency welding can be employed. Further, when the contact portion directly fixed state is formed by these means, the electric wire 24 and the sheet member 30 are brought into the contact portion directly fixed state by the means. Specifically, for example, when the contact portion directly fixed state is formed by ultrasonic welding, the electric wire 24 and the sheet material 30 are brought into the contact portion directly fixed state by ultrasonic welding.

In the case of directly fixing the contact portion, either one of the resin contained in the coating of the electric wire 24 and the resin contained in the sheet material 30 may be melted, or both of them may be melted. In the former case, the melted resin may stick to the outer surface of the unmelted resin, forming a relatively sharp interface. In the latter case, both resins may intermingle without forming a sharp interface. In particular, when the coating of the electric wire 24 and the sheet material 30 contain a resin that is easily compatible, such as the same resin material, both resins may be mixed and a clear interface may not be formed.

A material forming the sheet material 30 is not particularly limited. The material forming the sheet material 30 may contain resin such as PVC, PE, PET (polyethylene terephthalate), PP (polypropylene), or may contain metal such as aluminum or copper. good too. However, when the electric wire 24 and the sheet material 30 are formed in a state in which the contact portion is directly fixed, the insulating coating 28 of the electric wire 24 and the sheet material 30 are formed of a resin material that is easily compatible, such as the same resin material. is preferred.

The sheet material 30 may have fibers such as woven fabric, knitted fabric, or non-woven fabric, or may be formed by bonding without having fibers by extrusion molding, injection molding, or the like. . In the latter case, the sheet material 30 may be a foamed body, or may be formed to have a solid cross section without being foamed.

Moreover, the sheet material 30 may have a single-layer structure, or may have a multi-layer structure. When the sheet material 30 has a multi-layer structure, for example, resin layers may be laminated. Further, for example, it is conceivable that a resin layer and a metal layer are laminated. Further, for example, it is conceivable that a metal layer and a metal layer are laminated. When the sheet material 30 is configured by laminating a resin layer and a resin layer, layers having fibers may be laminated or layers having no fibers may be laminated, or a layer having fibers and a layer having fibers may be laminated. may be overlaid with a layer that does not have

When the sheet material 30 has a multi-layer structure, the sheet material 30 may be formed by laminating separately formed sheet-like members, or the sheet material 30 may be formed by one extrusion molding, injection molding, or the like. It may be molded.

<Fixing member>
The fixing member 40 is a member that fixes the wiring member 20 to the planar member 10 .

The fixing member 40 further includes an accommodation portion retaining piece 54 . The fixing member 40 further includes a projection extension part retaining piece 64 .

Here, the fixing member 40 is divided into a first member 42 and a second member 60. As shown in FIG. The first member 42 has an accommodating portion 44 , a locking projection 50 and a locked portion 56 . The first member 42 further has an accommodating portion retaining piece 54 . The second member 60 has a prong extension 62 and a locking portion 66 . The second member 60 further has a protruding portion retainer 64 . The first member 42 and the second member 60 are locked by the locking portion 66 being locked to the locked portion 56 .

The accommodating portion 44 is inserted into the planar member 10 . Here, the accommodation portion 44 is accommodated in the recess 16 . The accommodation portion 44 has an insertion opening 45 into which the protruding extension portion 62 is inserted. Here, the accommodating portion 44 has a plurality of split pieces 46 arranged in the circumferential direction so as to have a tubular shape as a whole, and a connecting tubular portion 47 that connects the plurality of split pieces 46 in the circumferential direction.

Here, eight split pieces 46 are arranged in the circumferential direction. Each split piece 46 is connected by a connecting tube portion 47 at one end thereof. Each split piece 46 has a thin portion at one end. The thin portion functions as a hinge portion. That is, when the projecting extension portion 62 is inserted into the accommodating portion 44, mainly the thin portion is elastically deformed, and the other end side is bent from this. Each split piece 46 is formed in the same shape. Of course, it is also possible that some split pieces 46 are formed in different shapes from each other.

Adjacent split pieces 46 are arranged in a line in the circumferential direction at intervals. In the example shown in FIG. 3 , the interval between the adjacent split pieces 46 is set to be smaller than the circumferential dimension of the split pieces 46 around the connecting portion with the connecting tube portion 47 . Of course, the interval between the adjacent split pieces 46 may be equal to or larger than the circumferential dimension of the split pieces 46 around the connecting portion with the connecting tube portion 47 . In other words, the interval between the adjacent split pieces 46 is not particularly limited and can be set as appropriate.

The connecting cylinder part 47 connects the plurality of split pieces 46 at one end side thereof. A portion of the accommodating portion 44 where the plurality of split pieces 46 are connected by the connecting tube portion 47 serves as an insertion opening 45 into which the projecting extension portion 62 is inserted. Below, in the accommodating part 44 and the split piece 46, the insertion port 45 side may be referred to as a base end portion, and the opposite side to the insertion port 45 side may be referred to as a distal end portion.

As shown in FIG. 4, the inner peripheral surface of the accommodating portion 44 is a tapered surface 48, which functions as a guide during insertion. More specifically, the accommodation portion 44 is formed so that the space becomes narrower as it goes deeper from the insertion port 45 before the protrusion extension portion 62 is accommodated. Here, the inner peripheral surface of each split piece 46 is formed so as to gradually approach from the proximal end toward the distal end. More specifically, here, the inner peripheral surface of each split piece 46 is formed so as to gradually come closer to the center from the proximal end toward the distal end. When the protrusion extension part 62 is inserted, the inner peripheral surface of each split piece 46 is gradually pushed by the protrusion extension part 62, so that the tip of each split piece 46 spreads outward gradually. bend.

The locking projection 50 is provided so as to extend outward from the accommodating portion 44 . The locking projection 50 is provided at the tip of the accommodation portion 44 . The locking projection 50 has divided locking projections 52 provided on the plurality of divided pieces 46 respectively. The split locking projection 52 is provided at the tip of the split piece 46 . Although the description here assumes that all of the split pieces 46 are provided with the split locking projections 52, this is not an essential configuration. Some split pieces may not be provided with split locking projections 52 .

The locking protrusion 50 is formed to fit in the recess 16 before being expanded by the protrusion extension 62 . Here, all the divided locking projections 52 are formed so as to be accommodated in the recesses 16 at the same time without being deformed before being expanded by the projection extension portions 62 .

The locking projection 50 is stuck inside the planar member 10 . The locking projection 50 is stuck into a portion of the interior of the planar member 10 where no hole is formed in advance. Here, each split locking projection 52 sticks into the planar member 10 from the inner peripheral surface of the concave portion 16 . In particular, each split locking projection 52 pierces a portion of the inner peripheral surface of the recess 16 where no hole is formed in advance.

The locking protrusion 50 is formed in a tapered shape that can be inserted into the planar member 10 . As a result, the locking projection 50 can pierce a portion of the interior of the planar member 10 where no hole is formed in advance. In particular, the locking projection 50 can pierce a portion of the inner peripheral surface of the recess 16 where no hole is formed. Here, the split locking projection 52 is formed in a tapered shape so as to be able to pierce the interior of the planar member 10 . As a result, the split locking projections 52 can pierce portions of the interior of the planar member 10 where no holes are formed in advance. In particular, the split locking projection 52 can pierce a portion of the inner peripheral surface of the recess 16 where no hole is formed. Specifically, as shown in FIGS. 2 and 3, only the thickness dimension of the split locking projection 52 is tapered out of the thickness dimension and the circumferential dimension. Here, the circumferential dimension of the split locking projection 52 gradually increases from the proximal end to the distal end, but it does not have to be changed. Furthermore, in the split locking projection 52, only the circumferential dimension out of the thickness dimension and the circumferential dimension may be tapered, or both of them may be tapered.

In the example shown in FIG. 4 , the locking projection 50 is formed to extend in a direction orthogonal to the insertion direction of the projection extension 62 before being widened by the projection extension 62 . The locking projection 50 extends toward the insertion opening 45 as shown in FIG. This makes it difficult for the fixing member 40 to come off from the planar member 10 . Here, the split locking protrusion 52 extends from the tip of the split piece 46 toward the base end of the split piece 46 while making an acute angle with the direction in which the split piece 46 extends, By bending the split piece 46 by , the locking projection 50 operates as described above.

The accommodation portion retaining piece 54 is formed to extend outward from the accommodation portion 44 and is hooked on the one main surface 13 of the planar member 10 . Here, the retaining piece 54 is formed so as to extend outward from the base end of the receiving portion 44 . In particular, here, the peripheral portion of the connecting tubular portion 47 is extended outward as it is to serve as a retaining portion retaining piece 54 . Accordingly, the retaining piece 54 is formed in a flange shape. The retaining piece 54 is formed to be larger than the recess 16 and is hooked on the periphery of the recess 16 .

As shown in FIG. 4 , the retaining piece 54 is formed so as to extend in a direction perpendicular to the insertion direction of the projecting extension 62 before it is expanded by the projecting extension 62 . Therefore, the locking projection 50 and the accommodation portion retaining piece 54 are in parallel before being spread by the projection extension portion 62 . The accommodating portion retaining piece 54 functions as a retainer that prevents the first member 42 from detaching forward in the insertion direction from the planar member 10 . On the other hand, the locking projection 50 mainly functions as a detent that restrains the first member 42 from returning backward in the insertion direction with respect to the planar member 10 .

The protruding extension 62 is housed in the receiving portion 44 . The projection extension portion 62 spreads the locking projection 50 outward and locks it inside the planar member 10 . Here, the projection extension 62 widens the receiving portion 44 and thereby widens the locking projection 50 . More specifically, the projection extension portion 62 widens each split piece 46 , thereby widening the split locking projection 52 .

The projecting extension portion 62 is formed in, for example, a columnar shape or a cylindrical shape. In the example shown in FIG. 2, the projection extension 62 is formed cylindrical. Accordingly, although a through hole 62h is formed in the protruding extension portion 62, this is not an essential configuration. A peripheral edge portion of the distal end portion of the projecting extension portion 62 is formed into a tapered surface 63 and functions as a guide during insertion. More specifically, when a force is further applied after the distal end portion of the projecting extension portion 62 abuts against the inner peripheral surface of the housing portion 44, the projecting extension portion 62 expands the housing portion 44 and is guided inward. go.

The extended projecting portion retainer piece 64 is formed to extend outward from the extended projecting portion 62 and is hooked to the edge of the receiving portion 44 . Here, the projection extension portion retaining piece 64 is formed so as to extend outward from the base end portion of the projection extension portion 62 . The protruding extended portion retaining piece 64 is formed in a brim shape. The protrusion extension part retaining piece 64 is formed to extend in a direction orthogonal to the extending direction of the protrusion extension part 62 . The protruding extended portion retaining piece 64 is formed larger than the insertion opening 45 and is hooked on the connecting tube portion 47 that is the peripheral portion of the insertion opening 45 . In particular, here, the protruding portion retaining piece 64 is formed to be larger than the concave portion 16 and is hooked to the receiving portion retaining portion 54 .

The first member 42 and the second member 60 are locked by locking the locked portion 56 and the locking portion 66 . The locked portion 56 is provided on the inner peripheral surface of the housing portion 44 . The locking portion 66 is provided on the outer peripheral surface of the projecting extension portion 62 . Locking protrusions are formed as both the locked portion 56 and the locking portion 66 . The locked portion 56 and the locking portion 66 function as a detent that prevents the second member 60 from returning backward in the insertion direction with respect to the first member 42 . The protruding extended portion retaining piece 64 functions as a retainer that prevents the second member 60 from coming off forward in the insertion direction with respect to the first member 42 .

In the state where the locked portion 56 and the locking portion 66 are locked, the portion of the first member 42 from the accommodating portion removal preventing piece 54 to the locked portion 56 is aligned with the extended projecting portion removal preventing piece 64 of the second member 60 . to the locking portion 66. This makes it difficult for the first member 42 and the second member 60 to rattle when locked. In addition, if the first member 42 and the second member 60 rattle in the locked state, inserting another member such as the sheet material 30 between the accommodation portion retaining piece 54 and the projecting extended portion retaining piece 64 Rattle can be suppressed.

As shown in FIG. 2 , the distal end portion of the fixing member 40 is housed inside the planar member 10 while the fixing member 40 is engaged with the planar member 10 . In other words, the tip portion of the fixing member 40 does not protrude outward from the other main surface 14 .

Furthermore, here, as shown in FIG. 4 , the tip of the first member 42 is housed inside the planar member 10 before the fixing member 40 is engaged with the planar member 10 . That is, the tip portion of the first member 42 does not protrude outward from the other main surface 14 . The height dimension of the first member 42 from the accommodation portion retaining piece 54 is smaller than the thickness dimension of the planar member 10 at the portion where the recess 16 is formed.

It is conceivable that the first member 42 and the second member 60 are integrally molded products made of metal, resin, or the like, for example, by injection molding using a mold. When the first member 42 is molded from a resin material, and when the locking protrusion 50 pierces a portion of the planar member 10 in which no holes are formed in advance, the locking protrusion 50 is pushed from the planar member 10 . is preferably hard.

<Fixation of wiring member to planar member>

A through hole 35 is formed in the fixed piece 34 . The fixing piece 34 is sandwiched between the accommodation portion retaining piece 54 and the planar member 10 in such a manner that the accommodation portion 44 is inserted into the through hole 35 .

In the example shown in FIG. 1, the fixing pieces 34 are provided at the four corners of the rectangular sheet material 30, but this is not an essential configuration. The position at which the fixing piece 34 is provided may be appropriately set. Further, the sheet material forming the fixed piece 34 may be provided separately from the sheet material 30 forming the wire installation portion 32, and the two may be fixed. Alternatively, the receiving portion 44 may be inserted between the wires 24 in the wire arrangement portion 32 without providing the fixing piece 34 . Further, the through hole 35 through which the accommodating portion 44 is passed may not be formed in advance.

Further, in the wiring body 22 with the sheet material in which the sheet material 30 covers only one side of the electric wires 24, the sheet material 30 of the sheet material 30 and the electric wires 24 is disposed on the planar member 10 side, but this is essential. is not the composition of Of the sheet material 30 and the electric wires 24, the electric wires 24 may be arranged on the planar member 10 side.

For example, it is conceivable that the adhesive tape is spirally wound around the plurality of linear transmission members 24 in a manner such as loose winding or double winding to bundle the plurality of linear transmission members 24 . Further, for example, it is conceivable that a plurality of linear transmission members 24 are bundled by winding the protective sheet material in a sushi-rolled shape or a palm-to-face shape. Further, for example, it is conceivable that a plurality of linear transmission members 24 are accommodated and bundled in a tubular member such as a corrugated tube. Further, for example, it is conceivable that a plurality of linear transmission members 24 are bundled by wrapping an adhesive tape, a binding band, or the like around the linear transmission members 24 at a plurality of locations spaced apart along the longitudinal direction. .

If the cover is separate from the sheet material 30, it may be of the same kind as the sheet material 30, or may be of a material, structure, function, etc. different from the sheet material 30.

So far, the description has been made on the assumption that the planar member 10 does not have a hole in which the locking projection 50 is inserted, but this is not an essential configuration. Holes into which the locking projections 50 are inserted may be formed in the planar member 10 in advance. In this case, the tip of the locking projection 50 may not be tapered.

Although the explanation has been made so far assuming that the accommodating portion 44 is divided, this is not an essential configuration. The housing portion 44 may not be divided. Further, even when the accommodating portion 44 is divided, it does not have to be divided into eight. It may be divided into 2 to 7, or may be divided into 9 or more.

Moreover, a part of the structure of the fixing member 40 may be omitted. For example, the retaining piece 54 may be omitted. In this case, it is preferable that the first member 42 is prevented from coming off and detached from the planar member 10 by engaging the locking protrusion 50 with the planar member 10 . Further, for example, the protrusion extension part retaining piece 64 may be omitted. In this case, it is preferable that the second member 60 is prevented from coming off and from returning to the first member 42 by engaging the locked portion 56 and the locking portion 66 .

The positions, shapes, and the like of the locked portion 56 and the locking portion 66 are not limited to those described above. Regarding the positions of the locking portion 66 and the locked portion 56 , for example, the locked portion 56 may be provided on the receiving portion retaining piece 54 and the locking portion 66 may be provided on the projecting extended portion retaining piece 64 . Further, for example, the locked portion 56 may be provided at the distal end of the housing portion 44 and the locking portion 66 may be provided at the distal end of the projecting extension portion 62 . Regarding the shapes of the locked portion 56 and the locking portion 66, for example, one of them may be a locking concave portion. Specifically, for example, a through hole 35 may be formed as the locked portion 56 in the inner peripheral surface of the accommodating portion 44 , and the locking portion 66 may be formed to lock into the through hole 35 .

So far, the fixing member 40 has been described as being divided into the first member 42 having the receiving portion 44 and the locking protrusion 50, and the second member 60 having the protrusion extension portion 62, but this is essential. is not the composition of The housing portion 44, the locking protrusion 50, and the protrusion extension portion 62 may be integrally molded to form a fixing member. As such an integral fixing member, for example, a rod-shaped projecting extension 62 passed through the interior of the housing 44 is connected to one end of the cylindrical housing 44, and the projection extending 62 is pulled. It is conceivable that the intermediate portion of the receiving portion 44 is buckled and widened outward to serve as a locking projection 50 .

Further, even when the fixing member 40 is divided into the first member 42 and the second member 60, the configuration is not limited to that described above. For example, it is conceivable that the first member 42 and the second member 60 are connected so as not to separate. Further, for example, it is conceivable that the second member 60 is formed so as to be inserted into the first member 42 from the locking projection 50 side.

When the first member 42 and the second member 60 are connected so as not to separate, the first member 42 and the second member 60 are connected by, for example, a hinge or a flexible elongate strip. It is conceivable that It is conceivable that such a hinge or band-shaped piece is provided, for example, so as to connect the edge of the accommodation portion retaining piece 54 of the first member 42 and the edge of the projecting extended portion retaining piece 64 of the second member 60 . be done.
