PURPOSE:To reduce the number of parts by extending the arm section from the end section of gear along the outercircumference of shaft while integrally forming a fixed projection on the pressure contacting face at the underside of arm section then fitting said projection into a hole made in the outercircumference of shaft. CONSTITUTION:The speed meter drive gear 5 has an arm section 6 extending continuously from the gear body 16 while having an arched arm 10 separated by the cuttings 7, 8 and a fixed projection 12 is formed integrally at the inside of the tip of arm 10. Said projection 12 is fitted in a hole 20 made in the outercircumference of main shaft 3. Consequently, the fixing structure can be formed only with the fitting hole at the shaft side and a gear without requiring special parts such as a stopper ring, steel ball, etc. |
