Title: Cushion clip

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a cushion clip. More particularly, the present invention relates to a cushion clip that is attached to one (i.e., an attachment member) of two members capable of relatively moving toward each other in order to dampen collision between the two members and to absorb impact from the other of the two members. 
     2. Description of Related Art 
     A known cushion clip of this type is taught by, for example, Japanese Patent Number 3401242. As shown in  FIG. 10 , a cushion clip  101  is attached to a door frame F 2  (an attachment member) of a vehicle, so as to dampen collision between the door frame F 2  and a door D 2  (an associated member) when the door D 2  is closed. The cushion clip  101  may be integrally formed. The cushion clip  101  may include an engagement portion  110  that is capable of being inserted into an attachment hole H 2  formed in the door frame F 2 , and a cushioning portion  120  that is configured to be projected from the door frame F 2  to receive and absorb shock from the door D 2 . The engagement portion  110  is made of a hard resinous material having rigidity such as polypropylene. Conversely, the cushioning portion  120  is made of an elastomeric resinous material having elasticity such as silicon rubber. Thus, in the cushion clip  101 , the cushioning portion  120  can elastically absorb the impact that can be produced when the door D 2  is closed. 
     However, in the known cushion clip  101 , when the cushion clip  101  is pressed by the door D 2  due to vibration caused by traveling of the vehicle, the engagement portion  110  made of the hard resinous material can contact the door frame F 2 , thereby generating noise. Thus, there is a need in the art for an improved cushion clip. 
     BRIEF SUMMARY OF THE INVENTION 
     For example, one aspect of the present invention may provide a cushion clip that is configured to be attached to a first member of two members capable of relatively moving toward each other in order to dampen collision between the two members, which may include a support portion made of a hard material and capable of being connected to an attachment hole formed in the first member, and a cushioning portion made of a soft material and integrally connected to the support member by two-color molding. The support portion is integrally formed and has an engagement portion that is configured to be inserted into and engaged with the attachment hole, and a head portion to which the cushioning portion is integrally connected by two-color molding. The head portion has a shoulder surface that is formed in a columnar portion thereof. The shoulder surface is directed in an insertion direction of the support portion into the attachment hole. The cushioning portion is configured to project from the first member when the support portion is connected to the attachment hole, so as to elastically absorb impact from a second member. The cushioning portion has a base portion that is positioned to surround the columnar portion of the head portion. The base portion of the cushioning portion has a bulged portion that is formed in at least a portion thereof so as to extend along the columnar portion. The bulged portion is shaped to project beyond the shoulder surface in the insertion direction of the support portion, so as to elastically contact the first member when the cushion clip is applied with the impact from the second member. 
     According to the aspect of the invention, when the cushion clip is applied with the impact from the second member, the cushioning portion is capable of elastically receiving and absorbing the impact. At this time, the bulged portion of the cushioning portion may elastically contact the first member while the support portion cannot contact the first member. As a result, production of noise can be eliminated. 
     Optionally, the head portion may include an enlarged portion. The enlarged portion of the head portion may be configured to support the base portion of the cushioning portion when the impact is applied to the cushion clip from the second member, so as to prevent the base portion from excessively deforming in a direction opposite to the insertion direction of the support portion. 
     Other objects, features and advantages of the present invention will be readily understood after reading the following detailed description together with the accompanying drawings and the claims.

     DETAILED DESCRIPTION OF THE INVENTION 
     Next, a representative embodiment of the present invention will be described with reference to  FIGS. 1 to 9 . 
     As shown in  FIGS. 1 and 7 , a representative cushion clip  1  may be configured to be attached to a back door D (a first or attachment member) of a vehicle (not shown), so as to dampen collision between the door D and a body panel F 1  (a second or associated member) when the door D is closed and to absorb impact produced therebetween. The cushion clip  1  may preferably be integrally formed. The cushion clip  1  may include a support (hard) portion  10  that is constructed to be connected to an (circular) attachment hole H 1  formed in a door panel D 1  of the door D, and a cushioning portion  20  that is constructed to be projected from the door panel D 1  to elastically receive and absorb the impact produced between the door D and the body panel F 1  when the door D is closed. 
     The support portion  10  may preferably be made of a hard resinous material having rigidity such as polypropylene, so as to have rigidity. In particular, as shown in  FIG. 3 , the support portion  10  may preferably have an (lower) engagement portion  12  and a (upper) head portion  11 . The engagement portion  12  may be configured to be inserted into and engaged with the attachment hole H 1 . That is, the engagement portion  12  may have a diameter smaller than the diameter of the attachment hole H 1 , so as to be introduced thereinto. The head portion  11  may be constructed such that the cushioning portion  20  can be integrally connected thereto by two-color molding. Further, the support portion  10  thus formed may have sufficient rigidity because it is made of the hard resinous material. Therefore, the engagement portion  12  can be smoothly inserted into the attachment hole H 1  of the door panel D 1  in order to connect the support portion  10  thereto. 
     As shown in  FIGS. 1 ,  3  and  4 , the head portion  11  may preferably have a (lower) columnar portion  11 B continuous with the engagement portion  12  and an (upper) enlarged portion  11 C continuous with the columnar portion  11 B. The columnar portion  11 B has a diameter greater than a diameter of the engagement portion  12 . Further, the head portion  11  may have an annular shoulder surface  11 A (an annular sealing surface) that is formed in the columnar portion  11 B. The shoulder surface  11 A may preferably be directed in an insertion direction P of the support portion  10  into the attachment hole H 1  (downward in  FIGS. 1 ,  3  and  4 ), which direction may be referred to as an axially forward direction P of the support portion  10 . Therefore, the shoulder surface  11 A may be positioned opposite to the door panel D 1  when the cushion clip  1  is attached to the back door D (the door panel D 1 ). 
     Conversely, the cushioning portion  20  is made of a soft resinous material having elasticity such as a thermoplastic elastomer, so as to have elastic deformability. The cushioning portion  20  may preferably be integrally connected to the head portion  11  of the support portion  10  by two-color molding while the head portion  11  is embedded in the cushioning portion  20 . As shown in  FIGS. 3 and 4 , the cushioning portion  20  thus formed may have a substantially cylindrical (lower) base portion  21  surrounding the columnar portion  11 B of the support portion  10  and a substantially truncated cone-shaped or frustconical (upper) main body portion  22  continuous with the base portion  21 . Further, the cushioning portion  20  may have an end surface  22 A (an upper end surface in  FIGS. 3 and 4 ) that is formed in the main body portion  22 . As best shown in  FIG. 2 , the base portion  21  may preferably have a bulged portion  21 A that is circumferentially formed in a flattened bottom surface of the based portion  21 , and an annular lip portion  21 B that is circumferentially formed in a periphery of the bottom surface. As best shown in  FIG. 5 , the bulged portion  21 A may be formed in a portion of the base portion  21 , so as to extend along the columnar portion  11 B (the shoulder surface  11 A) of the support portion  10  with an annular spacing surface  21 C therebetween. The bulged portion  21 A may preferably be shaped to axially uniformly project (upward in  FIG. 2 ) beyond the shoulder surface  11 A in the insertion direction P of the support portion  10 . Further, the bulged portion  21 A may preferably have a pair of removed portions  21 A 1  that are positioned diametrically opposite to each other. As a result, the bulged portion  21 A is substantially composed of a pair of substantially semicircular portions. Conversely, the lip portion  21 B may preferably be formed to circumferentially surround the bulged portion  21 A. Further, the bottom surface (the spacing surface  21 C) of the based portion  21  may preferably be formed to be flush with the shoulder surface  11 A of the support portion  10 . 
     As shown in  FIG. 7 , when the cushion clip  1  attached to the door D is applied with the impact from the body panel F 1 , the cushioning portion  20  may be compressed in the insertion direction P thereof (downward in  FIG. 7 ). Thus, an elastic force may be produced therein, so that the impact from the body panel F 1  can be absorbed. In particular, when the body panel F 1  relatively moves toward and contact the cushion clip  1  attached to the door D, the body panel F 1  may be received by the main body portion  22  of the cushioning portion  20 . As a result, the cushioning portion  20  may be elastically deformed, so that the impact from the body panel F 1  can be absorbed thereby. At this time, the support portion  10  may be applied with a pressing force that presses the same into the attachment hole H 1 . Simultaneously, the bulged portion  21 A may fully elastically contact the door panel D 1 . Thus, the support portion  10  (the shoulder surface  11 A) may effectively be prevented from contacting the door panel D 1 . 
     In the cushion clip  1  of the present embodiment, the shoulder surface  11 A of the support portion  10  is positioned opposite to the door panel D 1 . Therefore, when the support portion  10  (the engagement portion  12 ) moves toward the attachment hole H 1 , the shoulder surface  11 A may contact the door panel D 1  to produce noise unless the bulged portion  21 A is formed in the cushioning portion  20 . However, as described above, because the cushioning portion  20  has the bulged portion  21 A, when the cushion clip  1  is applied with the impact from the body panel F 1  (the door panel D 1 ), the bulged portion  21 A of the cushioning portion  20  may fully elastically contact the door panel D 1 . As a result, the shoulder surface  11 A of the support portion  10  may be prevented from contacting the door panel D 1 , so that production of the noise can be eliminated. 
     As previously described, the head portion  11  of the support portion  10  may have the enlarged portion  11 C. As shown in  FIGS. 3 to 5 , the enlarged portion  11 C of the head portion  11  is radially enlarged, i.e., extended outwardly beyond the columnar portion  11 B (the shoulder surface  11 A). The enlarged portion  11 C may support the base portion  21  of the cushioning portion  20  in the insertion direction P of the support portion  10  (from above in the drawings) when the impact from the body panel F 1  is applied to the cushion clip  1 , so as to prevent the base portion  21  from excessively deforming in a direction opposite to the insertion direction P of the support portion  10 . Thus, the enlarged portion  11 C of the head portion  11  may have increased support performance for supporting the base portion  21 . As a result, the bulged portion  21 A formed in the base portion  21  may reliably elastically contact the door panel D 1  when the impact is applied to the cushion clip  1 , so that the shoulder surface  11 A of the support portion  10  may be reliably prevented from contacting the door panel D 1 . Therefore, the production of the noise can be reliably eliminated. 
     As shown in  FIGS. 1 and 6 , the enlarged portion  11 C of the head portion  11  has a plurality of depressed portions circumferentially formed therein, so as to form a plurality of (eight in this embodiment) ribs  11 C 1  therearound. Therefore, the head portion  11  (the enlarged portion  11 C) may be reliably connected to or integrated with the cushioning portion  20 , so as to have an increased connecting strength to the cushioning portion  20 . As a result, the support performance of the enlarged portion  11 C for supporting the base portion  21  can be further increased. 
     As shown in  FIGS. 1 ,  3  and  4 , the columnar portion  11 B of the head portion  11  may have a diameter greater than a diameter of the attachment hole H 1 . Further, the columnar portion  11 B may be formed to have a substantially uniform diameter over the entire length thereof. As shown in  FIGS. 3 and 4 , a lower end periphery of the columnar portion  11 B (i.e., an end periphery of the columnar portion  11 B in the insertion direction P of the support portion  10 ) may be circumferentially removed, thereby forming a thinned portion  11 B 1  therein. The thinned portion  11 B 1  may be shaped to have a diameter smaller than the diameter of the attachment hole H 1 , so as to be introduced thereinto. Further, when the end periphery of the columnar portion  11 B is circumferentially removed to form the thinned portion  11 B 1 , the shoulder surface  11 A of the head portion  11  may be simultaneously formed in the columnar portion  11 B. Therefore, the shoulder surface  11 A may have the same outer diameter as the diameter of the columnar portion  11 B, which diameter is greater than the diameter of the attachment hole H 1 , and may have the same inner diameter as the diameter of the thinned portion  11 B 1 , which diameter is smaller than the diameter of the attachment hole H 1 . Further, the shoulder surface  11 A may preferably be shaped to have a flattened surface. 
     As shown in  FIGS. 1 to 5 , the engagement portion  12  may be extended from the head portion  11  (the columnar portion  11 B) in the insertion direction P of the support portion  10  and may have a substantially columnar shape that is capable of being inserted into the annular attachment hole H 1  formed in the door panel D 1  of the door D. Further, the engagement portion  12  may have a pair of engagement strips  12 A that are formed in an outer circumferential surface thereof. The engagement strips  12 A may be diametrically oppositely positioned and may be constructed to be diametrically flexed relative to each other. Further, the engagement strips  12 A may preferably be positioned to be diametrically aligned with the removed portions  21 A 1  formed in the base portion  21  of the cushioning portion  20 . In addition, the engagement portion  12  may preferably have a pair of open ended hollow portions  12 B that are formed therein. The hollow portions  12 B may be formed to extend in a longitudinal direction of the engagement portion  12 . The hollow portions  12 B may preferably extend into the head portion  11 , so as to continuously form bottomed hollow portions therein. 
     Further, as best shown in  FIG. 5 , the hollow portions  12 B may preferably be diametrically aligned with the engagement strips  12 A, so that the engagement strips  12 A can be easily flexed. As will be appreciated, when the engagement portion  12  is pushed into the attachment hole H 1  formed in the door panel D 1  of the door D, the engagement portion  12  may be introduced into the attachment hole H 1  while the engagement strips  12 A are diametrically contracted by an inner circumference of the attachment hole H 1 . After the engagement portion  12  is substantially introduced into the attachment hole H 1 , the engagement strips  12 A may be restored or expanded to elastically engage the inner circumference of the attachment hole H 1 , so that the engagement portion  12  can be connected to the attachment hole H 1 . Further, as shown in  FIG. 3 , each of the engagement strips  12 A may have an inclined engagement surface  12 A 1 , so as to reliably engage the inner circumference of the attachment hole H 1  even when a thickness of the door panel D 1  is changed. 
     As shown in  FIGS. 1 and 3 , the substantially frustconical (upper) main body portion  22  of the cushioning portion  20  may be formed so as to be extended from the base portion  21  in the direction opposite to the insertion direction P of the support portion  10  when the cushion clip  1  is attached to the door panel D 1 . As shown in  FIGS. 3 ,  4  and  6 , the main body portion  22  may preferably have a bottomed cylindrical hollow portion  22 B that is formed therein. The hollow portion  22 B may be formed to extend in a longitudinal direction of the main body portion  22 . The hollow portion  22 B may preferably be opened in the end surface  22 A of the main body portion  22  (the cushioning portion  20 ). Further, as best shown in  FIG. 6 , the main body portion  22  may preferably have a plurality (four in this embodiment) of ribs  22 C. The ribs  22 C are radially formed in the end surface  22 A of the main body portion  22  while being partially hanged over a circumferential surface of the main body portion  22 . 
     As will be recognized, the bottomed hollow portion  22 B formed in the main body portion  22  may function to change elastic deformability or elastic force of the main body portion  22 . Therefore, it is possible to change the elastic force of the main body portion  22  by changing a size of the hollow portion  22 B. Conversely, as shown in  FIG. 3 , each of the ribs  22 C of the main body portion  22  may preferably have a height W 2 . Therefore, when the body panel F 1  collides the cushion clip  1  attached to the door D, the ribs  22 C may contact the body panel F 1  before the end surface  22 A of the main body portion  22  contacts the body panel F 1 , so that the main body portion  22  can gently absorb the impact. 
     As shown in  FIGS. 3 and 4 , the cushion clip  1  is arranged and constructed such that the main body portion  22  cannot contact the body panel F 1  when a relation between the door D and the body panel F 1  is in a normal condition, i.e., when the door D is being closed. In particular, the cushion clip  1  is arranged and constructed such that the end surface  22 A of the main body portion  22  can be positioned opposite to the body panel F 1  with a clearance W 1  that is greater than the height W 2  of each of the ribs  22 C when the door D is being closed. Thus, in the normal condition, the cushion clip  1  (the main body portion  22 ) can be prevented from being pressed by the body panel F 1 . 
     The bulged portion  21 A of the base portion  21  may preferably be shaped to have a flattened surface. Thus, when the impact from the body panel F 1  is applied to the cushion clip  1  attached to the door D, the bulged portion  21 A can reliably contact the door panel D 1 , so as to produce the elastic force that is capable of effectively absorb the impact. 
     As best shown in  FIG. 1 , the lip portion  21 B of the base portion  21  may preferably be formed in the periphery of the bottom surface of the base portion  21 , so as to be flared in the insertion direction P of the support portion  10  (downwardly in  FIG. 1 ). As shown in  FIGS. 3 and 4 , the lip portion  21 B thus shaped may be elastically flexed to closely contact a surface of the door panel D 1  of the door D when the engagement portion  12  of the support portion  10  is inserted into the attachment hole H 1  formed in the door panel D 1 , so as to prevent rainwater, dust or other such materials from entering the door D through the attaching hole H 1 . 
     A representative method for manufacturing the cushion clip  1  will now be described with reference to  FIGS. 2 to 10 . In this embodiment, the cushion clip  1  may preferably be manufacture by two-color molding. That is, the support portion  10  may be formed (a primary molding process). Thereafter, the cushioning portion  20  may be integrally formed on the support portion  10  (a secondary molding process), thereby producing the cushion clip  1 . 
     First, as shown in  FIG. 8 , a first upper die element M 1  (a primary molding die element) may be disposed on a lower die element M 3  (a common molding die element), so as to from a first molding cavity C 1  between a molding surface S 1  of the first upper die element M 1  and a first molding surface S 2  of the lower die element M 3  (a primary die closing step). Thereafter, a first molding material P 1  (i.e., the hard resinous material such as polypropylene) may be fed into the first molding cavity C 1 , thereby forming the support portion  10  (a primary molding step). After the primary molding step is completed, the first upper die element M 1  may be removed from the lower die element M 3  (a primary die-opening step). 
     Subsequently, as shown in  FIG. 9 , a second upper die element M 2  (a secondary molding die element) may be disposed on the lower die element M 3  with leaving the formed support portion  10  on the lower die element M 3 , so as to from a second molding cavity C 2  among a molding surface S 3  of the second upper die element M 2 , a second molding surface S 4  of the lower die element M 3  and an outer surface S 5  of the support portion  10  (a secondary die closing step). Thereafter, a second molding material P 2  (i.e., the soft resinous material such as the thermoplastic elastomer) may be fed into the second molding cavity C 2 , thereby integrally forming the cushioning portion  20  on the head portion  11  of the support portion  10  (a secondary molding step). Thus, the cushion clip  1  may be formed. After the secondary molding step is completed, the second upper die element M 2  may be removed from the lower die element M 3  (a secondary die-opening step), so that the cushion clip  1  can be removed from the lower die element M 3 . 
     The first upper die element M 1  may preferably be composed of a plurality of slide die parts (not shown) that are capable of radially moving or sliding. Therefore, in the primary die-opening step, the first upper die element M 1  can be easily removed from the support portion  10  (the head portion  11 ) although the head portion  11  has an undercut (e.g., the enlarged portion  11 C). Similarly, the lower die element M 3  may preferably be composed of a plurality of slide die parts (not shown) that are capable of radially moving or sliding. Therefore, in the secondary die-opening step, the lower die element M 3  can be easily released from the support portion  10  (the engagement portion  12 ) although the engagement portion  12  has an undercut (e.g., the engagement strips  12 A). 
     Further, the support portion  10  formed in the first molding cavity C 1  may be shrunk with time, so as to be reduced in size. That is, as shown in  FIG. 9 , a clearance M 3 A may be formed between the first molding surface S 2  of the lower die element M 3  and the outer surface S 5  of the support portion  10  by shrinking of the support portion  10 . Therefore, the molding surface S 1  of the first upper die element M 1  and the first molding surface S 2  of the lower die element M 3  may preferably be shaped such that the first molding cavity C 1  formed therebetween can have a size greater than a predetermined size of the support portion  10  in consideration of a shrinkage of the support portion  10 . 
     As shown in  FIG. 8 , in the primary molding step, the head portion  11  of the support portion  10  may be molded only by the molding surface S 1  of the first upper die element M 1  while the engagement portion  12  of the support portion  10  may be molded only by the first molding surface S 2  of the lower die element M 3 . As a result, when the first upper die element M 1  is removed from the lower die element M 3 , the support portion  10  can be left on the lower die element M 3  while only the head portion  11  thereof is projected from the lower die element M 3 . Therefore, in the secondary molding step, the cushioning portion  20  can be integrally molded on the support portion  10  while only the head portion  11  is embedded therein. 
     As shown in  FIG. 8 , in the primary molding step, the shoulder surface  11 A of the head portion  11  may be formed by an annular flat molding surface M 3 B formed in the lower die element M 3 . Conversely, as shown in  FIG. 9 , in the secondary molding step, the annular molding surface M 3 B may function to form the annular spacing surface  21 C of the based portion  21  of the cushioning portion  20 . Therefore, the annular molding surface M 3 B may have a width greater than a width of the shoulder surface  11 A of the head portion  11 . As a result, in the primary molding step, the annular molding surface M 3 B may function as a sealing surface between the first upper die element M 1  and the lower die element M 3 , so that the first molding material P 1  can be prevented from being leaked out of the first molding cavity C 1 . 
     To the contrary, as shown in  FIG. 9 , in the secondary molding step, the annular molding surface M 3 B may function as a sealing surface between the support portion  10  and the lower die element M 3 . That is, the annular molding surface M 3 B may closely contact the shoulder surface  11 A of the head portion  11 , so that the second molding cavity C 2  can be separated from the clearance M 3 A formed between the lower die element M 3  and the support portion  10 . Therefore, the second molding material P 2  can be prevented from being leaked out of the second molding cavity C 2  and entering the clearance M 3 A formed in the lower die element M 3 . Further, the annular molding surface M 3 B may contact the shoulder surface  11 A of the head portion  11  by plane contact, so that the second molding cavity C 2  can be reliably separated from the clearance M 3 A even when the support portion  10  is shrunk. 
     Next, a method of using the cushion clip  1  will now be described. 
     First, as shown in  FIG. 1 , in order to attach the cushion clip  1  to the door panel D 1  of the door D, the engagement portion  12  of the support portion  10  may be pushed into the attachment hole H 1  formed in the door panel D 1 . As a result, the engagement portion  12  may be inserted into the attachment hole H 1  while the engagement strips  12 A are diametrically inwardly contracted by the inner circumference of the attachment hole H 1 . As shown in  FIGS. 3 and 4 , upon insertion of the engagement portion  12 , the engagement strips  12 A may be restored or expanded to elastically engage the inner circumference of the attachment hole H 1 , so that the engagement portion  12  (the support portion  10 ) can be connected to the attachment hole H 1 . Thus, the cushion clip  1  can be attached to the door panel D 1 . 
     At this time, as shown in  FIGS. 3 and 4 , the lip portion  21 B of the cushioning portion  20  (the base portion  21 ) can be elastically flexed to closely contact the surface of the door panel D 1  while the bulged portion  21 A of the cushioning portion  20  is positioned opposite to the surface of the door panel D 1  with a space. 
     According to the cushion clip  1  of the present invention, as shown in  FIG. 7 , when the cushion clip  1  attached to the door panel D 1  is applied with the impact from the body panel F 1 , the cushioning portion  20  can be compressed axially. At this time, the bulged portion  21 A of the cushioning portion  20  may fully elastically contact the door panel D 1 , so as to prevent the shoulder surface  11 A of the support portion  10  from contacting the door panel D 1 . As a result, production of the noise can be eliminated. 
     Further, when the impact is applied to the cushion clip  1  from the body panel F 1 , the ribs  22 C formed in the main body portion  22  of the cushioning portion  20  may contact the body panel F 1  before the end surface  22 A of the main body portion  22  contacts the body panel F 1 , so that the impact can be gently absorbed by the main body portion  22 . 
     Naturally, various changes and modifications may be made to the present invention without departing from the scope of the invention. For example, an engagement structure of the engagement portion  12  of the support portion  10  and the attachment hole H 1  can be changed as necessary. Further, the enlarged portion  11 C of the support portion  10  (the head portion  11 ) can be modified in shape and size. For example, the ribs  11 C 1  formed in the enlarged portion  11 C can be omitted. Further, the enlarged portion  11 C can have circumferentially discontinuous portions that are formed therein. In addition, the enlarged portion  11 C can be omitted as necessary. Further, the shoulder surface  11 A of the head portion  11  can be shaped to be inclined. 
     Further, in the embodiment, polypropylene is exemplified as the hard resinous material. However, the hard resinous material may include polyacetal (e.g., polyoxymethylene (POM)), nylon, polybutyleneterephthalate, polyethylene and PC/ABS alloys. That is, the support portion  10  can be made of various materials having suitable rigidity provided that they are suitable for the primary molding process in the two-color molding. 
     Further, in the embodiment, the thermoplastic elastomer is exemplified as the soft resinous material. However, the soft resinous material may include polyvinyl chloride, silicon rubber and rubber. That is, the cushioning portion  20  can be made of various materials having suitable elasticity provided that they are suitable for the secondary molding process in the two-color molding. 
     Further, a construction of the main body portion  22  of the cushioning portion  20  can be changed as necessary. Further, the annular lip portion  21 B of the cushioning portion  20  (the base portion  21 ) can be modified in shape and size. Further, the annular lip portion  21 B can be omitted as necessary. 
     In this embodiment, the bulged portion  21 A of the cushioning portion  20  is formed as a pair of substantially semicircular portions that extend along the shoulder surface  11 A (the columnar portion  11 B) of the support portion  10  and that uniformly project from the bottom surface of the based portion  21  beyond the shoulder surface  11 A. However, the bulged portion  21 A can be formed as a plurality of projections that are discontinuously formed in the base portion  21  to be positioned along the shoulder surface  11 A. Also, the bulged portion  21 A can be formed as an annular projection that is continuously formed in the base portion  21  to be positioned along the shoulder surface  11 A. That is, the removed portions  21 A 1  formed in the bulged portion  21 A can be omitted. Further, the bulged portion  21 A can be formed in the base portion  21  such that the spacing surface  21 C cannot be formed between the bulged portion  21 A and the shoulder surface  11 A. 
     In this embodiment, as shown in  FIGS. 1 and 7 , the cushion clip  1  is attached to the door panel D 1  (a movable member) of the back door D of the vehicle, so as to dampen the collision between the door panel D 1  and the body panel F 1  (a stationary member) when the door D is closed or when vibration caused by traveling of the vehicle is generated. However, the present invention can be applied to a cushion clip that is attached to one of various types of two members capable of relatively moving toward each other in order to dampen the collision therebetween. A door and a door frame of a vehicle can be exemplified as the two members. Further, the cushion clip can be attached to either of the two members.
