Are formed. The concave portion 52 has, for example, a bottom portion at the center.
A deepest deep groove portion 53 of 54 is formed, a shallow groove portion 55 having a shallow bottom portion 56 and a slope portion 57 is formed around the deep groove portion 53, and a plurality of fixing bolts are fitted into the shallow groove portion 55. A pair of through holes 58, 58 to be inserted are provided.

[0005] The grommet seal portion 61 is formed of an elastic material such as rubber, and an inner 41 such as a metal plate or a synthetic resin plate is integrally insert-molded therein as necessary. The shape of the grommet seal portion 61 is substantially the same as the shape of the shallow groove portion 55 of the concave portion 52 formed on the door frame A, and when the grommet seal portion 61 is fitted in the concave portion 52,
It is formed so as to have the same height as the surface of the door frame A. Further, the grommet seal portion 61 is provided with a through hole 63 for a fixing bolt 59 at a position corresponding to the door frame A through hole 58, and is firmly fixed to the door frame A by the fixing bolt 59.

In addition, a lip-shaped projection 68, for example, is integrally provided on the peripheral end surface of the peripheral portion 67 of the grommet seal portion 61 which comes into contact with the slope 67 around the shallow groove 65 as necessary.
