A manual window regulator device comprising:

• a drum;
• handle shafts provided at opposing sides of an inner portion of the drum, each handle shaft including a catching part protruding from an inner side thereof;
• a glass shaft rotatably provided substantially at the center of the drum and engaged to the catching parts of the handle shafts while being caught by the catching parts at the time of a left or right turn;
• and
• at least a roller part provided on the drum, and engaging the handle shafts and the glass shaft together while being fitted between the handle shafts and the drum at the time of rotation of the handle shafts at one of the first or right turn so as to rotate the at least a roller part, the handle shaft and glass shaft simultaneously,
• wherein the catching parts are protrudedly formed substantially at the center of the inner side of the handle shafts,
• wherein the glass shaft includes protrusion parts formed at both distal end portions thereof, respectively, so as to be selectively engaged by the catching parts, and
• wherein when a glass is manipulated, the glass shaft is rotated, thereby supporting the protrusion parts of the glass shaft by one end of the catching parts of the corresponding handle shaft, and at the same time, fitting each roller of the at least a roller part between the glass shaft and the drum to stop the glass shaft from being rotated in a reverse direction.
