these sides the three sides 37 to 39 are continuous but the other side 41 is severed in the middle by means of this severed portion side 41 can be opened out wider than axial part 33 enabling anti vibration member 5 to be mounted on axial part 33 of securing part 3 in a simple manner such as to surround it on anti vibration member 5 as shown in fig1 on the outside portions of sides 37 to 39 there are formed grooves 42 that fit slidably on to guides 22 and guide frame element 23 of base 12 of pipe holding part 2 a groove 42 is also formed on side 41 so that withdrawal preventing claws 25 that extend from guides 22 can fit into this groove 42 thus anti vibration member 5 is connected to base 12 by guides 22 and guide frame element 23 by means of these grooves 42 since anti vibration member 5 is mounted so as to surround the outer peripheral surface of axial part 33 of securing part 3 anti vibration member 5 performs the function of mounting securing part 3 on base 12 of pipe holding part 2 the size and shape of anti vibration member 5 are determined by securing member 3 and base 12 but alteration of the shape may be performed to match for example the anti vibration characteristic for example the frequencies etc of vibration that are to be.
