Claims

1. A construction for securing a trim strip for an automotive door, the construction including:

a door flange provided to a window frame of the automotive door to protrude toward an outside of a compartment of a car; and

the trim strip secured to the door flange from the outside of the compartment, the construction comprising;

an outer protrusion formed on an end, of the door flange, close to the outside of the compartment, the outer protrusion protruding upward;

an upper step formed on a portion, of an upper face of the door flange, closer to a base end of the door flange than the end on which the outer protrusion is formed, the upper step positioning the upper face of the door flange higher to the outside of the compartment than to an inside of the compartment;

an exterior appearance portion facing the outside of the compartment and creating an appearance;

a fit portion, provided to an upper portion of the exterior appearance portion, into which the outer protrusion is inserted and fits;

an engagement portion extending from the fit portion to the upper step, and engaging with the upper step from above; and

a lower abutting portion extending from a portion, of the exterior appearance portion, below the fit portion, and abutting to a lower face of the door flange from below,

wherein the trim strip includes the exterior appearance portion, the fit portion, the engagement portion, and the lower abutting portion.

2. The construction of claim 1, further comprising:

a lower step provided to the lower face of the door flange, the lower step being formed to position the lower face of the door flange higher to the outside of the compartment than to the inside of the compartment,

wherein the lower abutting portion of the trim strip abuts to the lower step from the outside of the compartment.

3. The construction of claim 1, further comprising a sealing protrusion provided to an interior surface of the fit portion of the trim strip, the sealing protrusion making contact with the door flange and sealing a gap between the interior surface and the door flange.

4. The construction of claim 3, wherein the engagement portion of the trim strip is made of a hard resin material harder than the sealing protrusion.

5. The construction of claim 1, further comprising a glass run secured to the trim strip, so that a circumferential edge of the window glass, disposed to freely rise and fall in the window frame, makes contact with the glass run.

6. The construction of claim 1, further comprising an introduction opening formed between the engagement portion and the lower abutting portion of the trim strip, the introduction opening introducing the outer protrusion of the door flange into the fit portion.
