To allow a fire grate to be mounted and replaced from a portion above the fire grate and inside a stoker-type incinerator, and to surely prevent the fire grate from floating more than necessary while ensuring flexibility in upward displacement of the fire grate.
In this mounting structure of the fire grate of the stoker-type incinerator, a holding section 82 for holding a rear end of the fire grate 6, is disposed on a fire grate receiving beam 8 for loading and supporting the fire grate 6, a shaft pin 66 is disposed at a lower side of the fire grate 6, an engagement recessed section 83 is disposed on the fire grate receiving beam 8, and the shaft pin 66 and the engagement recessed section 83 are disposed to be engaged with each other when the fire grate 6 is displaced upward, to control the upward displacement of the fire grate 6 by the engagement of the shaft pin 66 and the engagement recessed section 83.
