Description

The present invention
The present invention relates to a cowl top garnish that is disposed between a front hood and a windshield of a vehicle and has a contact edge on the rear end side in contact with the front surface of the lower end of the windshield.

  A vehicle such as an automobile is provided with a cowl box above the dash panel, which serves as an intake port for outside air into the vehicle and in which a wiper drive mechanism is disposed. The cowl top garnish is arranged at the upper part of the cowl box so as to decorate between the rear end of the front hood and the front end (lower end) of the windshield and cover the upper part of the cowl box.

  The cowl top garnish is a resin molded product having an air inlet, and has a structure that prevents foreign matters such as snow, leaves, and dust from entering the vehicle when introducing outside air into the vehicle. When such a cowl top garnish is assembled to the vehicle body, it looks bad if there is a gap between the rear end of the cowl top garnish and the lower end (front end) of the windshield. Therefore, a structure for eliminating the gap has been devised.

  As an example, a clip or the like is attached to the back side near the rear end of the cowl top garnish, and the rear end of the cowl top garnish is firmly pressed against the lower end of the windshield by fixing the vicinity of the rear end to the vehicle body. There was one technology. However, in the first technique, there is a problem that the gap between the fixing point of the vehicle body and the windshield is misaligned or is too strongly contacted. When the number of clips is small, the pressing force becomes uneven, and it is difficult to eliminate the gap over the entire width of the cowl top garnish.

  In order to solve this problem, as disclosed in Patent Document 1, a second technique has been proposed in which a separate soft molding is attached to the rear end of the cowl top garnish. However, in the second technique, there is a problem that a separate molding is required, the number of components increases, and it takes time to attach the molding to the rear end.

On the other hand, as disclosed in Patent Document 2, on the back side of the rear end portion of the cowl top garnish, a plurality of L-shaped cross sections that form a U-shaped sandwiching groove together with the rear end portion are formed. There is a third technique in which sandwiching pieces are integrally formed at regular intervals in the vehicle width direction, and the lower end portion of the windshield is elastically sandwiched by the sandwiching grooves. In this technique, the width of the clamping groove is formed to be narrower than the thickness of the lower end portion of the windshield so as to ensure a sealing property between the rear end portion of the cowl top garnish and the lower end portion of the windshield.
JP-A-8-119145 JP-A-5-97060

According to the third technique, although the gap can be easily eliminated without increasing the number of parts,
(1) The holding groove must be lifted from the front lower side of the lower end of the windshield to the rear upper side along the windshield, and the lower end of the windshield must be inserted and fitted into the holding groove,
(2) Since the width of the holding groove is narrower than the thickness of the lower end portion of the windshield, it is difficult to fit the lower end portion of the windshield into the holding groove.
It took time to assemble the holding groove to the windshield, leaving room for improvement in terms of assembly.
