本发明提供防振装置和防振发动机。防振装置(20)包括:螺旋弹簧(24)、第1倾斜部(21)和第2倾斜部(22)。螺旋弹簧(24)配置在船舶的船身(2)和推进用发动机(4)之间,用于吸收推进用发动机(4)的振动。第1倾斜部(21)具有与纵倾角对应的第1倾斜面(21a),且配置在船身(2)和螺旋弹簧(24)之间,使螺旋弹簧(24)的船身(2)那一侧的安装面以接近水平面的方式相对于船身(2)倾斜。第2倾斜部(22)具有与纵倾角对应的第2倾斜面(22a),且配置在推进用发动机(4)和螺旋弹簧(24)之间,使螺旋弹簧(24)的推进用发动机(4)那一侧的安装面以接近水平面的方式相对于推进用发动机(4)倾斜。

    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.
