The invention discloses a motor train unit body and an inner windshield mounting structure thereof. The inner windshield mounting structure is used for mounting an inner windshield at the end part of the motor train unit body, and comprises a bottom plate bolt, a bottom plate nut and a bolt sleeve, wherein the bolt sleeve penetrates through an end bottom plate of the motor train unit body, and is fixedly arranged on the end bottom plate of the motor train unit body, the bottom plate bolt is inserted into the bolt sleeve, and penetrates through the end bottom plate and an inner windshield transition plate of the inner windshield, and an outer thread section of the bottom plate bolt is matched with the bottom plate nut to realize locking. The inner windshield mounting structure has the advantages that the inner windshield and the end bottom plate of the motor train unit body are fixed by the bottom plate bolt; compared with a welding fixing method, the welding deformation can be avoided by the connecting method, the connecting is firm, and the detachment is convenient; the bolt sleeve is used as a mounting seat, and is arranged in a cavity of the end bottom plate, so the arrangement of a special mounting seat is not needed, and the space is saved; the bolt sleeve is arranged in the cavity of the end bottom plate, so the strength of the mounting position of the end bottom plate is enhanced, and the deformation of the end bottom plate caused by the pressing of the end bottom plate because of tightening of the bottom plate bolt is avoided.
