The present invention reduces the generation of an unusual sound resulting from vibration of a part of a sheet. A first sheet includes: a peripheral portion which is to surround a service hole of a door inner panel; and a central portion surrounded by the peripheral portion, the first sheet having, along a boundary between the central portion and the peripheral portion, a plurality of first holes and a plurality of second holes each of which differs in size from each of the plurality of first holes.

Sheet, door hole seal, and method for producing the same

Noise caused by vibration of a door hole seal is reduced. A door hole seal includes a first sheet having a slit formed therein and a second sheet covering the slit from an exterior side of a vehicle. At least a specific region of the second sheet is made of a rubber-like elastic body, the specific region extending from a portion corresponding to the slit to a vertically lower end of the second sheet.

Door hole seal

A method for evaluating noise of a glass run of an automobile door includes: detecting oscillation of the door glass by a sensor for the door glass and then storing the oscillation as an oscillatory wave form of the door glass and detecting oscillation of the frame by a sensor for the frame and then storing the oscillation as an oscillatory wave form of the frame, with the glass run coupling to the automobile door; synthesizing the oscillatory wave form of the door glass and the oscillatory wave form of the frame, picking out relative oscillation of the door glass in relation to the frame and storing the relative oscillation as a synthesized oscillatory wave form; making oscillation corresponding to the synthesized oscillatory wave form by an oscillator and oscillating the door glass with the automobile stopped; and detecting sound of the oscillation by a microphone.

Method for evaluating noise of glass run

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.

Seal structure of automotive vehicle with storing-type roof

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.

Vehicle-body structure of automotive vehicle with storing-type roof

There is provided a mounting structure of a weather strip comprising a weather stripmounted on a door panelA or a body panelB of an automobile. The weather stripcomprises a fin portionformed in a die molded partof the weather stripto cover existing holesor mounting holesformed in the panelan insert platemounted in the fin portiona locking projectionprotrudely formed from the insert plateand projects out of the fin portionand an engagement memberattached to the locking projectioncapable of disconnecting. The engagement memberis inserted into a existing holeor an mounting holeformed in the panelfor an engagement and to mount the weather stripon the panel

Mounting structure of weather strip

A weather strip includes an attachment base ( ) and a hollow seal portion ( ). The hollow seal portion ( ) is integrally moulded with the outer wall ( ) of the attachment base ( ), and it makes a resilient contact with the door ( ) when the door ( ) of a vehicle is closed. The hollow seal portion ( ) has a first wall ( ), second wall ( ), third wall ( ), fourth wall ( ) and bridge ( ). The bridge ( ) is spanned between the second wall ( ) and the fourth wall ( ). The hollow seal portion ( ) includes bending points which bend when the door ( ) is closed. The bending points include a connection part ( ) formed between the second wall ( ) and the third wall ( ), a connection part ( ) formed between the third wall ( ) and the fourth wall ( ), and a connection part ( ) formed between the first wall ( ) and the fourth wall ( ).
