One embodiment of the present disclosure provides a grommet capable of suppressing a reduction in waterstop performance while suppressing an increase in size. A grommet (20) according to one embodiment of the present disclosure is provided with: an annular mounting part (21) fixed to a peripheral portion of an insertion hole (12) in a vehicle body panel (11); and a cylindrical stress absorbing section (22) having a cylindrical side wall (41) extending from the inner peripheral edge of the attachment section (21) to one side in the axial direction (X1), and a bottom wall (42) that partially closes the cylindrical side wall (41) at the tip of the cylindrical side wall (41). The grommet (20) is further provided with cylindrical insertion sections (23, 24) which are provided integrally with the bottom wall (42) and which cover the outer peripheries of the wire harnesses (13, 14) inserted into the insertion holes (12). The attachment section (21) has an annular seal section (31) that is in close contact with the peripheral portion of the insertion hole (12) in the vehicle body panel (11). The side wall (41) has flexibility. The insertion sections (23, 24) protrude from the bottom wall (42) toward the base end side of the side wall (41) on the inside of the stress absorbing section (22).

    本公开的一方式提供一种能抑制大型化并且抑制止水性能的降低的护线套。按照本公开的一方式的护线套(20)具备:环形的安装部(21),固定于车身面板(11)中的插通孔(12)的周围部分;和筒状的应力吸收部(22),具有从安装部(21)的内周缘部向轴方向(X1)的一方侧延伸的筒状的侧壁(41)、及在筒状的侧壁(41)的顶端将筒状的侧壁(41)局部地封闭的底壁(42)。护线套(20)进一步具备筒状的插通部(23、24),插通部(23、24)与底壁(42)设置成一体,并且将插通于插通孔(12)的线束(13、14)的外周覆盖。安装部(21)具有与车身面板(11)中的插通孔(12)的周围部分紧密贴合的环形的密封部(31)。侧壁(41)具有可挠性。插通部(23、24)在应力吸收部(22)的内侧从底壁(42)朝向侧壁(41)的基端侧的突出。
