DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A seal structure for a door car with a sash according to a first embodiment of the present invention will be described with reference to FIG. FIG. 5 is an enlarged sectional view taken along the line BB of FIG. 1 showing a seal structure of the door car with a sash according to the first embodiment of the present invention. The same parts as those of the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

The seal structure of the sash-equipped door car according to the embodiment of the present invention is similar to that shown in the conventional example, and the sash 5 peripheral edge above the belt line BL and the door 1 below the belt line BL of the sash-equipped door car. Along the periphery, a door weather strip 3 in which a main seal portion 7 having a hollow cross section and a sub-seal portion 8 having a lip cross section are integrally formed with the mounting base 6 is mounted. When the door is closed, a seal line is provided so that the sub-seal portion 8 is elastically contacted from the rear side of the vehicle body pillar panel, and the main seal portion 7 of the door weather strip 3 located on the hinge portion side when the door is closed is attached to the door 1. The sub-seal portion 8 extending from the upper part of the belt line BL to the lower hinge part is set to be bent substantially perpendicularly to the closing locus.
It is designed to make a continuous contact with 0.

In this embodiment, as shown in FIG. 5, the body facing the hinge of the door 1 is opposed to the peripheral edge of the door 1 so that the seal line of the sub-seal portion 8 is elastically contacted from the rear side of the vehicle body pillar panel. The surface 20A of the panel 20 projects outward from the base of the sub-seal portion 8 so that the sub-seal portion 8 elastically contacts the side surface 20B on the door 1 side of the surface 20A of the projecting body panel 20 when the door is closed. I have to.

According to this, as in the conventional example, the periphery of the sash 5 above the belt line BL is double-sealed by the main seal portion 7 and the sub-seal portion 8 of the door weather strip 3 elastically contacting the body panel 20. You. A door weather strip 3 which is continuous from the sash 5 above the belt line BL and has a common cross section is attached to the periphery of the door 1 below the belt line BL, and a body panel surface 20A protrudes from the hinge side. Because
Also on the hinge part side, the main seal part 7 and the sub seal part 8 are double-sealed by elastically contacting the surface of the body panel 20 on which the sash 5 is provided, in the same manner as the peripheral edge of the sash 5. Therefore, even if high-pressure water W due to car washing or the like is applied to the hinge portion, the pressure is relieved by the sub-seal portion 8, so that the water is removed from the main seal portion 7 and the body panel 2.
It is prevented from entering the vehicle interior from between 0.

Here, the sub-seal portion 8 has a substantially central portion P curved substantially toward the main seal portion 7 (upward in FIG. 4), and a main seal portion side Q at the front end portion at the periphery of the sash 5. Surface 20B which is the opening edge of body panel 20 (FIG. 3)

Therefore, when the high-pressure water W is applied to the sub-seal portion 8 by a car wash or the like, the force acts in a direction in which the substantially rectangular shape is further curved, and the force of the leading end portion elastically contacting the opening edge of the body panel increases. In addition, the sealing property is further improved.

As shown in FIG. 5, at least on the hinge side, the sub-seal portion 8 is moved from the opening edge of the body panel 20 toward the interior of the vehicle body when the door is closed. On the side 20, an elastic contact surface of the sub-seal portion 8 is provided separately from the elastic contact surface of the main seal portion 7, and the elastic contact surface of the sub-seal portion 8 determines the distance between the main seal portion 7 and the surface facing the door panel. It is wider by a distance L than the contact surface. As a result, when the door is closed, the sealing properties of the sub-seal sections 8 are not weakened due to the elastic contact of the main seal sections 7, and the sealing properties of the respective sub-seal sections 8 are sufficiently exhibited.

Next, a seal structure of a door car with a sash according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a BB diagram of FIG. 1 showing a seal structure of a door car with a sash according to a second embodiment of the present invention.

This is because the inner sealing type sub-sealing portion 8 of the first embodiment is replaced with the outer sealing type sub-sealing portion 18 and the sub-sealing portion is provided between the main sealing portion 17 and the sub-sealing portion 18 on the body panel 20 on the hinge portion side. An inclined portion 20B elastically contacting the portion 18 is formed.
The sub-seal portion 18 covers the outside corner of the body panel 20 on the roof side (FIG. 7), and at least covers the outside corner of the body panel 20 also on the hinge side (FIG. 6). . The inclined portion 20B is a surface that is inclined by the projecting portion of the body panel 20 in a direction going forward of the vehicle toward the outside of the vehicle.

As described above, since the sub-seal portion 18 is of an outer covering type that covers the outer corners of the body panel 20 on both the roof portion and the hinge portion when the door is closed, high-pressure water due to car washing or the like is applied to the sub-seal portion 18. In this case, a force acts in a direction to press the sub-seal portion 18 from the outside, so that the sealing performance is further improved. In addition, since the inclined portion 20B is formed on the surface of the body panel 20 elastically contacting the sub-seal portion 18 on the hinge portion side, for example, as shown in FIG.
There is no danger that the distal end of the sub-seal portion 28 may be rolled into the vehicle interior due to the high pressure of the high-pressure water W to cause deterioration of the sealing performance.

As described above, according to the first aspect of the present invention, the seal line is provided such that the sub-seal portion from the upper portion to the lower hinge portion of the belt line is elastically contacted from the rear side of the vehicle body pillar panel. Therefore, when the door is closed, the hinge portion having weak sealing properties is double-sealed by the sub-seal portion together with the main seal portion set to bend substantially perpendicularly to the closing locus of the door. Therefore, even if high-pressure water from a car wash or the like is applied to the hinge portion, the pressure is alleviated by the sub-seal portion, so that water is prevented from entering the vehicle interior from between the main seal portion and the body panel.

According to the second aspect of the present invention, the surface of the body panel facing the periphery of the door on the hinge portion side of the door is protruded outward from the base of the sub-seal portion, and the hinge portion when the door is closed. The sub-seal part located on the side is elastically contacted with the surface of the protruding body panel,
The hinge portion having weak sealing properties is double-sealed by the main seal portion and the sub-seal portion of the door weather strip, similarly to the sash peripheral edge. Therefore, even if high-pressure water from a car wash or the like is applied to the hinge portion, the pressure is alleviated by the sub-seal portion, so that water is prevented from entering the vehicle interior from between the main seal portion and the body panel.

According to the third aspect of the present invention, in addition to the effects of the second aspect of the present invention, since the sub-seal portion is of an internal contact type, when high-pressure water from a car wash or the like is applied to the sub-seal portion. In this case, since a force acts in a direction in which the substantially rectangular shape is further curved or bent, the force of elastically contacting the opening edge of the body panel also increases, so that the sealing performance is further improved. Also, at least on the hinge portion side, the body panel side has an elastic contact surface of the main seal portion so that the sub-seal portion is movable toward the vehicle interior from the opening edge of the body panel when the door is closed. Separately, an elastic contact surface of the sub seal portion is provided, and the distance between the elastic contact surface of the sub seal portion and the surface facing the door panel is wider than the elastic contact surface of the main seal portion. The sealing properties of the sub-seal portions are not weakened by the elastic contact, and the sealing properties are sufficiently exhibited.

According to the fourth aspect of the present invention, in addition to the effects of the second aspect of the present invention, since the sub-seal portion is of an outer covering type, when high-pressure water from a car wash or the like is applied to the sub-seal portion. In the above, a force acts in a direction to press the sub-seal portion from the outside, and the sealing performance is further improved. In addition, since the inclined portion is formed on the surface of the body panel elastically contacting the sub-seal portion on the hinge portion side, there is no possibility that the leading end portion of the sub-seal portion is involved and the sealing performance is reduced.
