Description

  The present invention relates to a cover member, and more particularly, to a cover member that can prevent intrusion of ice and snow into an internal space from an opening of a member member through which one end side of a connecting member is inserted.

  For example, in a horizontally installed FF vehicle, the left and right sides of the engine are supported by the vehicle body frame via the engine mount, and the lower part of the engine is connected to the suspension member (member member) via the torque rod (connecting member). It is general (patent document 1).

  In this case, in the configuration in which one end side of the torque rod is connected to the lower surface of the suspension member, the minimum ground clearance of the automobile is reduced. Therefore, a technique is known in which an opening is formed in the engine side surface of the suspension member, and one end side of the torque rod is inserted into the internal space from the opening and connected to the suspension member, thereby suppressing a decrease in the minimum ground clearance. (Patent Document 2).

Japanese Unexamined Patent Publication No. 2007-331645 (for example, paragraph [0026] and FIG. 2) Japanese Patent Laying-Open No. 2007-253642 (for example, paragraph [0035], FIGS. 1 and 2)

  Here, in the latter technique described above, in order to avoid interference when the torque rod is swung with the displacement of the engine, the opening of the suspension member is enlarged by the amount of the swing of the torque rod, and the torque rod A gap is formed between the two. However, when the gap is formed in this way, there is a problem that ice and snow scattered by the wheels enter into the internal space from the opening of the suspension member when traveling on a snowy road in winter. When the ice and snow that has entered is frozen, the swing of the torque rod is hindered, and the roll displacement of the engine cannot be regulated. Or when a torque rod crushes ice and snow, generation | occurrence | production of abnormal noise is caused.

  The present invention has been made to solve the above-described problems, and provides a cover member that can suppress the intrusion of ice and snow into the internal space from the opening of the member member through which one end side of the connecting member is inserted. The purpose is to do.

  In order to achieve this object, a cover member according to claim 1 is a member member whose internal space is communicated to the outside through an opening formed on one side surface, and from the opening of the member member into the internal space. The inserted one end side is mounted on a vehicle having a connecting member connected to the member member, and prevents ice and snow from entering the internal space from the opening, and is made of a rubber-like elastic material. A main body part; and a first projecting piece and a second projecting piece formed integrally with the main body part and projecting from an outer edge of the main body part, the main body part for inserting the connecting member An insertion hole that is formed in an opening, and a dividing path that extends from the inner edge of the insertion hole to the outer edge of the main body portion and between the first protrusion and the second protrusion, and divides the main body. The first projecting piece and the second projecting piece are formed of the member member. A first hole and a second hole are formed so that an engaging pin engaged with one side surface can be inserted, and is mounted on the vehicle in a state where the first projecting piece and the second projecting piece are overlapped with each other. At the same time, in the state of being mounted on the vehicle, the hole positions of the first hole and the second hole are matched.

  The cover member according to claim 2 is the cover member according to claim 1, wherein the main body portion is opposed to the one side surface of the member member with a predetermined interval, and the insertion hole and the dividing path are formed. A spacing portion that surrounds the spacing portion and abuts against one side surface of the member member, and a connection wall that connects the abutting portion and the spacing portion. The slit part extended toward the said connection wall from the inner edge of the said through-hole which becomes an other side with a parting path is provided.

  The cover member according to a third aspect is the cover member according to the second aspect, wherein the spacing portion projects from a surface facing one side surface of the member member and extends along the outer edge of the insertion hole. Provided with a rib-shaped rib portion.

  The cover member according to claim 4 is the cover member according to claim 3, wherein the insertion hole of the main body is formed in a rectangular shape, and the connection wall is curved in a convex arc shape toward the separation portion. The curved wall portion is positioned to face a corner portion of the insertion hole adjacent to the slit portion, and the separating portion faces one side surface of the member member. A flat surface is formed between the curved wall portion of the surface and a corner portion of the insertion hole.

  According to the cover member of the first aspect, the main body portion includes the main body portion formed of the rubber-like elastic material, and the main body portion includes the insertion hole formed to open the connection member. With the connecting member inserted through the insertion hole, the body portion is attached to the opening of the member member, so that the opening of the member member can be closed. As a result, ice and snow from the opening of the member member into the internal space. There is an effect that intrusion can be suppressed. Therefore, it is possible to avoid beforehand that the ice and snow that has entered the internal space are frozen and the swinging of the connecting member is prevented. Similarly, the generation of abnormal noise when the rocking connecting member crushes ice and snow can be avoided in advance.

  In this case, since the main body is made of a rubber-like elastic material, when the connecting member swings, the main body can be deformed along with the swing, and as a result, the connecting member swings. There is an effect that movement can be secured. Therefore, since the gap between the insertion hole of the main body and the connecting member can be reduced, it is possible to easily suppress the intrusion of ice and snow from the opening of the member member into the internal space.

  Moreover, since the main body part includes a dividing path that extends from the inner edge of the insertion hole to the outer edge of the main body part and divides the main body part, the connecting member passes through the dividing path of the main body part so that the connecting member passes through the insertion hole of the main body part. The state inserted through can be easily formed. Therefore, there is an effect that the cover member can be easily attached to the vehicle.

  Further, the first and second protrusions are provided so as to protrude from the outer edge of the main body portion and sandwich the dividing path, and the first and second protrusions are engaged with one side surface of the member member. The first and second projections are provided so that the engagement pin can be inserted, and the first projection and the second projection are overlapped with each other to narrow the width of the dividing path. In addition, since the hole positions of the first hole and the second hole coincide with each other, by inserting one engaging pin into the first hole and the second hole, Two members with two projecting pieces can be engaged with one side surface of the member member at a time by one engaging pin. Therefore, the number of engagement pins and the insertion work process are reduced as compared with the case where the engagement pins are inserted through the first hole of the first protrusion and the second hole of the second protrusion. Therefore, there is an effect that it is possible to reduce the part cost and the work cost.

  According to the cover member of Claim 2, in addition to the effect which the cover member of Claim 1 produces | generates, a main-body part opposes with a predetermined space | interval between one side surface of a member member, and an insertion hole and a dividing path The contact portion of the main body portion is provided with a separation portion that is formed, a contact portion that surrounds the separation portion and is in contact with one side surface of the member member, and a connection wall that connects the contact portion and the separation portion. There is an effect that the adhesion between the portion and one side surface of the member member can be secured, and the intrusion of ice and snow can be more reliably suppressed.

  That is, when the main body is formed as a single plate, when the main body is deformed by being pressed by the swinging connecting member, a part of the main body is lifted from one side surface of the member member along with the deformation. The formation of the gap makes it easier for ice and snow to enter. On the other hand, as described above, the connecting member is swung by connecting the separating portion and the abutting portion with the connection wall and changing the positional relationship between the separating portion and the abutting portion. In this case, the swinging can be absorbed by the deformation of the separation portion and the connection wall, and the contact portion can be prevented from floating from one side surface of the member member. As a result, the adhesion between the contact portion and one side surface of the member member can be ensured, and the intrusion of ice and snow can be more reliably suppressed.

  In addition, since the separation portion includes a slit portion extending from the inner edge of the insertion hole on the side opposite to the dividing path toward the connection wall, the first protrusion piece and the second protrusion piece are divided by the space by the slit portion. The deformation | transformation at the time of superposing | stacking can be ensured, and generation | occurrence | production of the surplus can be suppressed. Therefore, since it can suppress that a contact part lifts from one side of a member member, the adhesion between a contact part and one side of a member member can be secured, and intrusion of ice and snow can be controlled more certainly. There is an effect that can be done.

  Furthermore, since the separating portion includes the slit portion, the separating portion can be easily deformed. Therefore, when the connecting member swings, the swing is mainly absorbed by the deformation of the separating portion, It can suppress that a contact part lifts from one side of a member member. As a result, the adhesion between the contact portion and one side surface of the member member can be ensured, and the intrusion of ice and snow can be more reliably suppressed.

  According to the cover member of the third aspect, in addition to the effect produced by the cover member according to the second aspect, since the separation portion includes the rib-shaped rib portion extending along the outer edge of the insertion hole, the separation portion There is an effect that the intrusion of ice and snow can be suppressed. In other words, the spacing portion is a portion where the slit portion is provided with a predetermined interval between one side surface of the member member and the slit portion is extended. Therefore, the spacing portion in the vicinity of the slit portion is bent, and the bent portion is Easy to sag. Therefore, a slit part opens and invites invasion of ice and snow. On the other hand, as described above, if the rigidity of the separation portion can be ensured by the rib-shaped rib portion, the separation portion in the vicinity of the slit portion is hardly hung down, and the opening of the slit portion can be suppressed. Therefore, the entry of ice and snow can be suppressed accordingly.

  Further, since the rib portion is protruded on the surface facing the one side surface of the member member of the separation portion, it is possible to prevent the rib portion from being worn or chipped by collision with ice and snow. Thereby, since the lifetime of a rib part can be improved, there exists an effect that it can suppress over a long period that a slit part opens, ie, the invasion of snow and snow.

  According to the cover member of the fourth aspect, in addition to the effect produced by the cover member according to the third aspect, the connection wall includes a curved wall portion that is formed in a convex arc shape toward the separation portion, Since the curved wall portion is positioned opposite to the corner portion of the insertion hole adjacent to the rib portion, the contact portion in the vicinity of the corner portion of the insertion hole adjacent to the slit portion can be prevented from floating from one side surface of the member member. Therefore, there is an effect that the adhesion between the abutting portion and one side surface of the member member can be ensured and the intrusion of ice and snow can be more reliably suppressed.

  That is, the vicinity of the corner of the insertion hole adjacent to the slit portion has a large degree of deformation when the first protrusion and the second protrusion are overlapped, and the excess thickness tends to concentrate. If the opposing connecting wall (curved wall portion) is curved in a convex arc shape toward the separating portion, it is possible to secure the deformability of the curved wall portion and to suppress the occurrence of excess wall. it can. Further, the curved wall portion is formed in a convex arc shape at a position facing the corner portion of the insertion hole, so that the distance between the corner portion of the insertion hole and the curved wall portion (that is, the separation portion). Therefore, it is possible to secure the deformability of the separating portion in the vicinity of the corner portion of the insertion hole and to suppress the occurrence of surplus. As a result, the contact portion in the vicinity of the corner portion of the insertion hole adjacent to the slit portion can be prevented from floating from one side surface of the member member, so that adhesion between the contact portion and one side surface of the member member is ensured. Thus, the intrusion of ice and snow can be more reliably suppressed.

  Further, since the spacing portion is formed in a flat surface between the curved wall portion of the surface facing the one side surface of the member member and the corner portion of the insertion hole, the corner of the insertion hole adjacent to the slit portion is formed. It is possible to secure the deformability of the separation part in the vicinity of the part and suppress the occurrence of surplus. Therefore, this also prevents the contact portion in the vicinity of the corner portion of the insertion hole adjacent to the slit portion from floating from one side surface of the member member, so that the contact between the contact portion and one side surface of the member member is reduced. The invasion of ice and snow can be more reliably suppressed by securing the property.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a cover member 1 according to an embodiment of the present invention, illustrating a state where the cover member 1 is mounted on a surface F of a suspension member SM.

  The suspension member SM is a member that supports the wheel via the lower arm and the shock absorber while being erected on the left and right (left and right in FIG. 1) side members (not shown). An opening h is formed in the surface F of the suspension member SM facing the engine, and one end of the torque rod TR is inserted into the opening h. The torque rod TR is connected to the suspension member SM at one end side (one of vibration isolation members B described later) inserted into the internal space from the opening h, and the other end side (the other side of the vibration isolation member B) is the engine. Connected to

  As shown in FIG. 1, the torque rod TR has a phase of both vibration isolation members B of 90 degrees with respect to a pair of vibration isolation members B in which the inner cylinder b1 and the outer cylinder b2 are connected by a rubber-like elastic material b3. It is a vibration isolator formed by connecting the outer cylinders b2 with the rod member R while shifting. The outer shape (width and height dimensions) of the rod R is made smaller than the diameter of the outer cylinder b2.

  Here, when the engine is displaced along with acceleration / deceleration or turning of the vehicle, the torque rod TR is swung along with the displacement of the engine. Therefore, a gap is formed between the inner edge of the opening h of the suspension member SM and the outer shape (outer surface) of the torque rod TR to allow the torque rod TR to swing and avoid interference. That is, the opening h is formed as an opening having a rectangular shape in front view in which the above-described gap is added to the outer shape of the vibration isolator B.

  As shown in FIG. 1, a locking hook L projects from the surface F of the suspension member SM. The locking hook L is a member for locking the locking hole 121 of the cover member 1 and is formed in an L shape in side view.

  As shown in FIG. 1, the cover member 1 is a member formed from a self-lubricating rubber-like elastic material. The torque rod TR is inserted into the insertion hole 111 while the locking hole 121 is locked to the locking hook L. Is inserted, and the engagement pin P is engaged on the lower side (lower side in FIG. 1), so that the opening F of the suspension member SM is covered and attached to the surface F. Thereby, it is possible to prevent ice and snow from entering the internal space from the opening h.

  Next, the detailed configuration of the cover member 1 will be described with reference to FIGS. 2 to 4. 2 and 3 are perspective views of the cover member 1, and FIG. 4 is a rear view of the cover member 1. 2 to 4 show a state (product state) before the cover member 1 is mounted on the vehicle. 2 shows the front side of the cover member 1, and FIG. 3 shows the back side of the cover member 1.

  As shown in FIGS. 2 to 4, the cover member 1 includes a main body 100, a first protrusion 201 and a second protrusion that are formed integrally with the main body 100 and project from the outer edge of the main body 100. And a piece 202. The main body 100, the first projecting piece 201, and the second projecting piece 202 are integrally formed from self-lubricating rubber. Therefore, generation | occurrence | production of the abnormal noise at the time of the main-body part 100 and torque rod TR (refer FIG. 1) contacting and sliding can be suppressed.

  As shown in FIGS. 2 to 4, when the main body 100 faces the surface F of the suspension member SM with a predetermined gap, the main body 100 surrounds the space 110 and the surface F of the suspension member SM. A contact portion 120 to be contacted, and a connection wall 130 connecting the contact portion 120 and the separation portion 110 are provided.

  As shown in FIGS. 2 to 4, the separation portion 110 is a portion formed as a plate-like body having a constant thickness. The body portion 100 extends from an insertion hole 111 formed in the center and an inner edge of the insertion hole 111. A dividing path 112 extending to the outer edge of the insertion hole 111 and a slit 113 extending from the inner edge of the insertion hole 111 to the middle of the separating portion are provided.

  The insertion hole 111 is an opening through which the torque rod TR is inserted. As shown in FIGS. 2 to 4, the three sides below the dividing path 112 and the slit 113 (lower side in FIG. 4) intersect each other vertically. On the other hand, it is formed in a deformed substantially rectangular shape in which three sides above the dividing path 112 and the slit 113 (upper side in FIG. 4) cross each other obliquely.

  Here, in the product state shown in FIGS. 2 to 4, the insertion hole 111 is formed in an opening smaller than the diameter of the outer cylinder b <b> 2 in the vibration-proof member B of the torque rod TR. Therefore, the operation of inserting the torque rod TR into the insertion hole 111 is performed by opening a dividing path 112 described later and fitting the rod R of the torque rod TR into the insertion hole 111 from the opened portion (the dividing path 112). Done. However, the insertion hole 111 in the product state may be formed in an opening larger than the diameter of the outer cylinder b2 in the vibration isolating member B of the torque rod TR. In this case, as will be described later, one end side of the torque rod TR (anti-vibration member) is secured to the cover member 1 in a state where the locking hole 121 is locked by the locking hook L and is suspended from the suspension member SM. B) can be easily inserted through the insertion hole 111.

  In the state of being mounted on the suspension member SM, the first projecting piece 201 and the second projecting piece 202 are overlapped as will be described later, and the main body 100 is deformed in the direction in which the width of the dividing path 112 and the slit 113 is reduced. Thereby, the shape of the insertion hole 111 is formed in a substantially rectangular shape. As a result, the insertion hole 111 is an opening that is slightly larger than the outer shape of the rod R of the torque rod TR, so that the intrusion of ice and snow into the opening h of the suspension member SM can be suppressed (see FIG. 1).

  As shown in FIG. 2 to FIG. 4, the dividing path 112 is a part that is notched and formed in the separation portion 110, and extends from the inner edge of the insertion hole 111 to the outer edge of the main body portion 100 (the contact portion 120). That is, the main body portion 100 is divided), and the width (the vertical dimension in FIG. 4) increases from the inner edge of the insertion hole 111 toward the outer edge of the main body portion 100.

  As shown in FIGS. 2 to 4, one side (for example, the upper side in FIG. 4) of the dividing path 112 is formed in parallel to one side (the upper side in FIG. 4) of the opposing sides of the insertion hole 111. The other side (lower side in FIG. 4) of the dividing path 112 is formed in parallel to the other side (lower side in FIG. 4) of the opposite sides of the insertion hole 111. As a result, in the mounted state on the suspension member SM, the insertion hole 111 has a substantially rectangular shape when viewed from the front, and the dividing path 112 is in a state where both sides are close to each other, so that intrusion of ice and snow can be prevented (see FIG. 1). .

  As shown in FIGS. 2 to 4, the dividing path 112 is an outer edge of the main body portion 100 (the contact portion 120) and extends between the first projecting piece 201 and the second projecting piece 202. Therefore, when the torque rod TR is inserted into the insertion hole 111 of the cover member 1, in addition to the operation method of directly inserting one end side (vibration isolation member B) of the torque rod TR into the insertion hole 111, A method of expanding the dividing path 112 by displacing the first protruding piece 201 and the second protruding piece 202 away from each other and passing the rod R of the torque rod TR to the insertion hole 111 through the dividing path 112. Can also be adopted.

  As shown in FIG. 2 to FIG. 4, the slit portion 113 is a portion that is notched in the separation portion 110, and is halfway through the separation portion 110 from the inner edge of the insertion hole 111 toward the main body portion 100 (connection wall 130). It is extended to. The slit portion 113 is a side opposite to a side (an inner edge of the insertion hole 111 on the right side in FIG. 4) where the dividing path 112 is formed on the two opposite sides of the insertion hole 111 (the left side in FIG. 4 of the insertion hole 111). And extends substantially parallel to the dividing path 112 from a position that is above the dividing path 112 in the gravitational direction (see the upper side of FIG. 8 and FIG. 8) in the mounted state.

  As shown in FIG. 4, the slit portion 113 has a maximum width (the vertical dimension in FIG. 4) on the inner edge side of the insertion hole 111, and is formed in a tapered shape that becomes narrower toward the connection wall 130. At the terminal end (left end in FIG. 4), it is formed in an arc shape. As a result, as will be described later, both the sides of the slit portion 113 are brought closer to each other while ensuring the deformability when the first projecting piece 201 and the second projecting piece 202 are overlapped, and suppressing the occurrence of surplus. Can do. As a result, the contact portion 120 is prevented from floating from the surface F (see FIG. 1) of the suspension member SM, and the adhering snow is intruded between the contact portion 120 and the surface F by ensuring the adhesion. While suppressing this, it is possible to reduce the opening area of the slit portion 113 and to prevent ice and snow from directly entering from the slit portion 113.

  As shown in FIGS. 3 and 4, the separation portion 110 includes a rib portion 114 that protrudes from a surface (a front side surface in FIG. 4) that faces the surface F (see FIG. 1) of the suspension member SM. The rib portion 114 is a protrusion for increasing the rigidity of the separation portion 110, and extends along the inner edge of the insertion hole 111. Thereby, the rigidity of the separation part 110 can be ensured and intrusion of ice and snow can be suppressed.

  That is, the separation portion 110 is a portion that is disposed at a predetermined interval from the surface F (see FIG. 1) of the suspension member SM and that the slit portion 113 is extended. (A portion formed between one side of the slit 113 and the inner edge of the insertion hole 111, and a portion that is lower in the weight direction than the slit 113 when mounted on the vehicle, hereinafter referred to as “portion 110a”) is gravity. It is bent by the action of, and the bent part tends to hang down. For this reason, the slit 113 is opened, and intrusion of ice and snow is caused.

  On the other hand, as described above, if the rigidity of the portion 110a of the separating portion 110 can be secured by the rib-shaped rib portion 114, the portion 110a is hardly hung down and the slit portion 113 is prevented from opening. Therefore, the entry of ice and snow can be suppressed accordingly.

  On the other hand, as shown in FIG. 3 and FIG. 4, the separation portion 110 is located on the opposite side of the above-described portion 110 a with the slit 113 (between one side of the slit 113 and the inner edge of the insertion hole 111. The rib portion 114 is not provided (ie, a flat surface) in a portion formed in the above-described portion and located in the weight direction above the slit 113 when mounted on the vehicle (hereinafter referred to as “portion 110b”). It is a configuration.

  That is, since the portion 110b of the separation portion 110 is a portion that is not easily bent by the action of gravity, the material cost can be reduced by omitting the rib portion 114, and the product cost can be reduced accordingly. Moreover, when the 1st protrusion piece 201 and the 2nd protrusion piece 202 are piled up so that it may mention later, the deformation | transformation property of the site | part 110b vicinity can be ensured and generation | occurrence | production of a surplus can be suppressed. As a result, the contact portion 120 in the vicinity of the portion 110b is prevented from floating from the surface F (see FIG. 1) of the suspension member SM, and the adhesion between the contact portion 120 and the surface F is ensured. Intrusion of ice and snow can be suppressed.

  As shown in FIGS. 3 and 4, the separation portion 110 is located on the opposite side of the portion 110 b with the insertion hole 111 therebetween (between one side of the dividing path 112 and the inner edge of the insertion hole 111. A rib portion 114 is provided in a portion that is formed and is a portion that is above the dividing path 112 in the weight direction when mounted on the vehicle (hereinafter referred to as “portion 110c”). Thereby, since the rigidity of the site | part 110c can be improved, it can suppress that the dividing path 112 opens, and can suppress the penetration | invasion of ice and snow by that much.

  The rib portion 114 is projected from the surface facing the surface F (see FIG. 1) of the suspension member SM of the separation portion 110. Can be suppressed. As a result, the life of the rib portion 114 can be improved, so that the opening of the dividing path 113 (part 110c) and the slit part 112 (parts 110a, 110b), that is, the intrusion of ice and snow can be suppressed over a long period. can do.

  As shown in FIGS. 3 and 4, the separating portion 110 is adjacent to the portions 110 a and 110 b and is located on the far side (left side in FIG. 4) in the extending direction of the slit portion 113 (hereinafter referred to as “part 110 d”). ) Projecting outward (in the direction opposite to the insertion hole 111) and curved in an arc shape. When the first projecting piece 201 and the second projecting piece 201 are overlapped with each other by this region 110d, it is possible to secure the deformability in the vicinity of the slit portion 113 and suppress the occurrence of surplus. Therefore, since the contact part 120 in the vicinity of the slit part 113 can be prevented from being lifted from the surface F of the suspension member SM, the adhesion can be ensured and the intrusion of ice and snow can be suppressed.

  The contact portion 120 is a portion where the bottom surface (the front side surface in FIG. 4) is in contact with the surface F of the suspension member SM (see FIG. 1), and as shown in FIGS. Is formed continuously at a position surrounding the. Although a part of the contact portion 120 is divided by the dividing path 112, as described later, the first projecting piece 201 and the second projecting piece 202 overlap each other at the dividing position by the dividing path 112. In the state where the suspension member SM is mounted on the surface F (see FIG. 1), the gap between the contact portion 120 and the surface F and the ice and snow from the lateral direction (direction parallel to the surface F) are superimposed. Intrusion can be suppressed.

  As shown in FIGS. 2 to 4, the contact portion 120 is formed with a locking hole 121 through which the locking hook F (see FIG. 1) is inserted. The locking hole 121 is formed in a shape in which slit-shaped notches are extended from the bottom side (the lower side in FIG. 4) of the hole having a substantially rectangular shape in front view to both sides (the left-right direction in FIG. 4). As a result, the cover member 1 is deformed by collision of scattered ice and snow or swinging of the torque rod TR during use in a state of being locked to the locking hook F, and the vicinity of the locking hole 121 is subjected to tensile deformation or Even in the case of compressive deformation, the deformability can be ensured and the occurrence of cracks can be suppressed, and as a result, the durability can be improved.

  As shown in FIG. 2, in the contact portion 120, the thickness dimension above the locking hole 121 (upper side in FIG. 2) is made larger than the thickness dimension of other portions. It is equal to or slightly larger than the distance between the opposing surfaces of the surface F and the locking hook F (see FIG. 1). As a result, the locking hook F is inserted into the locking hole 121, and the thick portion of the contact portion 120 is fitted between the opposing surfaces of the surface F and the locking hook F, thereby making the contact portion 120 the surface F. Can be adhered to. As a result, the cover member 1 can be firmly fixed to the surface F of the suspension member SM, and it is possible to suppress the entry of ice and snow from the gap between the contact portion 120 and the surface F.

  As shown in FIGS. 2 to 4, the contact portion 120 is provided with a pin hole 122 for inserting the engagement pin P (see FIG. 1). The pin hole 122 is a circular through hole, and has an inner diameter larger than the diameter of the engagement shaft of the engagement pin P and smaller than the diameter of the head of the engagement pin P. As a result, by engaging the engagement shaft portion of the engagement pin P inserted through the pin hole 122 with the suspension member SM, the contact portion 120 is held between the surface F and the head of the engagement pin P. As a result, the cover member 1 is held (mounted) on the suspension member SM.

  As shown in FIGS. 2 to 4, the connection wall 130 is a wall-like connection that connects the bottom surface (the front side surface in FIG. 4) of the separating portion 110 and the upper surface (the back side surface in FIG. 4) of the contact portion 120. It is a part, and is formed continuously along the outer edge of the bottom surface of the separation part 110 except for the part divided by the dividing path 112. The connection wall 130 includes a base 130a that is formed in a part of the wall that is continuously formed as described above.

  As shown in FIG. 2 to FIG. 4, the curved wall portion 130 a is a portion formed by being curved in a convex arc shape toward the separating portion 110 (insertion hole 111), and is an insertion hole adjacent to the slit portion 113. 111 is opposed to a corner portion (a corner portion adjacent to the slit 113 and positioned above the slit 113 in the weight direction when mounted on the vehicle, hereinafter referred to as a “corner portion 111a”). . Accordingly, the contact portion 120 in the vicinity of the corner portion 111a of the insertion hole 111 adjacent to the slit portion 113 can be prevented from floating from the surface F (see FIG. 1) of the suspension member SM. It is possible to prevent the intrusion of ice and snow by securing the adhesion between the two.

  That is, in the vicinity of the corner portion 111a of the insertion hole 111 adjacent to the slit portion 113, the degree of deformation when the first projecting piece 201 and the second projecting piece 202 are overlapped is large, and the excess thickness tends to concentrate. If the connecting wall 130 (curved wall portion 130a) facing the corner portion 111a of the hole 111 is curved in a convex arc shape toward the separating portion 110, the deformability of the curved wall portion 130a is secured. Thus, it is possible to suppress the occurrence of surplus. Further, the curved wall portion 130a is formed to be curved in a convex arc shape at a position facing the corner portion 111a of the insertion hole 111, so that the gap between the corner portion 111a of the insertion hole 111 and the curved wall portion 130a is formed. Since the distance (that is, the length of the separation portion 110) can be shortened, the deformability of the separation portion 110 in the vicinity of the corner portion 111a of the insertion hole 111 can be ensured, and the occurrence of excess wall can be suppressed. As a result, the contact portion 120 in the vicinity of the corner portion 111a of the insertion hole 111 adjacent to the slit portion 113 can be prevented from floating from the surface F (see FIG. 1) of the suspension member SM. It is possible to prevent the intrusion of ice and snow by securing the adhesion between the two.

  In the present embodiment, the formation range of the curved wall portion 130a is the same length as the extended length of the slit portion 113 (length in the left-right direction in FIG. 4). Further, the abutting portion 120 does not protrude outwardly in a flange shape at least within the formation range of the curved wall portion 130a, and the abutting portion 120 and the connection wall 130 (curved wall portion 130a) in the bottom view shown in FIG. ) Are formed in the same width dimension. In the present embodiment, a range in which the contact portion 120 and the connection wall 130 (curved wall portion 130a) are formed in the same width dimension also extends to one end side and the other end side of the curved wall portion 130a.

  That is, as shown in FIG. 3, the range on one end side extends to a position exceeding the center of one side (the upper side in FIG. 3) of the insertion hole 111 connected to the corner 111a, and the range on the other end side is a slit. The portion 113 extends to a position beyond the drilled end. In this manner, the contact portion 120 and the connection wall 130 (curved wall portion 130a) are formed to have the same width, so that the contact portion 120 and the connection wall 130 (curved wall portion) in the vicinity of the corner portion 111a of the insertion hole 111 are formed. It is possible to secure the deformability of 130a) and suppress the occurrence of surplus. As a result, the contact portion 120 in the vicinity of the corner portion 111a of the insertion hole 111 can be prevented from floating from the surface F (see FIG. 1) of the suspension member SM. It is possible to prevent the intrusion of ice and snow.

  Here, as shown in FIGS. 3 and 4, the separation portion 110 is a portion between the curved wall portion 130 a and the corner portion 111 a of the insertion hole 111 (at least a portion corresponding to the formation range of the curved wall portion 130 a). In addition, the rib portion 114 is not provided on the surface facing the surface F (see FIG. 1) of the suspension member SM (that is, a flat surface). Thereby, the deformability of the separation part 110 in the vicinity of the corner part 111a of the insertion hole 111 can be secured, and the occurrence of surplus can be suppressed. Therefore, since the contact portion 120 in the vicinity of the corner portion 111a of the insertion hole 110 can be prevented from floating from the surface F (see FIG. 1) of the suspension member SM, the adhesion between the contact portion 120 and the surface F is improved. It can be ensured and the intrusion of ice and snow can be suppressed.

  As shown in FIGS. 2 to 4, the first projecting piece 201 and the second projecting piece 202 are formed integrally with the main body part 100 (the separation part 110, the contact part 120, and the connection wall 130), and the main body part 100. 1 is a plate-like member that protrudes outward from the outer edge of the first member, and is provided with an engagement pin P (see FIG. 1) that can be engaged with the surface F of the suspension member SM. 201a and a second hole 202a.

  As shown in FIGS. 2 to 4, in the product state, the first projecting piece 201 and the second projecting piece 202 are located across the dividing path 112, and the first projecting piece 201 is located on the second projecting piece 202 side. It extends toward and overlaps with the extension region (the right region in FIG. 4) of the dividing path 112. Here, the positional relationship in the height direction of the first projecting piece 201 and the second projecting piece 202 will be described with reference to FIG.

  FIG. 5 is a cross-sectional view of the cover member 1 taken along the line VV in FIG. In FIG. 5, only the cross section is shown and other parts are partially omitted in order to simplify the drawing and facilitate understanding. As shown in FIG. 5, the first projecting piece 201 projects outward from the side surface (front side surface in FIG. 5) of the contact portion 120, and the bottom surface of the first projecting piece 201 (upper side surface in FIG. 5). ) Is formed flush with the bottom surface (upper side surface in FIG. 5) of the contact portion 120. On the other hand, the second projecting piece 202 protrudes outward from the side surface (front side surface in FIG. 5) of the connection wall 130, and contacts the bottom surface (upper side surface in FIG. 5) of the second projecting piece 202. The distance from the bottom surface is equal to the thickness dimension of the first protrusion 201 (the vertical dimension in FIG. 5).

  Therefore, the bottom surface (upper side surface in FIG. 5) of the second projection piece 202 is brought into contact with the upper surface (lower side surface in FIG. 5) of the first projection piece 201, so that the surface F (see FIG. 1) of the suspension member SM and the first. Without forming a gap between the bottom surface of the projecting piece 201 and between the upper surface of the first projecting piece 201 and the bottom surface of the second projecting piece 202, the first projecting piece 201 and the second projecting piece 202 are connected to each other. They can be superimposed (see FIG. 8).

In addition, when the 1st protrusion piece 201 and the 2nd protrusion piece 202 are piled up so that the hole position of the 1st hole 201a and the 2nd hole 202a may correspond, both the opposing sides of the dividing path 112 will adjoin. Is done. This state corresponds to the mounting state on the vehicle (see FIG. 6).
See). Here, the 1st hole 201a and the 2nd hole 202a are circular through-holes, and are comprised by the same diameter as the pin hole 122 mentioned above. Therefore, by overlapping the first protrusion 201 and the second protrusion 202 and engaging the engagement shaft portion of the engagement pin P inserted through the first hole 201a and the second hole 202a with the suspension member SM, The overlapped first projecting piece 201 and second projecting piece 202 are held between the surface F and the head of the engaging pin P. As a result, the cover member 1 is held (mounted) on the suspension member SM. The

  Next, a method for mounting the cover member 1 will be described with reference to FIGS. 6 and 7 are a rear view and a top view of the cover member 1, and FIG. 8 is a cross-sectional view of the cover member 1 taken along line VIII-VIII in FIG. 6 to 8, a state where the cover member 1 is mounted on the vehicle (mounted state) is virtually illustrated. Moreover, in FIG. 8, in order to simplify drawing and to make it easy to understand, only the cross section is shown and illustration of the other site | part is abbreviate | omitted partially.

  When the cover member 1 is mounted on the vehicle, first, the locking hole 121 is locked to the locking hook L (see FIG. 1) of the suspension member SM. As a result, the cover member 1 can be held on the suspension member SM while moving on the production line with the cover member 1 suspended from the suspension member SM.

  Next, the suspension member SM and the torque rod TR (see FIG. 1) are connected. In this case, the first projecting piece 201 and the second projecting piece 202 are displaced in a direction away from each other, the dividing path 112 is opened, and the rod R of the torque rod TR is inserted from the opened portion (dividing path 112). Fit into the hole 111.

  Finally, the engagement pin P is inserted into the pin hole 122, and the engagement shaft portion is engaged with the suspension member SM, so that the contact portion 120 is held by the suspension member SM. Further, FIGS. As shown in FIG. 1, the first projecting piece 201 and the second projecting piece 202 are overlapped, the engaging pin P is inserted into the first hole 201a and the second hole 202a whose hole positions are matched, and the engaging shaft portion thereof By engaging the suspension member SM with the suspension member SM, the superposed first protrusion piece 201 and second protrusion piece 202 are held by the suspension member SM. Thereby, the cover member 1 is attached to the suspension member SM (see FIG. 1).

  In this case, as shown in FIG. 6 and FIG. 7, since the separating portion 110 includes the slit portion 113, when the first projecting piece 201 and the second projecting piece 202 are overlapped by the space by the slit portion 113. Deformability can be secured and the occurrence of surplus can be suppressed. Therefore, since the contact portion 120 can be prevented from floating from the surface F of the suspension member SM, the adhesion between the contact portion 120 and the surface F can be secured, and the intrusion of ice and snow can be more reliably suppressed. Yes (see FIG. 1).

  As shown in FIGS. 6 and 7, the cover member 1 is formed in a trapezoidal shape when viewed from above in the mounted state, and the upper bottom side (upper side in FIG. 7) is locked by the locking hook F. The contact portion 120 is pressed (contacted) to the surface F, and the left and right ends on the lower bottom side (lower side in FIG. 7) are held between the head of the engagement pin P and the surface F (see FIG. 1), the contact portion 120 can be brought into close contact with the surface F while the number of the engagement pins P is reduced, and the formation of a gap can be suppressed.

  As described above, the cover member 1 has the first projecting piece 201 and the second projecting piece 202 overlapped with each other, and the first projecting piece P is inserted into the first projecting piece 201 by the one engaging pin P inserted into the first hole 201a and the second hole 202a. The two members 201 and the second projecting piece 202 can be held by the suspension member SM at a time. Therefore, compared with the case where a total of two engagement pins P are inserted into each of the first hole 201a of the first protrusion 201 and the second hole 202a of the second protrusion 202, the number of the engagement pins P The insertion work process can be reduced, and the parts cost and work cost can be reduced accordingly.

  In the case where the main body 100 is formed in a single plate shape, when the main body 100 is deformed by being pressed by the swinging torque rod TR, a part of the main body 100 is caused to be suspended by the suspension member SM. As a result of floating from the surface F and forming a gap, it becomes easy for ice and snow to invade. On the other hand, by connecting the separation portion 110 and the contact portion 120 with the connection wall 130 so as to change the positional relationship between the separation portion 110 and the contact portion 120, the torque rod TR can be changed. In the case of rocking, the rocking is absorbed by the deformation of the separating portion 110 and the connecting wall 130, and the contact portion 120 can be prevented from floating from the surface F of the suspension member SM. As a result, the adhesion between the contact portion 120 and the surface F can be ensured, and the intrusion of ice and snow can be more reliably suppressed.

  Further, since the separating portion 120 includes the slit portion 113, the separating portion 110 itself can be easily deformed. Therefore, when the torque rod TR swings, the swing is mainly deformed. It is possible to suppress the contact portion 120 from floating from the surface F of the suspension member SM. As a result, the adhesion between the contact portion 120 and the surface F can be ensured, and the intrusion of ice and snow can be more reliably suppressed.
