The front configuration of the outer seal member 50 and the leveling member 60 is shown in FIG. ). For the outer seal member 50, only the vicinity of the leveling member 60 is shown.
The outer seal member 50 and the leveling member 60 are made of an elastic material such as soft rubber or soft resin. The material of the outer seal member 50 and the material of the leveling member 60 may be changed.
[0016]
The outer seal member 50 is integrally formed with a band-shaped base 51, an elastic leg 52 connected to the inner periphery of the base 51 and the width center, and an elastic lip 53 connected to the widthwise edge of the outer periphery of the base 51. It is an elongate seal member.
The leveling member 60 extends in substantially the same direction as the outer seal member 50. Such a leveling member 60 is formed integrally with the outer seal member 50 as described above, and (1) the cross-sectional shape near the boundary A with the outer seal member 50 is the cross-sectional shape of the outer seal member 50. They are almost the same, and (2) they become wider as they move away from the boundary A, and (3) the cross-sectional shape changes.
[0017]
Specifically, the leveling member 60 has a belt-like base 61, an elastic leg 62 connected to the inner periphery of the base 61 and the center of the width, and an elastic lip 63 connected to the edge in the width direction of the outer periphery of the base 61.

The cross-sectional shape and dimensions of the first area B are substantially the same as the cross-sectional shape and dimensions of the outer seal member 50. In the second area C, the edge 65 of the base 61 opposite to the elastic lip 63 is extended to be wide, the vertical wall 66 extends downward from the edge 65, and the base 61 extends along the base 61 from the lower end of the vertical wall 66. The U-shaped cross section 68 is formed by extending the folded portion 67. The third area D has substantially the same shape as the cross-sectional shape of the second area C, and further has a vertical edge 69 extending downward from the end of the folded portion 67. In the fourth area E, the length of the vertical wall 66 is larger than that of the second and third areas C and D, and the fourth area E is formed in a cross-sectional shape in which the folded portion 67 and the vertical edge portion 69 are not provided. Reference numeral 71 denotes a clip hole.

(E) extends the inner panel 33 halfway along the inner side of the vertical wall 66, and extends a part of the vertical wall 66 toward the door panel 31, between the inner panel 33 and the end of the door lining material 34. It shows that the vertical wall 66 has been sandwiched. Since the elastic leg portion 62 is attached to the fitting groove 42 by fitting and a part of the vertical wall 66 is attached by being sandwiched, the leveling member 60 can be reliably attached to the door 12. Since it attaches reliably, the external appearance property of the whole door 12 also increases. The compression allowance of the inner seal member 25 in this cross section, that is, the overlap allowance between the tip of the inner seal member 25 and the contact surface 66a of the vertical wall 66 is Pe.
[0026]
(F) shows that the inner panel 33 extends to the outer peripheral surface of the sash 41 through the inside of the base portion 61 and the inside of the vertical wall 66. Also in this cross section, the vertical wall 66 is sandwiched between the inner panel 33 and the end of the door lining material 34. In this cross section, the compression allowance of the inner seal member 25, that is, the overlap allowance between the tip of the inner seal member 25 and the contact surface 66a of the vertical wall 66 is Pf.
[0027]
(G) is the length of the vertical wall 66 which extends the inner panel 33 further so as to wrap the entire outer peripheral surface of the sash 41 and is inserted between the inner panel 33 and the end of the door lining material 34. Indicates that the value is reduced. The compression allowance of the inner seal member 25 in this cross section, that is, the overlap allowance between the tip of the inner seal member 25 and the contact surface 66a of the vertical wall 66 is Pg.
[0028]
(H) shows that the vertical wall 66 is shortened so as to be detached from the inner seal member 25, and the base portion 61 is fixed to the inner panel 33 by the clip 81. The inner seal member 25 contacts the inner surface of the inner panel 33. In this cross section, the compression allowance of the inner seal member 25, that is, the overlap allowance between the tip of the inner seal member 25 and the inner surface (seal surface 36) of the inner panel 33 is Ph.
[0029]
All the compression allowances of the inner seal member 25 indicated by symbols Pa to Ph are set to be substantially the same. That is, the seal surface 36 is made substantially flat with respect to the tip of the inner seal member 25 so that all the compression allowances Pa to Ph are substantially uniform. Specifically, in each part (b) to (h), the position of the contact surface 66a of the vertical wall 66 is changed by appropriately changing the width of the base 61 of the leveling member 60. By changing the position of the contact surface 66a, the step 46 between the inner surface of the sash 41 and the inner surface of the inner panel 33 can be eliminated. Since the compression allowances Pa to Ph are substantially uniform, the sealing performance of the inner seal member 25 is extremely good.
