    • [Objective] To provide a gas sensor in which a filter member provided in an aerial communication hole adapted to introduce the air for exposing a reference electrode of a detection element to the air is reliably protected through simple configuration.[Means for Solution] A filter member 87 having air permeability and waterproofness is disposed in an aerial communication hole 91 formed in a grommet 9 disposed in a rear end portion 38 of a housing tube 3. The housing tube 3 has a vent portion 34 provided for ensuring aerial communication while protecting the filter member 87. The vent portion 34 is connected, by means of arm portions 33, to an end portion (an opening end 32) of a side wall 39 of the housing tube 3. The side wall 39 surrounds the circumference of the grommet 9. Since the arm portions 33 are disposed in respective grooves 93 of the grommet 9, the grommet 9 is positioned relative to the housing tube 3. Thus, the vent portion 34 formed integral with the housing tube 3 is free from offset, inclination, torsion, etc., relative to the aerial communication hole 91.
    • [目的]提供一种气体传感器,其中设置在适于将用于将检测元件的参考电极暴露于空气的空气的空气连通孔中的过滤构件通过简单的构造被可靠地保护。 [解决方案]具有透气性和防水性的过滤构件87设置在形成在设置在容纳管3的后端部38中的护环9中的空中连通孔91中。容纳管3具有通气部34, 用于在保护过滤构件87的同时确保空中连通。通气部分34通过臂部分33连接到壳体管3的侧壁39的端部(开口端32)。侧壁39 围绕护环9的周围。由于臂部33设置在护环9的各个槽93中,因此,护环9相对于容纳管3定位。因此,与容纳管3一体形成的排气部34为 没有相对于空中连通孔91的偏移,倾斜,扭转等。
