Abstract

A lightweight and compact muffler device that can be installed in a limited space in an inside of a generator. A top cover and an undercover (end cover) provided on a top and a bottom of a vertically disposed casing are each formed in substantially trapezoidal shape. Thereby, an inner capacity of the casing can be secured to be large, as a result of which, a size of the muffler device can be made compact, and no extra component is required, so that reduction in manufacturing cost and reduction in weight can be achieved. Since the casing is disposed vertically, it is possible to install the casing even when an installation space is small in an inside of a housing of a generator, and it is possible to make the generator compact.
