  • Patent number: 10569725
    Abstract: A grommet which can maintain water tightness in response to inclination is provided. In an attachment section of the grommet, a substantially right-angled first bending portion is formed between a first flange portion and a tubular portion. Thus, when the attachment section is inclined with respect to a panel member, the first bending portion changes in angle, thereby absorbing the inclination, and thereby maintaining the contact between the annular lip portion and a planar portion. As a result, water tightness can be maintained in response to the inclination.

  • Patent number: 10562471
    Abstract: A grommet which can prevent unintended deformation of an annular lip portion is provided. The annular lip portion is configured to be compressed in a compression direction corresponding to a direction perpendicular to a plane of a panel member. Thus, even if the annular lip portion is formed with a large length to ensure a pushing force against a planar portion, a tip edge of the annular lip portion is unlikely to be located in the vicinity of a first flange portion. Therefore, the annular lip portion is avoided from contacting the other members, preventing unintended deformation of the annular lip portion.

  • Patent number: 10518723
    Abstract: A grommet which allows an annular lip portion to be pushed hardly against a panel member is provided. When the annular lip portion abuts on a planar portion on a radially inner side than an outer peripheral edge of a flange portion, a protruding portion of the annular lip portion is sandwiched between the planar portion and the flange portion. An inner member of a grommet is made of a material having a higher degree of hardness than the material of a body of the grommet, thereby allowing the annular lip portion to be pushed hardly against the panel member.

  • Patent number: 10293764
    Abstract: A resin molded body (10) includes a metal attachment member (22) and an extension part (33, 34) extending from the resin molded body. At least one part of the metal attachment member (22) is exposed in a mounting surface (20a) of the resin molded body. The mounting surface (20a) is to be facing to the mounting target when the resin molded body is fixed to a mounting target. At least one part of the extension part (33, 34) is protruded outside the mounting surface. A protrusion length of the at least one part of the extension part (33, 34) from the mounting surface is larger than a protrusion length of the metal attachment member (22) from the mounting surface. The at least one part is configured to allow deforming in a direction away from the mounting target when the resin molded body is fixed to the mounting target.
