PROBLEM TO BE SOLVED: To maintain an adequate position of a damper spacer for a long time. SOLUTION: A protect spacer 3 is interposed at a lower section of a damper rubber 4 for absorbing an impact generated when a print lever is restored. A positioning projection 11 at an inner face of a lever holder 10 is allowed to be not directly contacted with the damper space 6 by a protection piece 3c which is integrally formed on the protect spacer 3. As a result, in the case where the print lever is abutted thereto, even when a component force in the face direction of the damper space 6 is generated, the component force is suppressed by the protection piece 3c, thereby preventing a shift of the damper space 6 in the face direction.
