Title:
防振装置及び防振エンジン
Document Type and Number:
Japanese Patent JP6599389
Kind Code:
B2
Abstract:
A vibration isolator (20) includes coil springs (24), a first inclination part (21), and a second inclination part (22). The coil springs (24) are disposed between a hull (2) of a ship and a propulsive engine (4) and absorbs vibration of the propulsive engine (4). The first inclination part (21) has a first inclined surface (21a) corresponding to a rake angle and is disposed between the hull (2) and the coil springs (24), the first inclination part (21) causing an attachment surface for the coil springs (24) on the side close to the hull (2) to be inclined with respect to the hull (2) so that the attachment surface approximates a horizontal plane. The second inclination part (22) has a second inclined surface (22a) corresponding to the rake angle and is disposed between the propulsive engine (4) and the coil springs (24), the second inclination part (22) causing an attachment surface for the coil springs (24) on the side close to the propulsive engine (4) to be inclined with respect to the propulsive engine (4) so that the attachment surface approximates a horizontal plane.
