<P>PROBLEM TO BE SOLVED: To provide a gear mounting structure using a snap fit for allowing easy mounting of a gear without lowering the strength of a sap fit portion. <P>SOLUTION: A gear shaft 2 protruded on a body frame 1 in the lateral direction has the snap fit portion 23 cylindrically formed with slits 22a, 22b formed ranging from the front end to the axial direction. A gear member 3 is mounted with a mounting hole portion 31 at the center inserted through the front end of the gear shaft 2. A cylindrical reinforcing member 4 is inserted into the gear shaft 2 to support the snap fit portion 23 at its lower face, thus preventing the flexion of the snap fit portion 23. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
