As described above, in the tilt-type sunroof 10 according to the present embodiment, the mountain-shaped projection 15t is integrally formed on the upper surface of the resin molding 15 at the center of the rear end of the tilt-type sunroof glass 14. The airflow along the upper surface of the tilt-type sunroof glass 14 is disturbed by the protrusion 15t at the rear end of the tilt-type sunroof glass 14. For this reason, even if the tilt type sunroof 10 is opened by a predetermined amount, the airflow is disturbed by the projection 15t, so that a periodic vortex is not generated behind the tilt type sunroof 10. Therefore, the tilt type sunroof 10
With the specified amount open, the rear sliding sunroof 20
When you open the window, almost no windslob occurs. In the case of the conventional tilt-type sunroof, a windslob occurred at a traveling speed of about 60 km / h, but in the case of the tilt-type sunroof 10, no windslob occurred even when the traveling speed exceeded 100 km / h. .

Therefore, the tilt-up amount of the tilt-type sunroof 10 can be increased, and the original function of the tilt-type sunroof can be sufficiently exhibited. Also,
As in the prior art, it is not necessary to increase the height of the deflector provided at the front end of the opening of the rear sliding sunroof 20 to disturb the vortex generated behind the tilting sunroof 10, so that the height of the deflector is reduced. It is possible to suppress wind noise. In addition, the protrusion 15t
Is integrally formed with the resin molding 15 integrally formed with the tilt-type sunroof glass 14, so that it is possible to take measures against wind slop with almost no increase in cost.
Here, in the tilt type sunroof 10 according to the present embodiment, an example is described in which only one protrusion 15t is formed at the center of the upper surface of the resin molding 15 at the rear end of the tilt type sunroof glass 14, but the present invention is limited to this. However, it is also possible to form a plurality. Further, the protrusion 15t is arranged at the center in the width direction of the resin molding 15, but is not particularly limited to the center.

[Second Embodiment] Next, a tilt sunroof for a vehicle according to a second embodiment of the present invention will be described with reference to FIG. In the tilt sunroof 30 for a vehicle according to the present embodiment, a protrusion 28t that disturbs the flow of airflow along the tilt-type sunroof glass 14 is provided to a retainer 28n for fixing the handle 28 to the tilt-type sunroof glass 14.
The other structure is the same as that of the tilt sunroof 10 for a vehicle according to the first embodiment. The protrusion 28t is formed in an outer shape substantially equal to the protrusion 15t according to the first embodiment.

A nut is projected from the lower surface of the retainer 28n, and a grommet 28b is mounted around the nut. The grommet 28b includes a cylindrical portion 28e fitted into the through hole 24k of the tilt-type sunroof glass 14 and a flange portion 28f abutting on the upper surface of the tilt-type sunroof glass 14. The flange portion 28f has a retainer 28n. Is housed in a ring-shaped recess 28p formed on the lower surface of the. by this,
The retainer 28n and the projection 28t come into surface contact with the upper surface of the tilt-type sunroof glass 14 without fail.

A spacer 28s is in surface contact with the lower surface (inside of the vehicle) of the tilt-type sunroof glass 14 from the opposite side of the retainer 28n, and the handle 28 is connected to the bolt 28y and the retainer 2 via the spacer 28s.
8n, it is fastened to the tilt type sunroof glass 14. That is, the tilt-type sunroof glass 14 is sandwiched from above and below by the retainer 28n, the spacer 28s, and the handle 28, and the handle 28 is indirectly fixed to the tilt-type sunroof glass 14. The handle 28 has the same structure as the handle 18 according to the first embodiment.
The tilt type sunroof glass 14 can be held in a locked state by engaging the engaging claw 28k of No. 8 with the lock member 19r. The locked state can be released by pressing a knob (not shown) of the handle 28.

As described above, in the tilt type sunroof 30 according to the present embodiment, similarly to the first embodiment, a mountain-shaped projection 28 is formed at the center of the rear end of the tilt type sun roof glass 14.
Since t is formed, the operation of the projection 28t suppresses the occurrence of the wind throb. Further, since the projection 28t is formed integrally with a retainer 28n for fixing the handle 28 to the tilt-type sunroof glass 14, a windslob countermeasure can be taken with almost no increase in cost.

[0019]

According to the present invention, at the rear end of the tilt-type sunroof, a molding formed integrally with the periphery of the tilt-type sunroof glass or a retainer for fixing the handle for opening and closing the tilt-type sunroof glass are formed integrally. Since the occurrence of windslob can be suppressed by the projections, the tilt-up amount of the tilt-type sunroof can be increased, and the height of the deflector provided at the front end of the opening of the rear slide-type sunroof can be reduced. . Therefore, the riding comfort of the vehicle is improved. In addition, since the protrusion is formed integrally with the molding or the retainer, it is possible to take measures against a wind throb with almost no increase in cost.
