<p>PURPOSE:To improve productivity and operability. CONSTITUTION:The device is provided with a 1st flange 49 and a 2nd flange 38 abutting respectively on a connection gear 48 and a 2nd gear 37 in the gear engaging state with each other. The outside diameters of these 1st flange 49 and 2nd flange 38 are set respectively in the same dimensions as pitch circular diameters of the connection gear 48 and the 2nd gear 37. So, the connection gear 48 and the 2nd gear 37 can be engaged by making the 1st flange 49 and the 2nd flange 38 abut each other at the assembling time, therefore, the generation of fault in the gear engagement due to the variance of adjustment is prevented. By preventing the generation of the gear engagement fault, the generation of cogging in a rotary dial 25 at the time of shuttle mode is prevented.</p> |
