Abstract

A vehicle door sash structure includes a holding unit. The holding unit includes a guide locking portion arranged in a region of a run channel opposed in a vehicle inner-outer direction to a tip end rim of an inner beam portion in a state of temporary attachment after completion of attachment of a molding to an outer beam portion. The guide locking portion is inclined in a direction to guide the run channel to a position of completion of attachment while coming into contact with the tip end rim of the inner beam portion by an input of an attachment force in a direction to attach the molding to the run channel in the state of temporary attachment.

Claims

1. A vehicle door sash structure provided with

a window glass arranged in a window frame,

a rail portion constituting the window frame and surrounding a rim of the window glass,

a molding constituting an outer wall of the rail portion,

a window frame body constituting an inner wall of the rail portion, and

a run channel arranged in the rail portion,

the vehicle door sash structure comprising:

a molding assembly including the molding and the run channel integrated together and being attached to the window frame body from a vehicle outer side to a vehicle inner side in a vehicle inner-outer direction along a direction from an inner side to an outer side of a vehicle;

an outer beam portion taking on a form of a cantilever erected on the window frame body so as to be capable of attaching the molding;

an inner beam portion taking on a form of a cantilever erected on the window frame body; and

a holding unit provided on the run channel and configured to be lockable with the inner beam portion,

wherein

the holding unit includes a guide locking portion arranged in a region of the run channel opposed in the vehicle inner-outer direction to a tip end rim of the inner beam portion in a state of temporary attachment after completion of attachment of the molding to the outer beam portion,

the guide locking portion is inclined in a direction to guide the run channel to a position of completion of attachment while coming into contact with the tip end rim of the inner beam portion by an input of an attachment force in a direction to attach the molding to the run channel in the state of temporary attachment,

the run channel includes a restorative biasing portion provided between a bottom portion constituting a bottom part of the rail portion and an inner wall portion constituting an inner wall part of the rail portion,

the restorative biasing portion includes

a corner part elastic body which is held and biased between the bottom portion and the inner wall portion at the position of completion of attachment;

a bottom side bending part which joins the bottom portion to the corner part elastic body; and

an inner wall side bending part which joins the inner wall portion to the corner part elastic body, and

the bottom side bending part and the inner wall side bending part are formed thinner than remaining regions of the run channel.

2. The vehicle door sash structure according to claim 1, wherein the guide locking portion includes a locking projection provided at an end rim on the vehicle outer side in the vehicle inner-outer direction and lockable with a plate surface part of the inner beam portion.

3. The vehicle door sash structure according to claim 1, wherein

the window frame body is formed by bending at least one plate member, and

an end rim of the inner beam portion takes on a stepped shape obtained by allowing joining margins set on end rims of the plate member to overlap each other in such a way as to be displaced along the inclination of the guide locking portion.

4. The vehicle door sash structure according to claim 1, wherein

the restorative biasing portion is fitted into the rail portion while being elastically deformed, and

the molding is biased to the outer side in the vehicle inner-outer direction in a state of being fitted to the window frame body by resilience of the restorative biasing portion, and is biased to and held at the position of completion of attachment in a state of being engaged with the outer beam portion.

5. The vehicle door sash structure according to claim 1, wherein the restorative biasing portion is substantially formed to be a Tr shape.

6. The vehicle door sash structure according to claim 1, wherein the molding assembly further includes a molding body and a molding elastic beam which is erected on a vehicle inner side surface of the molding body in the vehicle inner-outer direction toward the vehicle inner side in the vehicle inner-outer direction,

wherein the molding elastic beam includes a molding locking claw and a locking claw elastic contact spring at its tip end, and an elastic contact spring on its frame inner side surface in the frame inner-outer direction, and

wherein the outer beam portion includes an outer beam engaging projection at its vehicle inner side surface in the vehicle inner-outer direction, the outer beam engaging projection being engageable with the molding locking claw.
