The invention belongs to the technical field of engineering machinery, and discloses a rotation limiting and adjusting mechanism which is used for rotation adjusting and limiting of a rotation component relative to a base and comprises a supporting part, a plug pin and a limiting groove, and the supporting part synchronously rotates along with the rotation component; the plugging pin is arranged on the supporting part in an up-and-down sliding mode, and an adjusting assembly for driving the plugging pin to move up and down is arranged on the supporting part; the limiting groove is formed in the base; the number of the limiting grooves is at least two corresponding to different postures of the rotary component, or/and the number of the plugging pins is at least two corresponding to different postures of the rotary component. And during limiting, at least part of the inserting and pulling pins are inserted into the corresponding limiting grooves in an aligned manner. The invention further discloses the seat for the engineering machinery cab. According to the novel seat adjusting structure, the structural arrangement form can be optimized, the user experience is improved, the structural arrangement is relatively flexible, and the layout can be flexibly adjusted according to the space structure.
