要請を満足することができない。However, in the above-mentioned conventional weather strip 1, although the sealing property of the vehicle body opening edge is obtained by the seal lips 5 and 6 and the holding lips 9 and 10, the window glass 11 is simply attached to the lower surface 4b of the upper piece 4 of the main body 3. Since the contact is made only from the substantially vertical direction, the requirement for the flash surface cannot be satisfied.
そこで、例えば実開昭５９−９８０７６号公報に記載さ

る。Therefore, for example, as in the device disclosed in Japanese Utility Model Laid-Open No. 59-98076, metal guide members are provided on the inner and outer surfaces of a holding piece that rises inward at the lower end of one sidewall of the weatherstrip body on the vehicle interior side. There is also provided a structure in which the upper end portion of the window glass is guided by the guide member in the vehicle exterior direction along the shape of the guide member.
しかし、この考案は、ガイド部材を剛性の高い金属材で
形成してあるため、閉窓時におけるウィンドガラスの上
端部とガイド部材等との摺動抵抗が大きくなり、ウィン
ドガラスのスムーズな上昇及び車外側への移動が阻害さ
れてしまう。However, in this invention, since the guide member is formed of a metal material having high rigidity, the sliding resistance between the upper end portion of the window glass and the guide member and the like at the time of closing the window becomes large, and the smooth movement of the window glass is prevented. Movement to the outside of the car is hindered.
しかも、ウェザーストリップとは別個のガイド部材を用
いているため、部品点数が増加して製造作業能率の低下
と製造コストの高騰が余儀なくされている。Moreover, since a guide member separate from the weather strip is used, the number of parts is increased, and the manufacturing work efficiency is lowered and the manufacturing cost is inevitably increased.

特徴としている。Means for Solving the Problems The present invention has been devised in view of the above-mentioned conventional problems, and includes a main body held by a window frame of a vehicle body and an upper surface of an upper piece of the main body. In a weather strip having a seal lip that abuts a bottom surface of a window frame, a bent lip vertically provided on the lower surface of the upper piece of the main body has a thin fixed end portion fixed to the vehicle inner side of the lower surface of the upper piece. A base portion that is vertically inclined downward from the fixed end portion toward the outer side of the vehicle, and a bottom edge edge of the base portion that is bent upward to the outer side of the vehicle so as to be inclined so that the edge of the window glass abuts when the window is closed. It is characterized by having a tip part.
作用 本発明によれば、閉窓時に本体内部に下方向から進入し
たウィンドガラスがその上端部で折曲リップの先端部下
面を押圧すると、該折曲リップ全体が薄肉な固定端部を
中心に車外側へ屈曲変形すると共に、先端部も車外側の
上方へ立ち上がる形で屈曲変形する。このため、ウィン
ドガラスの上端部は、折曲リップの先端部下面に摺接し
ながら折曲リップ全体の弾性反力で車外側へ押し出され
て窓枠の外端面側に移動する。Effect According to the present invention, when the window glass that has entered the inside of the main body from below when the window is closed presses the lower surface of the tip of the bent lip at its upper end, the entire bent lip is centered on the thin fixed end. In addition to bending and deforming to the outside of the vehicle, the tip also bends and deforms so as to rise upward outside the vehicle. Therefore, the upper end of the window glass is pushed out of the vehicle by the elastic reaction force of the entire bending lip while slidingly contacting the lower surface of the tip of the bending lip, and moves to the outer end surface side of the window frame.
特に、固定端部が薄肉に形成されているため、折曲リッ
プ全体の車外側への屈曲作用が良好となり、これによっ
て、先端部とウィンドガラス上端部との摺動抵抗が小さ
くなる。In particular, since the fixed end portion is formed thin, the bending action of the entire bent lip toward the outside of the vehicle is improved, and thus the sliding resistance between the tip end portion and the upper end portion of the windshield is reduced.
また、ウィンドガラスが最上昇位置に達すると、本体上
片のシールリップが窓枠の下面に圧接して窓枠と本体と
の間を確実にシールすることができる。Further, when the window glass reaches the highest position, the seal lip of the upper piece of the main body is brought into pressure contact with the lower surface of the window frame to reliably seal the space between the window frame and the main body.
