Cylindrical mounting apparatus equipped with bracket

A cylindrical mounting apparatus equipped with a bracket comprising:

• a cylindrical mount including an inner and outer sleeve disposed in mutually spaced-apart relation with each other, and an elastic body interposed between said inner and outer sleeves so as to elastically connect said inner and outer sleeves;
• a bracket independent of said cylindrical mount, having a pair of support plates opposed to each other with a spacing therebetween, and assembled with said cylindrical mount such that said cylindrical mount is inserted into said spacing between said pair of support plates and fasten to said bracket by means of a mounting bolt extending through a bore of said inner sleeve across said pair of support plates;
• two positioning protrusions formed on and protruding from at least one of said pair of support plates toward an other of said pair of support plate;
• a mounting plate disposed on one of axially opposite end portions of said inner sleeve so as to extend in a direction orthogonal to an axial direction of said inner sleeve, said mounting plate being held in contact with an inside surface of said at least one of said pair of support plates, and having an engaging portion of recessed shape, which is open in an outer circumferential surface of said mounting plate, and which is brought into abutting contact with said two positioning protrusions so as to place said mounting plate in a predetermined position about a center axis of said inner sleeve on said inside surface of said at least one of said pair of support plates,
• wherein said engaging portion comprises a cutout portion formed at a peripheral portion of said mounting plate, extending circumferentially with a circumferential length not larger than a half of a circumference of said mounting plate, and circumferentially opposite end portions of said cutout portion are brought into engagement with said two positioning protrusions of said at least one of said pair of support plates, respectively, and
• a plate-form member independent of said cylindrical mount and said bracket, said plate-form member being superposed on said mounting plate, sandwiched between and supported by said mounting plate and said at least one of said pair of support plates, and having an engaging jaw brought into engagement with a circumferentially intermediate portion of said cutout portion of said mounting plate.
