Abstract
A transmission mechanism device includes a transmission mechanism including a hollow shaft, and a bearing supporting an outer face of the shaft. A holder holding the bearing is on the inner face of a housing of the transmission mechanism. The holder has a facing face facing an end of the shaft, a tubular portion holding the bearing and protruding in the axial direction radially from the facing face, and a rib inside the tubular portion and protruding in the axial direction from the facing face. The rib extends in a concave shape opening upward. A lower end of an inner face of the rib is below an upper end of an inner face of the shaft when viewed from the axial direction. At least one end of the rib in an extending direction faces an inner face of the tubular portion via a gap when viewed from the axial direction.
