Description

The present invention relates to a grommet and a control cable assembly including the grommet and a control cable.

For example, when it is necessary to route a control cable between the inside of the car and the outside of the car, a through hole is provided in the car body panel that separates the inside and outside of the car, and the cable can be routed through the through hole. A control cable is routed between the inside of the vehicle and the outside of the vehicle. At this time, a grommet as disclosed in Patent Document 1, for example, is used to prevent water from entering the vehicle from outside the vehicle through the through hole.

The grommet of Patent Document 1 includes a flexible grommet body (referred to as a grommet in Patent Document 1) in which an insertion hole through which a control cable is inserted, and a rigid grommet body attached to the grommet body. A grommet guide (referred to as a main body or the like in Patent Document 1) is provided. In a grommet, a grommet guide is inserted into a through hole provided in a vehicle body panel, and a seal portion of the grommet body (referred to as a periphery in Patent Document 1) and a claw portion of the grommet guide allow the penetration of the vehicle body panel. It is attached to the vehicle body panel by pinching the attachment part around the hole. The grommet prevents water from entering the vehicle from outside the vehicle by the sealing portion of the grommet body coming into contact with the outside surface of the mounting portion.

JP2009-68518A

In order to ensure a tight seal between the grommet and the car body panel when the grommet is attached to the car body panel, the outside surface of the car body panel attachment part that comes into contact with the seal part of the grommet body needs to be flat. There is. However, due to the necessity of providing other members such as brackets on the vehicle body panel, it may not be possible to secure a flat portion of sufficient length (width) from the periphery of the through hole. In such a case, in the grommet of Patent Document 1, since the seal portion extends outward from the grommet body at an angle, the abutment position of the seal portion exceeds the flat portion of the mounting portion. , it is difficult to ensure sufficient sealing performance. Therefore, in order to ensure a tight seal between the grommet and the vehicle body panel, it is necessary to place the seal part as far inside the grommet body as possible (through-hole hole side).

In the grommet of Patent Document 1, when attaching the grommet to a vehicle body panel, the claw portion of the grommet guide is bent in a direction perpendicular to the insertion direction, and the seal portion of the grommet body is bent in the insertion direction. It is necessary to insert the guide into the through hole. At this time, the closer the position of the seal part is to the position of the claw part, the greater the force required to deflect the seal part, which increases the insertion force required to insert the grommet guide into the through hole. . Therefore, as mentioned above, by arranging the seal part inside the grommet body to ensure a tight seal between the grommet and the vehicle body panel, the position of the seal part is closer to the position of the claw part of the grommet guide. This increases the insertion force required to insert the grommet guide into the through hole, making it difficult to attach the grommet to the vehicle body panel.

The present invention makes it easy to attach to an object such as a vehicle body panel even if the length of the flat part of the attachment part around the through hole from the periphery of the through hole is smaller than before. It is an object of the present invention to provide a grommet with excellent sealing performance between the grommet and the control cable assembly including the grommet and the control cable.

The grommet of the present invention is a grommet that is inserted into a through hole provided in an attachment target and attached to a mounting portion provided around the through hole, the grommet being a grommet that is inserted into an insertion hole through which an elongated member is inserted. and a grommet guide attached to the grommet body and inserted into the through hole, the grommet body having a base portion having the insertion hole, and when the grommet is inserted into the through hole. and a sealing part that abuts one surface of the mounting part, the grommet guide is attached to the grommet body and inserted into the through hole, and the grommet is inserted into the through hole. and a claw portion having a contact surface that contacts the other surface of the mounting portion, and the seal portion faces one surface of the mounting portion when the grommet is inserted into the through hole. and an inner lip and an outer lip extending from the support part to one surface of the attachment part, the inner lip being more radial outward from the center of the grommet body than the outer lip. The outer lip is positioned on the opposite side of the radial direction, and is formed to extend obliquely from the support part toward the opposite side of the radial direction, and the outer lip is positioned on a side in the radial direction than the inner lip. The inner lip and the outer lip are formed to extend obliquely from the support part toward the radial side, and the inner lip and the outer lip are formed so that the length of the inner lip in the extending direction of the inner lip is such that the length of the inner lip in the extending direction of the outer lip is The length of the outer lip is shorter than the length of the outer lip of the outer lip.

The control cable assembly of the present invention includes the grommet described above and the control cable that is the elongated member.

According to the present invention, even if the length of the flat part of the attachment part around the through hole provided in the object to be attached such as a car body panel from the periphery of the through hole is smaller than before, the attachment to the object to be attached is possible. It is possible to provide a grommet that is easy to install and has excellent sealing performance between the grommet and the control cable, and a control cable assembly that includes the grommet and the control cable.

However, the embodiments shown below are merely examples, and the grommet and control cable assembly of the present invention are not limited to the embodiments below.

The control cable assembly 1 of this embodiment includes a control cable 2 and a grommet 3, as shown in FIG. The control cable assembly 1 is handled with the control cable 2 and grommet 3 assembled together, and is used by being attached to an object such as a vehicle. However, the control cable 2 and the grommet 3 may be handled separately and assembled together to form the control cable assembly 1 when attached to the object to be attached.

The control cable assembly 1 is arranged, for example, between an operating part (not shown) such as a shift lever or a brake pedal of a vehicle and an operated part (not shown) such as a transmission or brake of a vehicle, and is It can be used as an operating force transmission mechanism that transmits an operating force between the and the operated part. The control cable assembly 1 has a grommet 3 attached to an attachment target P (for example, a vehicle body panel) that separates a space in which an operation part is provided (for example, indoors) and a space in which an operated part is provided (for example, outdoors). It is arranged between the operating section and the operated section with P in between. Note that the control cable assembly 1 is not limited to vehicles, and can be applied to applications other than vehicles as long as it transmits the operating force applied to the operating section to the operated section.

Note that in this specification, the other of the grommet 3 and the attachment target P may be described using a term that indicates a direction defined with respect to one of the grommet 3 and the attachment target P. In that case, the term indicating the direction means the corresponding direction of the other of the grommet 3 and the attachment target P when the grommet 3 is attached to the attachment target P. For example, regarding the attachment target P, the direction in which the through hole PO penetrates the attachment target P is defined as the penetration direction PD (see FIGS. 1 and 4). The term penetration direction PD is also used when describing the components of the grommet 3 attached to the attachment target P, but in that case, it is assumed that the grommet 3 is attached to the attachment target P or has been attached. means the direction in which the Furthermore, in a plane substantially perpendicular to the penetration direction PD, the direction from the center of the grommet body 4 of the grommet 3 to the outside is defined as a radial direction RD, and the direction from the outside to the center of the grommet body 4 is defined as the centripetal direction. CD (see Figure 4). The terms radial direction RD and centripetal direction CD are also used when describing other components of the grommet 3 and the attachment target P to which the grommet 3 is attached. Refers to the orientation in the attached state or in the assumed attached state.

The control cable 2 is wired between the operating section and the operated section, and transmits the operating force of the operating section to the operated section. As shown in FIG. 1, the control cable 2 is attached to the grommet 3 by being inserted into an insertion hole 411 provided in the grommet 3 and described later. By attaching the grommet 3 to the attachment target P, the control cable 2 can be connected to one side (lower side of the attachment target P in FIG. 1) and the other side (the lower side of the attachment target P in FIG. (above the target P). The control cable 2 is not particularly limited as long as it can transmit the operating force of the operating section to the operated section, but in this embodiment, as shown in FIG. It includes an outer casing 22 into which a cable 21 is inserted.

The inner cable 21 has one end directly or indirectly connected to the operating section and the other end directly or indirectly connected to the operated section, and applies operating force such as push or pull operation of the operating section to the operated section. introduce. The inner cable 21 is not particularly limited as long as it can transmit the operating force of the operating section to the operated section, and for example, a known push-pull cable or pull cable can be used.

The outer casing 22 has openings at both ends and a hollow section communicating the openings at both ends, and slidably accommodates the inner cable 21 in the hollow section. The outer casing 22 is routed from the operating section side to the operated section side via the through hole PO of the attachment target P, and guides the inner cable 21 along the routing route. The outer casing 22 is not particularly limited as long as the inner cable 21 can be inserted therein, and any known outer casing can be used.

As shown in FIG. 1, the grommet 3 is inserted into a through hole PO provided in an attachment target P such as a vehicle body panel, and is attached to a mounting portion PM provided around the through hole PO. The grommet 3 is inserted into a through hole PO provided in the attachment target P, and seals the through hole PO. Here, "sealing the through-hole PO" means that at least foreign matter such as water or dust passes through the through-hole PO between one side and the other side in the penetration direction PD with the mounting target P in between. It means to refrain from doing something. The grommet 3 guides the control cable 2 through the through hole PO between one side and the other side in the penetration direction PD across the attachment target P while sealing the through hole PO. In this embodiment, the grommet 3 is attached to the vehicle body panel (attachment target P) of the vehicle so as to seal the through hole PO, and is installed outdoors (on one side of the penetration direction PD with respect to the attachment target P, in FIG. , the lower side of the mounting target P) into the interior of the room (the other side of the mounting target P in the penetration direction PD, the upper side of the mounting target P in Figure 1), and also The control cable 2 is guided between the indoor and outdoor areas of the vehicle through the through hole PO. Note that the member guided through the through hole PO between one side and the other side in the penetration direction PD with the attachment target P in between is the control cable 2 in this embodiment; There are no particular limitations on any member as long as it is necessary to guide it between one side and the other side of the direction PD via the through hole PO. It may be a length member.

As shown in FIGS. 1 to 3, the grommet 3 includes a grommet main body 4 having an insertion hole 411 through which a control cable 2 (hereinafter also referred to as "elongated member 2"), which is an elongated member, is inserted, and a grommet main body 4. The grommet guide 5 is attached to the main body 4 and inserted into the through hole PO. The grommet 3 is inserted into the through hole PO of the mounting object P from one side (the lower side of the mounting object P in FIG. 1) to the other side (the upper side of the mounting object P in FIG. 1) in the penetration direction PD, The grommet body 4 and the grommet guide 5 sandwich the attachment part PM of the attachment target P in the penetration direction PD, thereby attaching it to the attachment target P.

As shown in FIGS. 1 to 3, the grommet body 4 includes a base portion 41 having an insertion hole 411, and a seal portion that comes into contact with one surface PMa of the mounting portion PM when the grommet 3 is inserted into the through hole PO. 42. The grommet main body 4 supports the elongated member 2 inserted into the insertion hole 411, and the seal portion 42 contacts one surface PMa of the mounting portion PM, so that the grommet body 4 supports the elongated member 2 inserted into the insertion hole 411, and the grommet body 4 supports the elongated member 2 inserted into the insertion hole 411. This prevents foreign substances such as water and dust from passing between one side and the other side through the through hole PO.

The base 41 supports the elongated member 2 inserted through the insertion hole 411 and closes the through hole PO of the attachment target P. The shape of the base 41 is not particularly limited as long as it can support the elongated member 2 and close the through hole PO of the attachment target P. In this embodiment, as shown in FIG. 1, the base 41 is formed to have a larger size than the through hole PO in a plane substantially perpendicular to the penetration direction PD in order to close the through hole PO of the attachment target P. ing. More specifically, the base 41 has a shape similar to that of the through hole PO in a plane substantially perpendicular to the penetration direction PD, and is formed into a substantially plate shape that is larger than the through hole PO.

As shown in FIG. 1, the insertion hole 411 provided in the base 41 is formed to penetrate the base 41 so as to communicate between one side and the other side in the penetration direction PD with the base 41 in between. The insertion hole 411 guides the elongated member 2 between one side and the other side in the penetration direction PD with the attachment target P interposed therebetween. In this embodiment, the insertion hole 411 extends across the cylindrical portion 45 provided in the base 41 on one side of the base 41 in the penetration direction PD (the lower side of the base 41 in FIG. 1), and On the other side of the penetration direction PD (above the base 41 in FIG. 1), it extends over a vibration absorbing portion 46, which will be described later (see FIG. 3). The grommet main body 4 can stably support the elongated member 2 because the insertion hole 411 extends not only to the base 41 but also to one side and the other side in the penetration direction PD with the base 41 interposed therebetween. The peripheral wall surrounding the insertion hole 411 may be provided with a protrusion (not shown) that projects radially inward of the insertion hole 411. As a result, sliding of the elongated member 2 within the insertion hole 411 is suppressed, and passage of foreign substances such as water and dust within the insertion hole 411 is suppressed.

When the grommet 3 is attached to the attachment target P, the seal portion 42 contacts one surface PMa of the attachment portion PM of the attachment target P, and seals the gap between the base portion 41 and one surface PMa of the attachment portion PM. Seal. Here, "sealing between the base 41 and one surface PMa of the mounting part PM" means at least between the base 41 and the other side in the penetration direction PD with the mounting target P in between. This means to suppress foreign matter such as water or dust from passing between the attachment part PM and one surface PMa. The seal portion 42 further comes into contact with one surface PMa of the attachment portion PM of the attachment target P, and suppresses the grommet main body 4 from moving to the other side in the penetration direction PD. The seal portion 42 is not particularly limited in its arrangement as long as it can seal between the base portion 41 and one surface PMa of the mounting portion PM and suppress movement of the grommet body 4 to the other side in the penetration direction PD. . In this embodiment, the seal portion 42 is formed in an annular shape along the outer periphery of the base portion 41 in a plane substantially perpendicular to the penetration direction PD, as shown in FIGS. 1 to 3. Details of the structure of the seal portion 42 will be described later.

In this embodiment, the grommet main body 4 includes leg portions 43 that support the seal portion 42, as shown in FIG. The leg portion 43 extends from an end of the outer circumference of the base portion 41 in a plane substantially perpendicular to the penetration direction PD toward one surface PMa of the attachment portion PM of the attachment target P, and extends along the outer circumference of the base portion 41. It is formed in a ring shape. The seal portion 42 is connected to a tip of the leg portion 43, which is an end portion on the opposite side to the base portion 41 in the penetration direction PD. However, the grommet main body 4 may not include the leg portions 43, and the seal portion 42 may be directly connected to the base portion 41 without being connected to the base portion 41 via the leg portions 43.

In this embodiment, the grommet main body 4 includes a groove 44 into which a later-described flange 53 of the grommet guide 5 can fit, as shown in FIG. The groove portion 44 is surrounded on three sides by the base portion 41, the seal portion 42, and the leg portion 43, and has a structure in which one side in the centripetal direction CD from the outside to the center of the grommet body 4 is open. The groove portion 44 is formed in an annular shape along the outer periphery of the grommet body 4 in a plane substantially perpendicular to the penetration direction PD. The grommet guide 5 is attached to the grommet body 4 by fitting the collar portion 53 into the groove portion 44, so that relative movement with respect to the grommet body 4 in the penetration direction PD and a direction substantially perpendicular to the penetration direction PD is suppressed. Ru. However, the grommet body 4 is not particularly limited as long as the grommet guide 5 is configured to be attachable so that the relative movement of the grommet guide 5 with respect to the grommet body 4 is suppressed, and the grommet body 4 may have a configuration other than the groove portion 44. You may be prepared.

In this embodiment, the grommet main body 4 includes a vibration absorbing portion 46 that stands upright from the base portion 41 toward the other side in the penetration direction PD, as shown in FIG. An insertion hole 411 provided in the base portion 41 is provided inside the vibration absorbing portion 46 to extend. The vibration absorber 46 absorbs vibrations received from the elongated member 2 inserted into the insertion hole 411 provided inside. A plurality of cavities extending along the penetration direction PD are arranged in a lattice pattern in the vibration absorbing section 46, thereby promoting weight reduction and suppression of deterioration of the vibration absorbing section 46. The insertion hole 411 through which the elongated member 2 is inserted is provided not only in the base 41 but also in the vibration absorbing part 46, so that the vibration generated in the elongated member 2 is transmitted from the elongated member 2 through the grommet main body 4 to the attachment point. The transmission to the target P is further suppressed. In particular, when the elongated member 2 is a control cable that transmits operating force, vibrations occur in the control cable due to the control cable itself, such as due to the transmission of the operating force, in addition to vibrations received from the outside. The control cable, which can generate large vibrations, is arranged not only in the base 41 but also in the vibration absorbing part 46 (and the cylindrical part 45), thereby further suppressing the vibration of the control cable from being transmitted to the attachment target P. be able to. However, the grommet main body 4 only needs to include at least the base portion 41 and the seal portion 42, and does not need to include the vibration absorbing portion 46.

The grommet main body 4 supports the elongated member 2 inserted into the insertion hole 411, and the seal portion 42 contacts one surface PMa of the mounting portion PM, so that the grommet body 4 supports the elongated member 2 inserted into the insertion hole 411, and the grommet body 4 supports the elongated member 2 inserted into the insertion hole 411. The material constituting the grommet main body 4 is not particularly limited as long as it can prevent foreign substances such as water and dust from passing through the through hole PO between one side and the other side. The grommet body 4 can be made of, for example, an elastic material. Since the grommet body 4 is made of an elastic material, the sealing performance of the seal portion 42 can be improved, and transmission of vibrations to the attachment target P via the grommet body 4 can be suppressed. The elastic material is not particularly limited, and examples include ethylene propylene diene rubber (EPDM), nitrile rubber (NBR), and chloroprene rubber (CR).

The grommet guide 5 is attached to the grommet body 4 and fixes the grommet body 4 to the attachment target P so as to suppress relative movement of the grommet body 4 with respect to the attachment target P. As shown in FIGS. 1 to 3, the grommet guide 5 has a main body portion 51 that is attached to the grommet body 4 and inserted into the through hole PO of the attachment target P, and when the grommet 3 is inserted into the through hole PO. and a claw portion 52 having an abutting surface 521 (see FIGS. 4 to 6) that abuts the other surface PMb of the mounting portion PM. When the grommet 3 is inserted into the through hole PO, a contact surface 521 of the claw portion 52 that contacts the other surface PMb of the mounting portion PM and a seal of the grommet body 4 that contacts one surface PMa of the mounting portion PM. By holding the attachment part PM in the penetration direction PD by the parts 42 (see FIG. 6), it is attached to the attachment target P.

When the main body part 51 is inserted into the through-hole PO of the attachment target P, it comes into contact with the opening edge of the through-hole PO (the end of the mounting part PM on the through-hole PO side), so that the main body part 51 moves in the through-hole direction PD. Relative movement with respect to the attachment target P in a substantially vertical direction is suppressed. Thereby, the main body part 51 suppresses relative movement of the grommet main body 4 attached to the main body part 51 with respect to the attachment target P in a direction substantially perpendicular to the penetration direction PD. When the main body part 51 is inserted into the through hole PO of the attachment object P, it is sufficient that the relative movement with respect to the attachment object P in a direction substantially perpendicular to the penetration direction PD of the through hole PO is suppressed, and its shape is not particularly limited. In this embodiment, as shown in FIG. 3, the main body portion 51 is formed in a cylindrical shape extending along the penetration direction PD, and has a size corresponding to the size of the through hole PO in a plane substantially perpendicular to the penetration direction PD. It is formed to have a size corresponding to or slightly smaller than the size of the through hole PO. In this embodiment, the main body part 51 is formed in a size such that the vibration absorbing part 46 provided in the grommet main body 4 is accommodated therein.

As shown in FIG. 6, when the grommet 3 is inserted into the through hole PO of the attachment target P, the claw portion 52 has a contact surface 521 that contacts the other surface PMb of the mounting portion PM. By engaging with the attachment portion PM in the penetration direction PD, the main body portion 51 is prevented from moving relative to the attachment target P to one side in the penetration direction PD. Thereby, when the grommet 3 is attached to the attachment target P, the main body part 51 suppresses the relative movement of the grommet body 4 attached to the main body part 51 to one side in the penetration direction PD with respect to the attachment target P. . The shape of the claw portion 52 is not particularly limited as long as it can come into contact with the other surface PMb of the attachment target P and suppress relative movement of the main body portion 51 to one side in the penetration direction PD. In this embodiment, the claw portion 52 is formed to protrude in the radial direction RD from the side surface of the main body portion 51 in a direction substantially perpendicular to the penetration direction PD, as shown in FIG. As shown in FIGS. 2 and 3, a plurality of claw portions 52 are provided on the side surface of the main body portion 51, but the size and number of the provided claw portions 52 may be determined as appropriate depending on the required engagement force. Can be set.

In this embodiment, as shown in FIGS. 5 and 6, the claw portion 52 has an engageable position (the position shown in FIG. 6) where it can engage with the mounting portion PM of the mounting object P, and a position where the claw portion 52 can engage with the mounting portion PM of the mounting object P. It is configured to be movable between an engagement release position (the position shown in FIG. 5) where engagement with part PM is released. More specifically, the claw portion 52 extends from a base end portion 522 located on the other side in the penetration direction PD to a distal end portion 523 located on one side in the penetration direction PD, and connects to the main body portion 51 at the base end portion 522. Cantilevered. The claw portion 52 is formed to be swingable in the radial direction RD and the centripetal direction CD with the base end portion 522 as the center. When the grommet 3 is inserted into the through hole PO of the attachment object P, the opening edge of the through hole PO of the attachment object P presses the claw portion 52 in the centripetal direction CD, so that the claw portion 52 is , deflects in the centripetal direction CD around the base end portion 522 and moves to the disengagement position (see FIG. 5). When the grommet 3 is further inserted into the through hole PO of the attachment target P, the tip portion 523 of the claw portion 52 crosses the opening edge of the through hole PO in the penetration direction PD, and the claw portion 52 restores the claw portion 52. The force restores it in the radial direction RD and moves it to the engageable position (see FIG. 6).

In this embodiment, as shown in FIG. 4, the claw portion 52 has an inclined portion 524 that extends from the base end portion 522 to one side in the penetration direction PD, and slopes toward the radial direction RD as the distance from the base end portion 522 increases. and a straight portion 525 extending substantially parallel to the penetration direction PD from the inclined portion 524 to the tip portion 523. When the grommet 3 is inserted into the through hole PO from one side to the other side in the penetration direction PD, the inclined part 524 of the claw part 52 passes through the through hole PO, and then the straight part 525 of the claw part 52 passes through the through hole PO. It passes through the through hole PO. When the inclined portion 524 passes through the through hole PO, the claw portion 52 receives a reaction force in the centripetal direction CD from the opening edge of the through hole PO while receiving a reaction force in the penetrating direction PD. . The claw portion 52, which receives the reaction force in the centripetal direction CD, bends in the centripetal direction CD and moves toward the disengagement position (see FIG. 5). When the straight portion 525 passes through the through hole PO (see FIG. 5), the claw portion 52 receives almost no reaction force from the opening edge of the through hole PO toward one side in the penetration direction PD. , and there is almost no further deflection in the centripetal direction CD. That is, in the initial stage of inserting the grommet 3 into the through-hole PO (the stage where the inclined part 524 passes through the through-hole PO), the claw part 52 receives a reaction force from the opening edge of the through-hole PO. Requires large insertion force to insert into PO. However, in the latter stage of inserting the grommet 3 into the through-hole PO (the stage where the straight part 525 passes through the through-hole PO), the claw part 52 receives almost no reaction force from the opening edge of the through-hole PO, so the grommet 3 into the through hole PO does not require a large insertion force. In the latter stage of inserting the grommet 3 into the through-hole PO, the seal portion 42 of the grommet main body 4 contacts one surface PMa of the mounting portion PM, and the grommet 3 closes to one surface of the mounting portion PM, as described below. It will receive a reaction force from PMa. However, even if the grommet 3 receives a reaction force from one surface PMa of the mounting part PM and the insertion force for inserting the grommet 3 into the through hole PO becomes large, at this later stage, as described above, the Since the reaction force received by the portion 52 is reduced, the insertion force for inserting the grommet 3 into the through hole PO can be suppressed to a small level.

The grommet guide 5 only needs to be attached to the grommet body 4 so that relative movement with respect to the grommet body 4 is suppressed, and the structure for attaching it to the grommet body 4 is not particularly limited. In this embodiment, the grommet guide 5 includes a flange portion 53 that can be engaged with the grommet main body 4, as shown in FIGS. 2 and 3. The collar portion 53 extends in the radial direction RD from the side surface of the main body portion 51 in a direction substantially perpendicular to the penetration direction PD at a position of the main body portion 51 adjacent to the base portion 41 of the grommet main body 4 in the penetration direction PD. It is formed in an annular shape along the outer periphery of the main body portion 51 in a plane substantially perpendicular to the direction PD. As shown in FIG. 4, the collar portion 53 is provided at a position facing the contact surface 521 of the claw portion 52 in the penetration direction PD. The grommet guide 5 is attached to the grommet body 4 by fitting the collar portion 53 provided on the body portion 51 into the groove portion 44 formed in the grommet body 4 . As shown in FIG. 6, the grommet guide 5 is configured such that the seal portion 42 of the grommet main body 4 is held between the collar portion 53 and the mounting portion PM of the attachment target P, and the claw portion 52 and the collar portion 53 The grommet body 4 is fixed to the attachment target P by sandwiching the attachment part PM between them. The flange portion 53 is located on the side of the seal portion 42 opposite to one surface PMa of the mounting portion PM in the penetration direction PD (lower side of the seal portion 42 in FIG. Since the seal portion 42 can be supported on one surface PMa of the PM, the sealing performance of the seal portion 42 can be improved.

As long as the grommet guide 5 can fix the grommet body 4 to the attachment target P so as to suppress the relative movement of the grommet body 4 with respect to the attachment target P, the material constituting the grommet guide 5 is not particularly limited. do not have. The grommet guide 5 can be made of, for example, a material with high rigidity, preferably a material with higher rigidity than the grommet body 4. Thereby, the grommet guide 5 can more firmly fix the grommet main body 4 to the attachment target P. Examples of materials having high rigidity include hard resins such as polyamide resin and metals such as stainless steel. In the embodiment, the grommet guide 5 is attached to the grommet main body 4 to be integrated, but the grommet main body 4 and the grommet guide 5 may be integrally molded.

Next, details of the structure of the seal portion 42 of the grommet main body 4 will be explained. As shown in FIGS. 4 to 6, when the grommet 3 is inserted into the through hole PO, the seal portion 42 is attached to a support portion 421 that faces one surface PMa of the attachment portion PM, and is attached from the support portion 421. It includes an inner lip 422 and an outer lip 423 extending toward one surface PMa of the portion PM.

As shown in FIG. 4, the support part 421 is connected to the base part 41 and supports the inner lip 422 and the outer lip 423, and also supports the inner lip 422 and the outer lip when the grommet 3 is attached to the attachment target P. 423 is pressed against one surface PMa of the mounting portion PM. The structure of the support part 421 is not particularly limited as long as it can support the inner lip 422 and the outer lip 423 and press the inner lip 422 and the outer lip 423 against one surface PMa of the attachment part PM. In this embodiment, the support portion 421 is formed in a substantially plate shape extending in a direction substantially perpendicular to the penetration direction PD, and is formed in an annular shape along the outer periphery of the base portion 41 . The support portion 421 is indirectly connected to the base portion 41 via the leg portions 43. The support portion 421 is connected to the distal end of the leg portion 43 so as to extend along the centripetal direction CD from the distal end of the leg portion 43, which is the end opposite to the base portion 41 in the penetration direction PD. The flange portion 53 of the grommet guide 5 is in contact with the surface of the support portion 421 on the base portion 41 side in the penetration direction PD (the lower surface of the support portion 421 in FIG. 4). Lateral deformation is suppressed by the flange portion 53. As a result, even if the seal portion 42 receives a reaction force from the mounting portion PM when the inner lip 422 and the outer lip 423 press one surface PMa of the mounting portion PM, the support portion 421 is prevented from deforming toward the base portion 41 side. Therefore, the pressing force of the inner lip 422 and the outer lip 423 can be increased, and the sealing performance of the seal portion 42 can be improved.

The inner lip 422 and the outer lip 423 are configured to come into contact with one surface PMa of the attachment part PM when the grommet 3 is attached to the attachment target P, as shown in FIG. The inner lip 422 and the outer lip 423 contact one surface PMa of the attachment part PM to seal between the base 41 and one surface PMa of the attachment part PM. Here, "sealing between the base 41 and one surface PMa of the mounting part PM" means at least between the base 41 and the other side in the penetration direction PD with the mounting target P in between. This means to suppress foreign matter such as water or dust from passing between the attachment part PM and one surface PMa. The inner lip 422 and the outer lip 423 are each connected to the support portion 421 and formed in an annular shape along the outer periphery of the base portion 41, as shown in FIGS. 2 to 4. The connection positions of the inner lip 422 and the outer lip 423 to the support part 421 are not particularly limited, but in this embodiment, as shown in FIG. It is connected to the tip of the leg 43 in the vicinity. As a result, the inner lip 422 and the outer lip 423 are supported not only by the support part 421 but also by the leg parts 43 in the penetrating direction PD, so that they can more reliably press one surface PMa of the attachment part PM. The sealing performance between the base portion 41 and one surface PMa of the attachment portion PM can be further improved.

As shown in FIGS. 3 and 4, the inner lip 422 is positioned on the opposite (centripetal direction CD) side of the radial direction RD outward from the center of the grommet body 4 than the outer lip 423, and extends from the support portion 421. It is formed to extend obliquely toward the opposite (centripetal direction CD) side of the radial direction RD. Further, the outer lip 423 is positioned closer to the radial direction RD than the inner lip 422, and is formed to extend obliquely from the support portion 421 toward the radial direction RD. In this way, the inner lip 422 is positioned closer to the centripetal direction CD than the outer lip 423, and further extends obliquely in the centripetal direction CD, so that the tip of the inner lip 422 is positioned on the centripetal direction CD side of the attachment part PM. That is, it can come into contact with the side closer to the through hole PO in the direction substantially perpendicular to the penetration direction PD (in the illustrated example, on the inner mounting portion PM1, which will be described later). Therefore, even if the length of the flat part of the attachment part PM around the through-hole PO provided in the attachment target P from the periphery of the through-hole PO becomes smaller than before, the tip of the inner lip 422 will not reach the attachment part PM. Since the base portion 41 can come into contact with one surface PMa of the mounting portion PM, it is possible to ensure sealing between the base portion 41 and one surface PMa of the mounting portion PM. Moreover, since the inner lip 422 and the outer lip 423 are inclined in opposite directions, it is possible to improve the direction of the grommet body 4 in the radial direction RD and the centripetal direction CD with respect to the attachment target P, compared to the case where the inner lip 422 and the outer lip 423 are inclined in the same direction. Relative movement in the direction of is also suppressed. In addition, since the inner lip 422 and the outer lip 423 are tilted in opposite directions, they function like a suction cup, thereby increasing the adhesion to one surface PMa of the mounting part PM and ensuring higher sealing performance. can do. Further, in this embodiment, the inner lip 422 and the outer lip 423 extend in opposite directions from each other around the same position of the support part 421 (near the tip of the leg part 43), so that one of the inner lips 422 and the outer lip 423 is in the penetration direction PD. When the other side is pressed toward the base 41 side, the other side is pressed toward the attachment part PM in the penetration direction PD, so they cooperate with each other to increase the pressing force on the attachment part PM, and the contact between the base 41 and one surface PMa of the attachment part PM is increased. The sealing performance between the parts can be improved.

As shown in FIGS. 3 and 4, the inner lip 422 and the outer lip 423 are such that the length of the inner lip 422 in the extending direction of the inner lip 422 is shorter than the length of the outer lip 423 in the extending direction of the outer lip 423. It is formed like this. Since the length of the inner lip 422 is shorter than the length of the outer lip 423, the pressing force exerted by the inner lip 422 and the outer lip 423 on one surface PMa of the mounting portion PM becomes smaller on the inner side (on the centripetal direction CD side). Thereby, the resistance force when inserting the grommet 3 into the through hole PO becomes small, and the insertion force for inserting the grommet 3 into the through hole PO can be kept small. Since the insertion force of the grommet 3 into the through hole PO can be kept small, the grommet 3 can be easily attached to the attachment target P. In particular, in this embodiment, since the support part 421 (and the collar part 53 of the grommet guide 5) is arranged on the base 41 side in the penetration direction PD, the inner lip 422 interferes on the base 41 side in the penetration direction PD. Compared to the outer lip 423 in which there is no member to deform, deformation is suppressed when the outer lip 423 receives a reaction force from the attachment part PM and is pressed toward the base part 41 in the penetration direction PD. In this case, the resistance force when inserting the grommet 3 into the through hole PO increases, but since the inner lip 422 is shorter than the outer lip 423, the resistance force on the inner side (on the centripetal direction CD side) becomes smaller, and the grommet 3 is inserted into the through hole PO. The insertion force for inserting into the through hole PO can be kept small.

As shown in FIG. 4, the inner lip 422 and the outer lip 423 are such that the width of the inner lip 422 in the direction perpendicular to the direction in which the inner lip 422 extends is the width of the outer lip in the direction perpendicular to the direction in which the outer lip 423 extends. It is preferable that the width is smaller than the width of 423. Since the width of the inner lip 422 is smaller than the width of the outer lip 423, the pressing force exerted by the inner lip 422 and the outer lip 423 on one surface PMa of the mounting portion PM becomes smaller on the inner side (on the centripetal direction CD side). Therefore, the resistance force when inserting the grommet 3 into the through hole PO becomes smaller, and the insertion force for inserting the grommet 3 into the through hole PO can be kept smaller. Since the insertion force of the grommet 3 into the through hole PO can be suppressed to a smaller level, the grommet 3 can be attached to the attachment target P more easily.

The arrangement of the inner lip 422 is not particularly limited as long as it is located at least on the inner side (on the centripetal direction CD side) than the outer lip 423 and is arranged so as to be in contact with one surface PMa of the attachment part PM. In this embodiment, the inner lip 422 is arranged such that the tip of the inner lip 422 is located closer to the radial direction RD than the contact surface 521 of the claw portion 52 of the grommet guide 5, as shown in FIG. Ru. By disposing the tip of the inner lip 422 on the side in the radial direction RD than the contact surface 521 of the claw portion 52, the inner lip 422 and the contact surface 521 of the claw portion 52 are separated when viewed in the penetration direction PD. do not overlap. Therefore, when the grommet 3 is inserted into the through hole PO, the inner lip 422 and the contact surface 521 of the claw portion 52 are prevented from interfering with each other in the penetration direction PD. Thereby, the resistance force that the attachment part PM receives from the claw part 52 and the inner lip 422 can be suppressed, and the insertion force required when inserting the grommet 3 into the through hole PO can be suppressed.

Further, in this embodiment, as shown in FIG. 4, the height position of the tip of the inner lip 422 with respect to the support part 421 in the penetration direction PD is the same as that of the claw part 52 with respect to the support part 421 in the penetration direction PD. The height position is the same as that of the contact surface 521 of the claw part 52 with respect to the support part 421, or the height position is on the support part 421 side with respect to the height position of the contact surface 521 of the claw part 52 with respect to the support part 421. The height position of the tip of the inner lip 422 from the support part 421 is the same as the height position from the support part 421 of the contact surface 521 of the claw part 52, or the inner lip is located on the support part 421 side. 422 and the claw portion 52 do not substantially overlap when viewed in a direction substantially perpendicular to the penetration direction PD. Therefore, when the grommet 3 is inserted into the through hole PO, the grommet 3 receives resistance from the claw portion 52 and then from the inner lip 422, and receives resistance from the claw portion 52 and the inner lip 422 almost simultaneously. Since the grommet 3 is not bent, the insertion force required when inserting the grommet 3 into the through hole PO can be suppressed.

The arrangement of the outer lip 423 is not particularly limited, as long as it is located at least on the outer side (on the RD side in the radial direction) than the inner lip 422 and in contact with one surface PMa of the attachment part PM. In this embodiment, as shown in FIG. 4, the height position of the tip of the outer lip 423 with respect to the support part 421 in the penetration direction PD is such that the height position of the tip of the outer lip 423 is in contact with the claw part 52 with respect to the support part 421 in the penetration direction PD. It is arranged at a height that exceeds the height of the contact surface 521 and is away from the support portion 421 . When the grommet 3 is attached to the attachment target P, the height position of the tip of the outer lip 423 from the support part 421 exceeds the height position of the contact surface 521 of the claw part 52 from the support part 421. , the attachment part PM is more firmly held between the contact surface 521 of the claw part 52 and the outer lip 423. Thereby, the grommet 3 is more firmly fixed to the attachment target P, and the sealing performance between one surface PMa of the attachment part PM and the outer lip 423 is further improved.

The grommet 3 of this embodiment can also be effectively applied to an attachment target P in which one surface PMa of the attachment part PM has a step. For example, the mounting part PM of the mounting target P shown in FIGS. 1 and 4 has an inner mounting part PM1 adjacent to the through hole PO in the radial direction RD, and an inner mounting part PM1 that is spaced apart from the through hole PO in the radial direction RD. It has an outer attachment part PM2 adjacent to the part PM1. The inner mounting portion PM1 and the outer mounting portion PM2 are each formed in an annular shape along the outer periphery of the through hole PO in a plane substantially perpendicular to the penetration direction PD. direction (CD side). The inner mounting portion PM1 and the outer mounting portion PM2 are such that when the grommet 3 is inserted into the through hole PO, one surface PMa1 of the inner mounting portion PM1 is located closer to the support portion 421 than one surface PMa2 of the outer mounting portion PM2. It is formed to do so. In other words, a step is formed between one surface PMa1 of the inner mounting portion PM1 and one surface PMa2 of the outer mounting portion PM2, and one surface PMa1 of the inner mounting portion PM1 is lower than one surface PMa2 of the outer mounting portion PM2. is also located on one side of the penetration direction PD.

As shown in FIG. 6, the grommet 3 applied to such a mounting target P has an inner lip 422 and an outer lip 423, respectively, when the grommet 3 is inserted into the through hole PO. It is preferable to arrange it so that it may contact|abut one surface PMa1 of PM1 and one surface PMa2 of outer attachment part PM2. The inner lip 422, which has a shorter length than the outer lip 423, comes into contact with one surface PMa1 of the inner mounting portion PM1, which is located on one side in the penetration direction PD than the one surface PMa2 of the outer mounting portion PM2. While ensuring the sealing between one surface PMa1 of the mounting portion PM1 and the inner lip 422, the resistance force that the mounting portion PM receives from the inner lip 422 can be suppressed. Therefore, the insertion force required when inserting the grommet 3 into the through hole PO can be suppressed. Further, the outer lip 423 is longer than the inner lip 422, but comes into contact with one surface PMa2 of the outer mounting portion PM2, which is located on the other side in the penetration direction PD than one surface PMa1 of the inner mounting portion PM1. The amount of deflection can be suppressed compared to when it comes into contact with a surface with no surface. Thereby, the resistance force that the attachment part PM receives from the outer lip 423 can be suppressed, so that the insertion force required when inserting the grommet 3 into the through hole PO can be suppressed.

Next, the operation of attaching the grommet 3 of this embodiment to the attachment target P will be explained. However, the attachment operation described below is just an example, and the grommet attachment operation of the present invention is not limited to the following example.

The control cable 2, which is a long member, is attached to the grommet 3 by being inserted into an insertion hole 411 provided in the grommet main body 4. As shown in FIGS. 4 to 6, the grommet 3 to which the control cable 2 is attached is inserted into the through hole PO of the attachment target P such as a vehicle body panel on one side of the penetration direction PD (for example, outdoors, in FIG. It is inserted from the lower side of the object P toward the other side (for example, indoors, the upper side of the object P in FIG. 4). When the grommet 3 is inserted into the through hole PO, first, the grommet guide 5 of the grommet 3 enters the through hole PO from the other end in the penetration direction PD. As the grommet guide 5 advances in the through hole PO along the penetration direction PD, the opening edge of the through hole PO provided in the attachment target P becomes a claw portion 52 that protrudes from the main body portion 51 of the grommet guide 5 in the radial direction RD. , and presses the claw portion 52 in the centripetal direction CD. The claw portion 52 pressed in the centripetal direction CD is bent in the centripetal direction CD and moves to the disengagement position (see FIG. 5).

When the grommet 3 is further inserted into the through hole PO, the claw portion 52 finishes passing through the through hole PO and crosses the opening edge of the through hole PO. The claw portion 52 that has crossed the opening edge of the through-hole PO is no longer pressed in the centripetal direction CD by the opening edge of the through-hole PO, so it is displaced in the radial direction RD by its own restoring force to the engagement position. (See Figure 6). On the other hand, the inner lip 422 and the outer lip 423 of the seal portion 42 of the grommet main body 4 come into contact with one surface PMa of the attachment part PM of the attachment target P. Here, the inner lip 422 is positioned in the centripetal direction CD than the outer lip 423, and further extends obliquely in the centripetal direction CD, so that the tip of the inner lip 422 is on the side closer to the through hole PO of the attachment part PM. can come into contact with. Therefore, even if the length of the flat part of the attachment part PM around the through-hole PO provided in the attachment target P from the periphery of the through-hole PO becomes smaller than before, the tip of the inner lip 422 will not reach the attachment part PM. can be brought into contact with one surface PMa of. Thereby, it is possible to ensure sealing between the base portion 41 and one surface PMa of the mounting portion PM. Furthermore, in this embodiment, the length of the inner lip 422 is shorter than the length of the outer lip 423. As a result, the pressing force exerted by the inner lip 422 and the outer lip 423 on one surface PMa of the mounting portion PM becomes smaller on the inner side (on the centripetal direction CD side). Therefore, the resistance force when inserting the grommet 3 into the through hole PO is reduced, and the insertion force for inserting the grommet 3 into the through hole PO can be kept small. Since the insertion force of the grommet 3 into the through hole PO can be kept small, the grommet 3 can be easily attached to the attachment target P.

In the example shown in FIGS. 4 to 6, there is a step on one surface PMa of the mounting portion PM, and there is a step on one surface PMa1 of the inner mounting portion PM1, which is relatively located on one side of the penetration direction PD. The short inner lip 422 abuts, and the relatively long outer lip 423 abuts one surface PMa2 of the outer mounting portion PM2, which is relatively located on the other side in the penetration direction PD (see FIG. 6). When both the inner lip 422 and the outer lip 423 are provided, the grommet 3 receives resistance from both the inner lip 422 and the outer lip 423 when the grommet 3 is inserted into the through hole PO, compared to the case where either one is provided. This increases the insertion force for inserting the grommet 3 into the through hole PO. However, because the short inner lip 422 contacts one surface PMa1 of the inner mounting portion PM1 and the long outer lip 423 contacts one surface PMa2 of the outer mounting portion PM2, both the inner lip 422 and the outer lip 423 The amount of deflection can be suppressed, and the insertion force for inserting the grommet 3 into the through hole PO can be suppressed. Therefore, the grommet 3 can be easily attached to the attachment target P.

As shown in FIG. 6, when the claw portion 52 moves to the engageable position, the contact surface 521 of the claw portion 52 contacts the other surface PMb of the attachment portion PM. The contact surface 521 of the claw portion 52 that contacts the other surface PMb of the mounting portion PM, and the inner lip 422 and outer lip 423 of the seal portion 42 that contacts the one surface PMa of the mounting portion PM, make the mounting portion PM are clamped in the penetration direction PD, and the grommet 3 is fixed to the attachment target P.
