Abstract:
1. A structure for mounting an object on a mounting base, comprising: a bolt having a male screw to be fastened to a female screw formed in the mounting base and a rod portion; a first resilient member disposed between the object and the bolt at a bottom portion of the object; and a second resilient member having a hole into which the rod portion of the bolt is inserted, the second resilient member being disposed between the object and the bolt at an upper portion of the object to suppress vibration propagation between the object and the bolt, wherein: depressions and projections are formed on an inner surface of the hole of the second resilient member to reduce an area contacting the rod portion to thereby reduce abrasion force generated between the hole and the rod portion when the bolt is rotated to be fastened to the mounting base; and an inner diameter of the hole of the second resilient member is smaller than an outer diameter of the rod portion so that the grommet is compressed in the radial direction of the hole when the rod portion is inserted into the hole.
