Title:
VIBRATION PROOF MEMBER
Document Type and Number:
Japanese Patent JP2014228126
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration proof member which attenuates vibration transmitted among a plurality of members.SOLUTION: A grommet 50 provided between a frame 3 of a vehicle and a fitting part 28 of a tank seal valve comprises a through-hole forming part 51 and a contact part 52. The through-hole forming part 51 has a through-hole 511 in which a bolt 55 and a collar 57 are inserted in the center in an axial direction. The contact part 52 is formed in the way that it projects from an inner wall of the through-hole forming part 51 in a radially inward direction and, when the collar 57 and the bolt 55 are inserted in the through-hole 511, a part of an outer wall 574 outside in a radial direction of the collar 57 comes into contact with an inner wall 521 inside in the radial direction of the contact part 52, and a gap 53 is formed between the inner wall of the through-hole forming part 51 and the outer wall 574 of the collar 57. Thus, when the grommet 50 is elastically deformed by a fastening force of the bolt 55, the grommet 50 can be deformed by using the gap 53, so that the degree of decrease in elasticity of the grommet 50 can be reduced.
