Description

The present invention relates to a wiping member and a vehicle wiping device, and more particularly to a wiping member and a vehicle wiping device comprising the wiping member.

2. Description of the Related Art Conventionally, in washing vehicles such as automobiles and trains, after washing the vehicle surface with water, the vehicle surface is wiped and dried by an air blower and a vehicle wiping device.

Also, in order to check the water infiltration resistance at the time of manufacture of a vehicle, the vehicle surface is wiped and dried by a vehicle wiping device after the vehicle surface is sprayed with water.

Such a vehicle wiping device is provided with a water-absorbent woven cloth or nonwoven fabric as a wiping member, and the wiping member wipes the vehicle surface by contacting and sliding on the vehicle surface.

On the other hand, if a woven cloth or a nonwoven cloth is used as the wiping member, the adhesion to the vehicle surface is insufficient and the wiping property is poor.

Therefore, for example, a cloth consisting of a thin rectangular plate-shaped curtain, a mounting tube connecting the upper part of the cloth, and a weight such as fishing lead and a yarn-like tuft attached to the lower part of the cloth. A wet wipe has been proposed (see, for example, Patent Document 1 (FIG. 11)).

JP-A-8-253111

However, as described in Patent Document 1, simply attaching the weight and the yarn-like tufts to the lower portion of the cloth body does not provide sufficient adhesion to the surface of the vehicle, resulting in poor wiping performance.

The present invention provides a wiping member with excellent wiping properties, and a vehicle wiping device provided with the wiping member.

The present invention [1] is a wiping member for wiping a vehicle surface by contacting and sliding on the vehicle surface, the rubber sheet having a drape property, and one surface side of the rubber sheet, the vehicle surface. It includes a wiping member with an absorbent cloth provided in contact therewith.

The present invention [2] includes a vehicle wiping device comprising: the wiping member according to [1] above; and a fixing member that fixes the rubber sheet so that the water absorbing cloth of the wiping member is in contact with the surface of the vehicle. I'm in.

The wiping member of the present invention is a wiping member that contacts and slides on a vehicle surface to wipe off the vehicle surface, and includes a rubber sheet having a drape property and one side of the rubber sheet that can contact the vehicle surface. and a water absorbing cloth provided.

In such a wiping member, the water-absorbing cloth adheres to the vehicle surface according to the drape property of the rubber sheet, so the vehicle surface can be wiped off satisfactorily.

Therefore, the vehicle wiping device provided with the wiping member described above has excellent adhesion between the wiping member and the vehicle surface, and can wipe the vehicle surface satisfactorily.
