PROBLEM TO BE SOLVED: To effectively prevent generation of suctioning sound in a vehicular door D.SOLUTION: There is provided a motorcar door fixing apparatus comprising: a sucker 20 arranged on either of a door opening part 10 of a vehicle body A or a door arranged on the door opening part; an adhesion target surface which is arranged on the other one of the door opening part or the door and which contacts to the sucker in a situation where the door is closed; a suction port 21 arranged on either of the sucker or the adhesion target surface; negative pressure generating means, such as a brake booster 26, which is communicated with the suction port to apply negative pressure. A switch valve 25 is arranged between the suction port and the negative pressure generating means. In a case where the vehicular speed reaches a predetermined level or more, the switch valve applies negative pressure provided by the negative pressure generating means to the suction port, and in a case where the vehicular speed is less than the predetermined level, the suction port is exposed to the air. At that time, after several seconds from the application of negative pressure to the suction port, the application is stopped. In a case where the door is a side door, the sucker and the suction port are arranged on a door opening part of the vehicle body or on an upper part at a vehicular rear side of the side door.SELECTED DRAWING: Figure 1

    【課題】車体ドアDにおける吸出し音の発生を安価にして有効に防止する。【解決手段】車体Aのドア開口部10又は前記ドア開口部に設けたドアの一方に設けた吸盤20と、前記ドア開口部又は前記ドアの他方に設け、前記ドアが閉じた状態で、前記吸盤と当接する被吸着面と、前記吸盤又は前記被吸着面の一方に設けた吸気口21と、前記吸気口に連通して負圧を印加させるブレーキ倍力装置26等の負圧生成手段と、を有する自動車用ドア固定装置である。前記吸気口と前記負圧生成手段との間に切替弁25を介設し、前記切替弁により、車体速度が一定以上になった時、前記負圧生成手段による負圧を前記吸気口に印加し、前記車体速度が一定未満の時には、前記吸気口を大気に開放する。そのとき、前記吸気口へ負圧を印加した数秒後、その印加は止める。前記ドアがサイドドアの場合、前記吸盤及び前記吸気口は、前記車体のドア開口部もしくは前記サイドドアの車体後側の上部に設ける。【選択図】図1
