置。 A press-fitting device for press-fitting the valve stem oil seal, whose inner part is made of an elastic material such as rubber, into the valve guide of the cylinder head is arranged above the valve guide so as to be able to move up and down. A press-fitting ram has a ring-shaped pressing surface for pressing the shoulder of the oil seal, and the valve stem oil seal is supported by the tip of a rod that is slidably housed in the press-fitting ram. When holding, the pilot pin protrudes outward from the center of the tip surface of the press-fit ram and penetrates into the valve stem oil seal, and when the valve stem oil seal is press-fitted into the valve guide, the position of the press-fit ram tip surface is detected, After the valve stem oil seal is press-fitted into the valve guide, the pilot pin is removed from the valve stem oil seal. , a press-fitting device characterized by raising a press-fitting ram.
