Document Type and Number:
Japanese Patent JP2015224594
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an exhaust static tube support structure capable of increasing a natural frequency and suppressing an increase in bending moment transmitted to an attachment portion as much as possible.SOLUTION: An exhaust static tube support structure comprises: a flexural plate 32 provided between an exhaust static tube 14 and a scavenging trunk 20, and including plates 32a and 32b supporting the exhaust static tube 14 from below, the plates 32a and 32b being disposed to be orthogonal to a longitudinal direction of the exhaust static tube 14; an upper attachment plate 40 fixed to the exhaust static tube 14 and connected to an upper end portion of the flexural plate 32; and a lower attachment plate 43 fixed to the scavenging trunk 20 and connected to a lower end portion of the flexural plate 32, the flexural plate 32 including a pair of facing plates 32a connected to each other with the upper attachment plate 40 and the lower attachment plate 43 held therebetween, and the adjacent plate 32b provided to be adjacent to one of the facing plates 32a.
