  However, according to the prior art described in Patent Document 1, it is impossible to achieve both the workability of attaching the pipe to the pipe penetrating part and the sealability between the pipe and the pipe penetrating part.

  More specifically, in the pipe support structure disclosed in Patent Document 1, an annular protrusion (spool portion) is formed on the pipe. Moreover, the pipe penetration part is formed so that it may become a uniform shape in the circumferential direction of the pipe when the pipe is inserted through the pipe penetration part. For this reason, when inserting the pipe through the pipe penetration part, the entire annular protrusion is brought into contact with the pipe insertion part, and a large pushing force is applied to the pipe until the entire pipe insertion part is deformed to a size capable of inserting the annular protrusion. It is necessary to push it into the pipe insertion part. Therefore, in the pipe support structure disclosed in Patent Document 1, it is not possible to ensure the workability of attaching the pipe to the pipe penetration portion.

  In addition, it is possible to reduce the pushing force applied to the pipe by providing a notch in the pipe penetrating part and to secure the workability of attaching the pipe to the pipe penetrating part. The sealability cannot be ensured.

  In consideration of the above facts, the present invention can provide a seal member capable of achieving both mounting workability of the piping member to the sealing member and sealing performance of the piping member and the sealing member, and a piping seal structure including the sealing member. Is the purpose.

  The seal member according to the first aspect of the present invention has elasticity, an outer peripheral seal portion that is brought into contact with a peripheral portion of an insertion hole for inserting a piping member formed in the vehicle body component member in a surface contact state, and elastic The outer peripheral seal portion is provided integrally with the outer peripheral seal portion so as to cover the insertion hole with the outer peripheral seal portion, and the outer peripheral seal portion side is opened so that the piping member can be inserted. An insertion part configured to include a lid part in which a fitting insertion hole into which a pipe part constituting the piping member can be fitted is formed, and a part of a peripheral edge of the fitting insertion hole, and the lid When the pipe portion is inserted into the fitting insertion hole from the insertion hole side, the outer circumferential portion of the pipe portion is inclined toward the lid portion from the outer circumference side of the fitting portion toward the center side of the fitting insertion hole.

  Then, the spool portion starts to be partially inserted from the portion where the inclined portion is provided in the peripheral edge portion of the fitting insertion hole, and the spool portion is fitted and inserted so that the fitting insertion hole is not large enough to be inserted into the spool portion. It is inserted through the hole. As a result, the pushing force applied to the piping member when the piping member is inserted through the fitting insertion hole can be reduced.

  The sealing member according to a second aspect of the present invention is the sealing member according to the first aspect, wherein the inclination angle of the inclined portion gradually increases as it approaches a predetermined position in the peripheral edge portion of the fitting insertion hole. , It gradually decreases as the distance from the location is exceeded.

  According to the second aspect of the present invention, when the pipe portion is inserted into the insertion insertion hole from the insertion hole side, the spool portion starts to be inserted from a location where the inclination portion has the largest inclination angle. The spool portion is inserted from a portion where the inclination angle is smaller than that of the portion. For this reason, when a piping member is penetrated by a fitting insertion hole, it can suppress that the pushing force concerning the peripheral part of the said fitting insertion hole changes rapidly.

  Here, the present embodiment is characterized in that an inclined portion 72 is formed in the insertion portion 50 as shown in FIG. Hereinafter, the structure of the inclined part 72 which is the principal part of this invention is demonstrated in detail.

  As an example, the inclined portion 72 is formed in a part of the peripheral edge portion of the fitting insertion hole 56 formed in the lid portion 52 that constitutes the insertion portion 50, and this is the same as the cylindrical portion 54 that constitutes the insertion portion 50. It can also be understood that a part is the inclined portion 72. When the insertion portion 50 is viewed as a whole, the inclined portion 72 is formed on the insertion portion 50 in the insertion direction side of the breather pipe 28 and the opposite insertion direction side of the breather pipe 28 in the insertion portion 50 is opened. It has become.

  Further, the inclined portion 72 is 90 degrees to 270 degrees with the direction of the center line CL of the lid portion 52 extending from the center of the fitting insertion hole 56 to the outer peripheral seal section 42 as viewed from the axial direction of the fitting insertion hole 56 as 0 degrees.

The shape is set so as to be in contact with each other.

(Operation and effect of this embodiment)
Next, the operation and effect of this embodiment will be described.

  In the present embodiment, as shown in FIG. 1, the outer peripheral seal portion 42 constituting the seal members 40, 58 is inserted into the insertion hole 24 for inserting the breather pipe 28 formed in the side wall portions 14, 16 of the floor member 12. It is contact | abutted to the peripheral part of 26 in the surface contact state. In addition, the outer peripheral seal portion 42 has elasticity, and the outer peripheral seal portion 42 and the peripheral portions of the insertion holes 24 and 26 are in close contact with each other.

  By the way, if the annular spool portion 32 is formed in the breather pipe 28, it is difficult to ensure the workability of attaching the breather pipe 28. More specifically, the breather pipe 28 is inserted through the fitting insertion hole 56 of the insertion portion 50 in the work of attaching the breather pipe 28. At this time, the spool portion 32 is brought into contact with the lid portion 52 of the insertion portion 50, and a large pressing force is applied to the breather pipe 28 until the insertion insertion hole 56 has a size that allows the spool portion 32 to be inserted. 56 need to be pushed into.

  Here, in the present embodiment, an inclined portion 72 is formed in a part of the peripheral edge portion of the fitting insertion hole 56, and the inclined portion 72 is directed from the outer peripheral side of the lid portion 52 toward the center side of the fitting insertion hole 56. And incline toward the lid portion 52. The inclined portion 72 is in contact with the annular spool portion 32 formed integrally with the outer peripheral portion of the pipe portion 30 when the pipe portion 30 is inserted into the insertion hole 56 from the insertion holes 24 and 26 side. It has become so.

  Therefore, when the pipe portion 30 is inserted into the insertion hole 56, the spool portion 32 is brought into contact with the inclined portion 72, and the inclined portion 72 is pressed by the spool portion 32, so that the periphery of the insertion insertion hole 56 is A portion where the inclined portion 72 is provided is locally expanded. Hereinafter, the process in which the breather pipe 28 is inserted through the fitting hole 56 will be described with reference to FIG. FIG. 2 shows a process in which the breather pipe 28 is inserted into the fitting insertion hole 56 of the seal member 40.

  First, as shown in FIG. 2A, in the first process, the end portion 28A of the breather pipe 28 is inserted into the insertion portion 50, and the other end portion 30A of the pipe portion 30 is inserted into the fitting insertion hole 56. Inserted. The breather pipe 28 is pushed in until the spool portion 32 comes into contact with the inclined portion 72.

  Next, as shown in FIG. 2B, in the second process, the inclined portion 72 pressed by the spool portion 32 is elastically deformed so as to extend in a direction along the insertion direction of the breather pipe 28. In this state, the portion of the lid portion 52 adjacent to the inclined portion 72 is inclined toward the insertion direction of the breather pipe 28, in other words, the portion is in a state of functioning as the inclined portion 74. .

  Next, as shown in FIG. 2 (C), in the third process, the breather pipe 28 is pushed in, and the inclined portion 74 is pressed by the spool portion 32, so that the spool is inserted from the inclined portion 74 side of the fitting hole 56. Part 32 begins to be partially inserted.

  2D, in the fourth process, the breather pipe 28 is pushed in until the end portion 28A of the breather pipe 28 inserted through the fitting insertion hole 56 reaches the quick connector 34. .

  Thus, in the present embodiment, the spool portion 32 is inserted into the fitting insertion hole 56 without the fitting insertion hole 56 having such a size that the spool portion 32 can be inserted therethrough. For this reason, the pushing force applied to the breather pipe 28 when the breather pipe 28 is inserted into the fitting insertion hole 56 can be reduced. As a result, both the workability of attaching the breather pipe 28 to the seal members 40 and 58 and the sealability of the breather pipe 28 and the seal members 40 and 58 can be achieved.

  Moreover, the insertion holes 24 and 26 are formed in the floor member 12 which is a vehicle body constituting member, and the breather pipe 28 is inserted into the insertion holes 24 and 26, so that the breather can be disposed even on the lower side of the vehicle body floor. Can be arranged without interfering with the vehicle body. As a result, it is possible to contribute to lowering the floor structure of the vehicle body structure.

  Further, in the present embodiment, the inclination angle α of the inclined portion 72 gradually increases as it approaches the position farthest from the outer peripheral seal portion 42 at the peripheral edge of the fitting insertion hole 56, and exceeds the position from the position. It gets smaller gradually as you leave. For this reason, when the pipe part 30 is inserted in the insertion hole 56 from the insertion holes 24 and 26 side, the spool part 32 starts to be inserted from a position where the inclination angle α of the inclination part 72 is the largest. Subsequently, the spool portion is inserted from a portion having a smaller inclination angle α than a portion having the largest inclination angle α in the inclined portion 72.

  Thus, in this embodiment, when the breather pipe 28 is inserted through the fitting insertion hole 56, it is possible to suppress a sudden change in the pushing force applied to the peripheral edge of the fitting insertion hole 56. As a result, it is possible to prevent stress concentration from occurring in the seal members 40 and 58 during the work of attaching the breather pipe 28.
