PROBLEM TO BE SOLVED: To provide a grommet capable of holding a linear member, even if the linear member is inclined to an axial direction of a grommet.SOLUTION: When an attaching cylinder portion 48 coupled to one end portion in an axial direction of a body cylinder portion 46 of a grommet 32 is inserted in an opening 42 of an upper frame 20, an engaging claw 60 formed on an outer periphery of the attaching cylinder portion 48 is engaged with a peripheral edge portion of the opening portion 42 by elastic deformation, and the grommet 32 can be attached to the upper frame 20. When a seat back spring 30 is inserted in the grommet 32, a holding portion 50 formed on an inner peripheral portion of a boundary between the body cylinder portion 46 and the attaching cylinder portion 48 holds the seat back spring 30. An inner diameter R1 of the holding portion 50 is smaller than an inner diameter R2 of the body cylinder portion 46 and an inner diameter R3 of the attaching cylinder portion 48. Both of an inner peripheral surface 46B of the body cylinder portion 46 and an inner peripheral surface 48B of the attaching cylinder portion 48 are formed in mortar-shapes decreasing diameters toward the holding portion 50.SELECTED DRAWING: Figure 1 |
