Title:
OUTBOARD MOTOR VIBRATION-ISOLATING SUPPORT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2001/021481
Kind Code:
A1
Abstract:
A center frame (64) fixed to the lower end of the swivel shaft (62) of an outboard motor by bolts (79) includes a swivel shaft extension (64¿1?) extending downward from the lower end of the swivel shaft (62), and cores (64¿2?) extending transversely from the lower end thereof and each having a lower mount rubber piece (80) integrally baked thereon, the lower mount rubber pieces (80) being restrained by the rear surface of an extension case (42). This makes it possible to increase the spacing between the upper mount rubber piece installed on the upper portion of the swivel shaft (62) and the lower mount rubber pieces (80) installed on the lower portion of the swivel shaft (62) without downwardly extending the swivel shaft (62) itself and to enhance the vibration-isolating effect while avoiding an extra increase in weight and cost.
