BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to vehicle press door structure and a door glass run. More particularly, the invention relates to a vehicle press door structure in which a door glass run has been fit into a door frame, and the door glass run.

2. Description of Related Art

Japanese Patent Application Publication No. 2005-263062 (JP 2005-263062 A) describes a press door type door of a vehicle. A door frame of this door is formed by a door outer panel and a door inner panel. A door glass run is attached to an inner periphery of the door frame. The door glass run forms a seal between the door frame and a door glass when a window is closed.

The door frame is a channelless door frame in which a channel member having a recessed sectional shape that supports a base portion of a door glass run main body is not provided on an inner peripheral side. However, with this door frame, there is a space between the base portion of the door glass run main body and an inside wall of the door frame. As a result, there is room for improvement with respect to noise and water getting into the vehicle from outside the vehicle through this space in the door frame.

SUMMARY OF THE INVENTION

The invention thus provides a vehicle press door structure and a door glass run capable of improving sound insulation performance and watertight performance between a door frame and a door glass run.

A first aspect of the invention relates to a vehicle press door structure that includes a door frame in which an open portion having a recess-shaped cross-section that is open to an inner peripheral side is formed by a door outer panel, and a door inner panel arranged on a vehicle width direction inside of the door outer panel; a door glass run that has lip portions that respectively extend toward a center side from both side portions of a door glass run main body having a recess-shaped cross-section and slidingly contact a door glass, the door glass run being fit into the open portion with a base portion between both of the side portions of the door glass run main body opposing an inside wall of the door inner panel; and a seal portion that protrudes from the base portion and contacts the inside wall, and extends in a length direction of the door glass run main body.

In this aspect, the door frame is formed by the door outer panel and the door inner panel. The open portion having a recess-shaped cross-section that is open to the inner peripheral side is provided on this door frame. The door glass run is fit into the open portion. The door glass run has the lip portions that respectively extend toward the center side from both side portions of the door glass run main body having a recess-shaped cross-section and slidingly contact a door glass. The base portion of the door glass run main body opposes the inside wall of the door inner panel.

Here, the seal portion is provided on the door glass run. The seal portion protrudes from the base portion of the door glass run main body and contacts the inside wall of the door inner panel, and extends in a length direction of the door glass run main body. Therefore, between the inside wall of the door inner panel and the base portion of the door glass run main body is blocked off in the length direction of the door glass run main body by the seal portion. Accordingly, noise and water are effectively inhibited from getting into the vehicle from outside the vehicle, in the door frame.

The vehicle press door structure according to this aspect has a beneficial effect in which sound insulation performance and watertight performance between the door frame and the door glass run are able to be improved.

In the aspect described above, the seal portion may include a vehicle outside seal portion that protrudes from a vehicle width direction outside of the base portion, and a vehicle inside seal portion that protrudes farther from the vehicle width direction inside than the vehicle outside seal portion. The vehicle outside seal portion and the vehicle inside seal portion may have a shape in which a separation distance therebetween gradually becomes wider or narrower toward the inside wall.

According to this structure, the seal portion includes the vehicle outside seal portion and the vehicle inside seal portion. Therefore, between the inside wall of the door inner panel and the base portion of the door glass run main body is doubly blocked off from outside the vehicle toward the inside of the vehicle. Also, the vehicle outside seal portion and the vehicle inside seal portion of the seal portion are shaped such that the separation distance therebetween becomes wider or narrower toward the inside wall. Therefore, the vehicle outside seal portion and the vehicle inside seal portion contact the inside wall at an angle, and thus have a cushioning characteristic in which they will easily deform. As a result, the contact area between the inside wall and the vehicle outside seal portion and the vehicle inside seal portion is increased, and the airtightness of the contact portion is improved. Therefore, the sealing characteristic between the door frame and the door glass run is able to be improved even more.

With a vehicle press door structure having this structure, the sealing characteristic between the door frame and the door glass run is further improved, so sound insulation performance and watertight performance are able to be even further improved.

In the aspect described above, the door outer panel may include a vehicle outside engageable portion in which an end portion on the inner peripheral side of the door outer panel is bent toward the vehicle width direction inside. Also, a vehicle outside side portion of the door glass run main body, which is positioned on a vehicle width direction outside of both of the side portions of the door glass run main body, may include a vehicle outside engaging portion that engages with the vehicle outside engageable portion, and that fits the door glass run into the open portion.

According to this structure, the vehicle outside engageable portion is provided on the door outer panel, and the vehicle outside engaging portion is provided on the vehicle outside side portion of the door glass run main body. The door glass run is fit into the open portion by the vehicle outside engaging portion engaging with the vehicle outside engageable portion.

Here, the vehicle outside engageable portion is formed with the end portion on the inner peripheral side of the door outer panel bent toward the vehicle width direction inside, and the vehicle outside engaging portion is formed on the vehicle outside side portion of the door glass run main body that is fit into the open portion. Also, the door glass run is fit into the open portion by the vehicle outside engaging portion engaging with the vehicle outside engageable portion in the open portion. Therefore, there is no need for a vehicle outside molding portion that extends to the design surface of the door outer panel on the vehicle outside side portion of the door glass run main body. Thus, instead of the step between the vehicle outside molding portion and the door glass, there is a step between the door glass and the design surface of the door outer panel, so this step is reduced.

With the vehicle press door structure having this structure, the step to the door glass in the door frame is reduced, so wind disturbance around the door frame is effectively suppressed. As a result, wind noise and air resistance are able to be reduced.

In the structure described above, a bent extended portion in which the door inner panel curves and extends toward the inner peripheral side may be provided on an edge portion of the door inner panel on the vehicle width direction inside, which opposes the base portion. Also, the bent extended portion, the inside wall, and an inside wall of the door outer panel may form a housing and retaining portion that at least houses the base portion, and retains the door glass run main body by pushing the door glass run main body against the inside wall of the door outer panel.

According to this structure, the bent extended portion in which the door inner panel curves and extends toward the inner peripheral side is provided on an edge portion of the door inner panel on the vehicle width direction inside, which opposes the base portion. This bent extended portion, together with the inside wall of the door inner panel, and the inside wall of the door outer panel, forms the housing and retaining portion. Here, in the housing and retaining portion, at least the base portion of the door glass run main body is housed, and the door glass run main body is retained pressed against the inside wall of the door outer panel. Therefore, the fitting position and orientation of the door glass run are determined with the housing and retaining portion as a reference, and the door glass run is retained in this determined fitting position and orientation.

The vehicle press door structure having this structure is provided with the housing and retaining portion, and thus has a beneficial effect in which the posture retaining force of the door glass run in the door frame is able to be improved.

In the structure described above, the vehicle outside seal portion and the vehicle inside seal portion may have a shape in which a separation distance therebetween gradually becomes wider toward the inside wall, and a tip end in a protruding direction of the vehicle inside seal portion may be elastically pressed against the bent extended portion.

According to this structure, the vehicle outside seal portion and the vehicle inside seal portion are shaped such that the separation distance between them gradually increases toward the inside wall. Here, the tip end in the protruding direction of the vehicle inside seal portion of the seal portion elastically pressed against the bent extended portion. Therefore, the door glass run main body is pressed toward the inside wall of the door outer panel via the vehicle inside seal portion by the bent extended portion, so fitting position and orientation of the door glass run are determined with the inside wall of the door outer panel as a reference, and the door glass run is retained in this determined fitting position and orientation.

The vehicle press door structure having this structure is provided with the bent extended portion and the vehicle inside seal portion, the tip end in the protruding direction of which is positioned against the bent extended portion, so the posture retaining force of the door glass run in the door frame is able to be improved.

In the structure described above, a portion on the vehicle width direction inside of the door inner panel may be formed with a U-shaped cross-section that is open on the open portion side and protrudes toward the vehicle width direction inside, and an inside wall of an edge portion on the open portion side of the door inner panel may be a vehicle inside engageable portion. Also, a vehicle inside engaging portion that is engaged with the vehicle inside engageable portion and fits the door glass run into the open portion may be provided on an end portion on a side opposite the base portion, of a vehicle inside side portion that is positioned on the vehicle width direction inside of both of the side portions of the door glass run main body.

According to this structure, the vehicle inside engageable portion is provided on the door inner panel, and the vehicle inside engaging portion is provided on the vehicle inside side portion of the door glass run main body. The door glass run is fit into the open portion by the vehicle inside engaging portion engaging with the vehicle inside engageable portion.

Here, the portion of the door inner panel on the vehicle width direction inside is formed having a U-shaped cross-section that is open on the open portion side and protrudes toward the vehicle width direction inside. Also, the vehicle inside engageable portion is the inside wall of the edge portion on the open portion side of the door inner panel. Meanwhile, the vehicle inside engaging portion is provided on the end portion of the vehicle inside side portion of the door glass run main body. Also, the door glass run is fit into the open portion by the vehicle inside engaging portion engaging with the vehicle inside engageable portion inside the open portion. Therefore, there is no need for the vehicle inside molding portion for fitting the door glass run and that extends toward the design surface of the door inner panel on the vehicle inside side portion of the door glass run main body, or the protruding amount of the vehicle inside molding portion toward the design surface is reduced.

The vehicle press door structure having this structure has a beneficial effect in which the sectional shape of the door frame is able to be made compact.

A second aspect of the invention relates to a door glass run. This door glass run includes i) a door glass run main body that is fit into the open portion of the door frame according to the aspect described above, and that has lip portion that respectively extend toward a center side from both side portions having a recess-shaped cross-section and slidingly contact the door glass, and also has a base portion between both of the side portions; and ii) a seal portion that protrudes from the base portion and contacts an inside wall of the door inner panel, and extends in a length direction of the door glass run main body.

This aspect is able to display the same operation as that obtained by the vehicle press door structure described above.

DETAILED DESCRIPTION OF EMBODIMENTS

First Example Embodiment

A vehicle press door structure according to a first example embodiment of the invention will now be described with reference toFIGS. 1 to 7. In the drawings, arrow FR indicates a vehicle forward side, and arrow UP indicates a vehicle upward side. Also, arrow IN indicates a vehicle width direction inside, i.e., a vehicle cabin inside.

(General Structure of Vehicle)

As shown inFIG. 1, a vehicle10to which a vehicle press door structure according to this example embodiment has been applied is a four-door type vehicle, and includes a side door12. The side door12includes a door main body16that forms a vehicle body side portion and in which is housed a window regulator and the like, not shown, that raises and lowers a door glass14, and a door frame18provided on an upper portion of this door main body16. A window opening20is formed surrounded by an upper edge (door belt molding)16A of the door main body16and an inner peripheral edge18A of the door frame18. The window opening20is able to open and close by raising and lowering of the door glass14.

(Structure of the Door Frame)

As shown inFIG. 2, the door frame18includes a plate-shaped door outer panel22that extends with a direction along a peripheral edge of the window opening20as the length direction, and of which a vehicle outside surface is a design surface, and a door inner panel24that is arranged on a vehicle width direction inside of this door outer panel22, and of which a vehicle inside surface is a design surface. An open portion34having a recessed cross-section that opens to an inner peripheral side (i.e., the inner peripheral edge18A side) is formed in this door frame18. A door glass run40is fit into this open portion34.

As shown inFIGS. 2, 4, and 5, an outer peripheral end portion22A of the door outer panel22is joined to an outer peripheral end portion24A of the door inner panel24by seaming. An inner peripheral end portion22B of the door outer panel22that will be the inner peripheral side of the door frame18(i.e., the inner peripheral edge18A side) is folded back toward the vehicle width direction inside by hemming. This bent terminal portion is a vehicle outside engageable portion26.

As shown inFIGS. 2, 4, and 6, the outer peripheral end portion24A of the door inner panel24extends contacting an inside wall22C of the door outer panel22until an intermediate portion of the outer peripheral end portion22A and the inner peripheral end portion22B of the door outer panel22. The door inner panel24includes this outer peripheral end portion24A, a lateral wall24B in which an inner peripheral side end of the door frame18of the outer peripheral end portion24A is folded back toward the vehicle width direction inside, an inclined wall24C in which a vehicle width direction inside end (edge portion) of the lateral wall24B extends curved toward the inner peripheral side, and a doubled-back wall24D that has a U-shaped cross section, and that is provided protruding toward the vehicle width direction inside from an inner peripheral side end of the inclined wall24C, with the open portion34side open. Also, an edge portion24E on the open portion34side of the doubled-back wall24D bent back slightly toward the outer peripheral side of the door frame18, and an inside wall of the edge portion24E that opposes an inside wall28of the lateral wall24B is a vehicle inside engageable portion32.

As shown inFIGS. 2 and 4, the inside wall28of the lateral wall24B of the door inner panel24is a bottom wall of the open portion34. This inside wall28opposes a back surface of a base portion44of the door glass run40. Between the lateral wall24B and the inclined wall24C is a bent extended portion30having an inverted V-shaped cross-section. In this example embodiment, a housing and retaining portion70that has an inverted L-shaped cross-section, houses at least the base portion44of the door glass run40, and retains a door glass run main body42by pushing it (i.e., the door glass run main body42) against the door outer panel22, is formed inside the open portion34by the inside wall28of the door inner panel24, the bent extended portion30, and the base portion44of the door glass run40.

(Structure of the Door Glass Run)

The door glass run40includes the door glass run main body42that is formed extending in the length direction of the door frame18shown inFIG. 1, and has a recess-shaped cross-section that is open to the inner peripheral side of the door frame18as shown inFIGS. 2 to 6. This door glass run main body42includes as main constituent elements the base portion44, a vehicle outside side portion46and a vehicle inside side portion48as both side portions, and a vehicle outside lip portion50and a vehicle inside lip portion52as lip portions. The base portion44is a portion that corresponds to a bottom portion of the door glass run main body42, which has a recess-shaped cross-section, and opposes the inside wall28of the lateral wall24B of the door inner panel24at a slight distance. The one vehicle outside side portion46is provided protruding toward the inner peripheral side from the end portion of the base portion44on the vehicle width direction outside, and is integrally formed with the base portion44. The other vehicle inside side portion48is also provided protruding toward the inner peripheral side from the end portion, substantially parallel to the vehicle outside side portion46of the base portion44, in a position farther toward the vehicle width direction inside than the vehicle outside side portion46, and is also integrally formed with the base portion44. The vehicle outside lip portion50and the vehicle inside lip portion52each extend toward the center side from both side portions, i.e., the vehicle outside side portion46and the vehicle inside side portion48, and slidingly contact the door glass14. The vehicle outside lip portion50is integrally formed with the inner peripheral side end of the vehicle outside side portion46. Also, the vehicle inside lip portion52is integrally formed with the inner peripheral side end of the vehicle inside side portion48. The door glass run40is manufactured by extrusion molding rubber material.

As shown inFIGS. 2 to 4, the door glass run main body42is provided with a vehicle outside seal portion64and a vehicle inside seal portion66as seal portions that protrude from the base portion44and contact the inside wall28, and extend in the length direction of the door glass run main body42. The vehicle outside seal portion64is integrally formed with the base portion44, and protrudes toward the inside wall28from the vehicle width direction outside of this base portion44. The vehicle inside seal portion66is similarly integrally formed with the base portion44, and protrudes toward the inside wall28from farther on the vehicle width direction inside than the vehicle outside seal portion64of this base portion44. In this example embodiment, the vehicle outside seal portion64and the vehicle inside seal portion66are shaped such that the separation distance therebetween gradually becomes wider toward the inside wall28. In particular, as shown inFIG. 4, when the door glass run40is fit into the open portion34of the door frame18, the vehicle outside seal portion64and the vehicle inside seal portion66contact the inside wall28and elastically deform so as to be in tight contact with the inside wall28(i.e., are elastically pressed against the inside wall28). Also, a tip end portion in the protruding direction of the vehicle inside seal portion66contacts the bent extended portion30between the lateral wall24B and the inclined wall24C of the housing and retaining portion70. At this bent extended portion30, movement of the tip end portion in the protruding direction of the vehicle inside seal portion66toward the vehicle width direction inside is restricted, such that reaction force against the elastic deformation is generated in the vehicle inside seal portion66. This reaction force acts to push the door glass run main body42against the inside wall22C of the door outer panel22via the vehicle inside seal portion66.

As shown inFIGS. 2 to 5, a vehicle outside engaging portion54that protrudes toward the inside wall22C side of the door outer panel22and is engaged with the vehicle outside engageable portion26, is integrally formed on the end portion of the vehicle outside side portion46that is on the base portion44side. The vehicle outside engaging portion54is set to at least the same protruding amount as the dimensions of the vehicle outside engageable portion26(which corresponds to the plate thickness of the door outer panel22). Also, in other words, the vehicle outside engaging portion54is formed by recessing the vehicle outside side portion46to match the folded back position of the inner peripheral end portion22B of the door outer panel22that been hemmed. When the vehicle outside engaging portion54is engaged with the vehicle outside engageable portion26, the door glass run40is inhibited from slipping out of the open portion34, and the door glass run40is able to be fit into the open portion34. Meanwhile, a vehicle outside retaining portion56that protrudes out toward the door outer panel22side and engages with the inner peripheral edge18A of the inner peripheral end portion22B, is integrally formed on an end portion of the vehicle outside side portion46that is on the side opposite the vehicle outside engaging portion54. The vehicle outside retaining portion56is configured to retain (i.e., grip) the inner peripheral edge18A so that the vehicle outside side portion46will stay on the door outer panel22even if the door glass14shown inFIGS. 2 and 5pushes the vehicle outside lip portion50up when the window is closed. Also, a protrusion58that regulates the distance between the vehicle outside side portion46and the inner peripheral end portion22B is integrally formed on the inner peripheral end portion22B side of the vehicle outside side portion46, at an intermediate portion between the vehicle outside engaging portion54and the vehicle outside retaining portion56.

As shown inFIGS. 2 and 6, a vehicle inside engaging portion60that protrudes toward an inside wall side of the edge portion24E of the door inner panel24and engages with the vehicle inside engageable portion32is integrally formed with an end portion of the vehicle inside side portion48that is on the side opposite the base portion44, i.e., on the tip end portion in the protruding direction. When the vehicle inside engaging portion60engages with the vehicle inside engageable portion32, the vehicle inside side portion48bows between the inclined wall24C and the edge portion24E in the open portion34, thus inhibiting the door glass run40from coming out of the open portion34, and enabling the door glass run40to be fit into the open portion34. Meanwhile, the end portion of the vehicle inside side portion48branches off from a base position of the vehicle inside engaging portion60, and the vehicle inside lip portion52and a vehicle inside retaining portion62are integrally formed on this base portion. The vehicle inside retaining portion62extends a certain amount on the design surface on the vehicle cabin inside of the edge portion24E of the door inner panel24that will be the back surface side of the vehicle inside engageable portion32, and just sandwiches (holds tightly) the edge portion24E with the vehicle inside engaging portion60. Similar to the vehicle outside retaining portion56, the vehicle inside retaining portion62retains the vehicle inside side portion48so that it will stay on the door inner panel24even if the door glass14pushes the vehicle inside lip portion52up when the window is closed.

As shown inFIGS. 2 to 4andFIG. 6, a door glass end seal portion68that protrudes toward the center side of the vehicle outside side portion46and the vehicle inside side portion48is integrally formed on a joining portion of the base portion44and the vehicle inside side portion48. When the window is closed, the door glass end seal portion68contacts the end portion of the door glass14and elastically deforms, and is thus in tight contact, with the door glass14.

(Operation and Effect of this Example Embodiment)

With the vehicle press door structure according to this example embodiment, the door frame18shown inFIGS. 1 and 2is formed by the door outer panel22and the door inner panel24. The open portion34having a recessed cross-section that opens to the inner peripheral side (i.e., the inner peripheral edge18A side), as shown inFIG. 2in particular, is provided on this door frame18. The door glass run40is fit into the open portion34. The door glass run40has the vehicle outside lip portion50and the vehicle inside lip portion52, both of which extend toward the center side from both side portions (i.e., the vehicle outside side portion46and the vehicle inside side portion48) of the door glass run main body42that has a recessed cross-section, and that slidingly contact the door glass14. The base portion44opposes the inside wall28of the door inner panel24.

Here, the vehicle outside seal portion64and the vehicle inside seal portion66as seal portions are provided on the door glass run40, as shown inFIGS. 2 to 6. The vehicle outside seal portion64and the vehicle inside seal portion66protrude from the base portion44of the door glass run main body42, and contact the inside wall28of the inside wall28, while extending in the length direction of the door glass run main body42. Therefore, between the inside wall28of the door inner panel24and the base portion44of the door glass run main body42is blocked off in the length direction of the door glass run main body42by the vehicle outside seal portion64and the vehicle inside seal portion66(seeFIGS. 2 and 4in particular). Accordingly, noise and water are effectively inhibited from getting into the vehicle from outside the vehicle, in the door frame18.

FIG. 7is a diagram illustrating the relationship between acoustic sensitivity (dB) and ⅓ octave center frequency (Hz) to illustrate sound insulation performance. InFIG. 7, actually measured data A shown by the solid line is the result from measuring noise generated from outside a vehicle in the vehicle, for the door frame18to which the vehicle press door structure according to this example embodiment has been applied. Also, actually measured data B is the measurement result of a case in which the vehicle press door structure according to the example embodiment is not applied. With the measurements here, the results show that noise penetration within a range up to 2500 Hz is significantly reduced.

Therefore, with the vehicle press door structure according to this example embodiment, sound insulation performance and watertight performance between the door frame18and the door glass run40are able to be improved.

Also, as shown inFIGS. 2, 4, 5, and 6, with the vehicle press door structure according to this example embodiment, when the door glass14is closed, the raising/lower force (pressure) of the door glass14is received, via the base portion44of the door glass run main body42, the vehicle outside seal portion64, and the vehicle inside seal portion66, by the inside wall28of the door inner panel24that is more rigid (harder) than these. Therefore, deformation of the door glass run40that will cause it to come out of the open portion34is inhibited. More specifically, the vehicle outside retaining portion56is inhibited from coming off of the inner peripheral end portion22B, and the vehicle inside retaining portion62is inhibited from coming off of the edge portion24E. Therefore, the door glass run40is stably retained in the open portion34of the door frame18.

Moreover, with the vehicle press door structure according to this example embodiment, when the door glass14is closed, the raising/lower force (pressure) of the door glass14is used as seal pressure that presses the vehicle outside seal portion64and the vehicle inside seal portion66against the inside wall28of the door inner panel24. Therefore, airtightness between the inside wall28and the vehicle outside seal portion64and the vehicle inside seal portion66is improved, and the seal area between the inside wall28and the vehicle outside seal portion64and the vehicle inside seal portion66increases with elastic deformation of the vehicle outside seal portion64and the vehicle inside seal portion66. Therefore, the sealing characteristic between the door frame18and the door glass run40is able to improved even more.

Also, as shown inFIGS. 2 and 6, with the vehicle press door structure according to this example embodiment, the distance between the base portion44of the door glass run main body42and the inside wall28of the door inner panel24is reduced enough so that the vehicle outside seal portion64and the vehicle inside seal portion66contact the inside wall28. Therefore, the space between the back surface of the door glass run40and the door frame18is reduced, so the sectional shape of the door frame18is able to be made compact. Also, because the sectional shape of the door frame18is compact, the appearance of the vehicle10is nicer, and the appearance design of the door frame18is improved.

Moreover, with the vehicle press door structure according to this example embodiment, as shown inFIGS. 2 to 4, the seal portion includes the vehicle outside seal portion64and the vehicle inside seal portion66. Therefore, between the inside wall28of the door inner panel24and the base portion44of the door glass run main body42is doubly blocked off from the vehicle width direction outside toward the inside. Also, the vehicle outside seal portion64and the vehicle inside seal portion66of the seal portion are shaped such that the separation distance therebetween becomes wider toward the inside wall28. Therefore, the vehicle outside seal portion64and the vehicle inside seal portion66contact the inside wall28at an angle, and thus have a cushioning characteristic in which they will easily deform. As a result, the contact area between the inside wall28and the vehicle outside seal portion64and the vehicle inside seal portion66is increased, and the airtightness of the contact portion is improved. Therefore, the sealing characteristic between the door frame18and the door glass run40is able to be improved even more.

In this way, with the vehicle press door structure according to this example embodiment, the sealing characteristic between the door frame18and the door glass run40is further improved, so sound insulation performance and watertight performance are able to be even further improved.

Also, with the vehicle press door structure according to the example embodiment, as shown inFIGS. 2 to 5, the vehicle outside engageable portion26is provided on the door outer panel22, and the vehicle outside engaging portion54is provided on the vehicle outside side portion46of the door glass run main body42. Also, the door glass run40is fit into the open portion34by the vehicle outside engaging portion54engaging with the vehicle outside engageable portion26.

Here, the vehicle outside engageable portion26is formed with the inner peripheral end portion22B of the door outer panel22bent toward the vehicle width direction inside, and the vehicle outside engaging portion54is formed on the vehicle outside side portion46of the door glass run main body42that is fit into the open portion34. Also, the door glass run40is fit into the open portion34by the vehicle outside engaging portion54being engaged with the vehicle outside engageable portion26in the open portion34. Therefore, there is no need for a vehicle outside molding portion56A that extends to the design surface of the door outer panel22on the vehicle outside side portion46of the door glass run main body42, the outline of which is shown by the chain double-dashed line inFIG. 5. Thus, instead of the step between the vehicle outside molding portion56A and the door glass14, there is a step S between the door glass14and the design surface of the door outer panel22, so this step S is reduced.

Therefore, with the vehicle press door structure according to this example embodiment, the step S to the door glass14of the door frame18is reduced, so wind disturbance around the door frame18is effectively suppressed. As a result, wind noise and air resistance are able to be reduced.

Also, with the vehicle press door structure according to this example embodiment, there is no need for the vehicle outside molding portion56A shown inFIG. 5on the door glass run40, so the structure of the door glass run40is able to be simplified.

Moreover, because there is no need for the vehicle outside molding portion56A on the door glass run40, the width dimension (i.e., the dimension in the short direction) of the door outer panel22is reduced by an amount corresponding to the amount held onto by the vehicle outside molding portion56A. Therefore, the distance between the base portion44of the door glass run main body42and the inside wall28of the door outer panel22is reduced enough so that the vehicle outside seal portion64and the vehicle inside seal portion66contact the inside wall28. Therefore, the space between the back surface of the door glass run40and the door frame18is reduced, so the sectional shape of the door frame18is able to be made compact. Also, the width dimension of the door outer panel22is reduced, so the appearance of the vehicle10is nicer, and the appearance design of the door frame18is improved.

Also, the design surface of the door outer panel22of the door frame18is not covered by the vehicle outside molding portion56A, so from this perspective as well, the appearance of the vehicle is nicer, and the appearance design of the door frame18is able to be improved. Furthermore, the step S between the design surface of the door outer panel22and the door glass14is smaller, so from this perspective as well, the appearance of the vehicle is nicer, and the appearance design of the side door12is able to be improved.

Also, the vehicle inside engageable portion32is the inside wall of the edge portion24E on the open portion34side of the door inner panel24. Meanwhile, the vehicle inside engaging portion60is provided on the end portion of the vehicle inside side portion48of the door glass run main body42. Also, the door glass run40is fit into the open portion34by the vehicle inside engaging portion60engaging with the vehicle inside engageable portion32inside the open portion34. Therefore, there is no need for the vehicle inside molding portion62A that extends from the vehicle inside side portion48of the door glass run main body42toward the design surface of the door inner panel24, the outline of which is shown by the chain double-dashed line inFIG. 6. In this example embodiment, the vehicle inside retaining portion62that does not protrude as far toward the design surface is provided, so the protruding amount of the vehicle inside retaining portion62toward the design surface is less with respect to the amount holding onto the door inner panel24when the vehicle inside molding portion62A is formed.

Therefore, with the vehicle press door structure according to this example embodiment, the sectional shape of the door inner panel24is able to be made compact. Also, because the sectional shape of the door inner panel24is compact, visibility from inside the vehicle cabin to the vehicle cabin is improved. Moreover, the door glass run40is fit into the open portion34by the vehicle inside retaining portion62that protrudes less toward the design surface of the door inner panel24, so the appearance of the design surface inside the vehicle cabin is better, and thus the interior design is able to be enhanced.

Also, the door glass run40according to this example embodiment is able to obtain the same operation and effects as those obtained by the vehicle press door structure described above when fit into the open portion34of the door frame18.

Modified Example of Door Glass Run

With the door glass run40used in the vehicle press door structure according to a modified example the first example embodiment, the vehicle outside seal portion64and the vehicle inside seal portion66are shaped such that the separation distance between them gradually becomes narrower toward the inside wall28of the door inner panel24, as shown inFIG. 8. According to this door glass run40, the vehicle outside seal portion64and the vehicle inside seal portion66contact the inside wall28of the door inner panel24at an angle, and thus have a cushioning characteristic in which they will easily deform, similar to the door glass run40in the first example embodiment described above. Therefore, the sealing characteristic between the inside wall28and the door glass run40is able to be improved even more.

Second Example Embodiment
