Claims

[Scope of Claim for Utility Model Registration] 1. A vibration isolating device interposed between the mounting leg of a marine main engine and the floor of the mounting base, which includes a plurality of vibration isolating rubber devices that mainly share the load in the vertical direction, and mainly a propeller. 1. A vibration isolator for a marine main engine, comprising a plurality of thrust receivers each having thin steel plates provided parallel to a propeller shaft so as to share axial loads as tensile loads. 2 A plurality of thrust receiving devices are attached to a first mounting fixture fixed to the lower surface of the mounting leg of the main engine, and a second mounting fixture fixed to the upper surface of the mounting base parallel to the propeller axis with a space between them. and one or more steel plates with both ends pivotally connected to the two fittings, and the first and second steel plates are arranged in parallel oppositely in the direction of the propeller axis. 2. A vibration isolator for a main engine of a ship according to claim 1, wherein a pair of thrust receiving devices each having a steel plate installed on two fittings are arranged near a vibration isolating rubber device.
