A slider window assembly for a vehicle includes at least one fixed window panel and a movable window panel that is movable along an upper rail and a lower rail at the at least one fixed window panel between an opened position and a closed position. The lower rail includes a U-shaped channel and an attaching structure for attaching the lower rail at the at least one fixed window panel. The lower rail includes a plurality of water drainage channels established at the attaching structure and having an inlet at a wall of the U-shaped channel. A plurality of water diverters are established at the U-shaped channel and are configured to divert water flowing along the U-shaped channel toward the side of the channel along which respective inlets for respective water drainage channels are disposed.

Increase of an overall thickness of a sunroof unit is suppressed even when a flange portion depending from a side edge of an opening of a roof has a large height. A rear panel contacts an edge of an opening via a rear seal portion. The rear seal portion includes a first seal member mounted to a rear molded part in a rear portion of the opening and a second seal member extending in a fore and aft direction and supported by a frame via a support bracket to form a passage for a stay between the second seal member and the rear molded part in a side portion of the opening. The frame includes a pair of guide walls disposed more inboard than a side edge of the opening and slidably guiding the slider in the fore and aft direction and a vertical wall formed to stand upright at a position more outboard than the side edge of the opening. The support bracket has a U-shaped cross section opened upward and is disposed to receive a flange portion depending from the side edge of the opening.

The present invention achieves a good closing of an opening and closing member, good sealing properties, good sound insulating properties, and good contour following properties.

A weather strip (10) includes a sealing section (12) having a main lip section (15) and a sub lip section (16). A space (S) surrounded by the main lip section (15), the sub lip section (16), a vehicle-interior-side upper wall section (12d), and an opening and closing member (back door 4) is contained within a region (R) between the sealing section (12) and the opening and closing member (back door 4) facing each other.

Seal sections of a weather strip comprise: an upper edge section seal which is in contact with the upper edge section of a door; a side edge section seal which is in contact with a side edge section of the door; and a connecting section seal which connects the upper edge section seal to the side edge section seal. The seal sections comprise first drip channels which are capable of connecting water from the exterior of a vehicle. Second drip channels, which are capable of collecting water that flows along the vehicle exterior sides of the seal sections, are formed between the seal sections and the drip lips. A communication section, which communicates between one first drip channel and one second drip channel, is formed in the connection section seal.

There are provided a pillar attached to a vehicle-body side separately from a roof, a pillar-side weather strip provided at the pillar, a vehicle-body-side weather strip provided at a vehicle-body side of a lower portion of the pillar, and an engagement portion provided at a lower end portion of the pillar-side weather strip, the engagement portion being configured to engage from an inward side, in a vehicle width direction, of the vehicle-body-side weather strip. The vehicle-body-side weather strip comprises a guide portion which guides the engagement portion of the pillar-side weather strip inward and downward, an engaged portion positioned at a lower portion of the guide portion, and a wall portion which contacts a hanging piece provided at the lower end portion of the pillar-side weather strip from an outward side in the vehicle width direction.

There are provided a front weather strip provided between a first roof member and a second roof member, a rear weather strip provided between the second roof member and a third roof member, a roof-side weather strip provided at the second roof member, and a vertical weather strip. Plural partition walls which form the plural vertical flow passages are provided at the vertical weather strip, and a first flow passage for distributing water from the front weather strip to plural vertical flow passages of the vertical weather strip by way of the roof-side weather strip and a second flow passage for distributing water from the rear weather strip to at least one of plural vertical flow passages of the vertical weather strip are provided.
