FILTER ATTACHMENT STRUCTURE FOR POWER SOURCE, AND CONSTRUCTION MACHINE USING THE SAME

摘要

To provide a filter attachment structure for a power source capable of securing a lay-out of a mount part which can suppress vibration transmission of the power source to a vehicle body frame while securing maintainability to a filter for the power source.SOLUTION: A filter attachment structure for a power source is provided with: a power source 61; a mount bracket part 85; an oil pump 63; a post treatment device 71 positioned above the oil pump 63 and fixed on the power source 61 through a post treatment device support member 73 to clean exhaust gas of the power source 61; and a filter 91 for the power source removing impurities from oil circulating in the power source 61. The post treatment device support member 73 is configured to extend beyond the mount part 83 in one direction of a rotational axis 61b, and a filter 91 for the power source is positioned at the one direction of the rotational axis 61b further than the mount part 83 and fixed on the post treatment device support member 73.SELECTED DRAWING: Figure 4
