HÉLICE D'UN APPAREIL DE PROPULSION DE NAVIRE ET APPAREIL DE PROPULSION DE NAVIRE COMPRENANT CELLE-CI

摘要

A propeller (11) for a vessel propulsion apparatus (1) to be attached to a propeller shaft (10) extending in a front-rear direction of a vessel, the propeller (11) comprising: a bushing (31) configured to rotate together with the propeller shaft (10), the bushing (31) including a first cylindrical portion (40) surrounding the propeller shaft (10), and a first protrusion (41) protruding outward from the first cylindrical portion (40) that is integral with the first cylindrical portion (40); a propeller damper (32) made of an elastic material and disposed around the bushing (31); and an inner cylinder (25) including a second cylindrical portion (35) surrounding the bushing (31) via the propeller damper (32), and a second protrusion (36) protruding inward from the second cylindrical portion (35), the inner cylinder (25, 225) being configured to rotate with respect to the bushing (31) between a noncontact position, in which the first protrusion (41) and the second protrusion (36) are separated from each other in a circumferential direction (Dc), and a contact position, in which the first protrusion (41) and the second protrusion (36) come into contact with each other according to elastic deformation of the propeller damper (32).
