PURPOSE: A detect assembly of operating power of the latter gear shift section is provided to enable two curved lines having different curvature radiuses to maintain their curved shapes, thereby keeping regular operating power even in the latter gear shift unit. CONSTITUTION: A control finger(4) is combined with a control shaft which receives operating power of a gear shift lever. The control finger accomplishes a gear shift operating tool of a manual transmission. A shift rail(2) changes each shift gear end through a shift of the control shaft during transmission. The control finger operates a lug combined with the shift rail. To keep gear shift operating power during transmission, a poppet ball is contacted with the control finger through elastic power of a spring.
Abstract:
A device for preventing the vibration of a gear for a manual transmission is provided to stop a rotational input shaft with small power by using a five-stage driving gear. A control shaft(21) performs a linear movement or rotates by a manual transmission to perform a selective operation and a gear shifting operation. A control finger(22) is installed on the control shaft. The control fingers have a protruded portion so that they are located on grooves of a forward shift lug(24) and a backward shift lug(25). A backward plate(30) is rotatably installed on the control shaft. The backward plate has a protruded portion so that it is located on the groove of the backward shift lug when the control finger is located on a groove of the forward shift lug. A spring(32) provides elastic force to rotate the backward plate to opposite a direction to the rotation of the control finger. A protrusion(22a) is protruded on the control finger so that the rotational position of the backward plate is limited.

PURPOSE: A shift guide mechanism of a manual transmission is provided to reduce the number of parts due to a simple guide structure by operating a guide wire to a removing unit and a hanging groove of a control shaft and to decide accurately a shift level by preventing clearance in the selecting direction. CONSTITUTION: A shift guide mechanism of a manual transmission is composed of a control shaft(50) moved axially in a selecting motion and rotated in a shifting motion according to operations of a shift lever and a guide unit(60) positioned across the control shaft in the transmission. The control shaft comprises a removing unit(51) and a hanging groove(53) circumferentially formed around the removing unit. The control shaft is moved axially for the selection motion without hanging to the guide unit by the removing unit and hung to the guide unit for the shifting motion by the hanging groove.

PURPOSE: A snap ring is provided to improve the assembling work of the snap ring by simply assembling the snap ring through manually pushing the snap ring. CONSTITUTION: A snap ring includes a stopper section(10), which are inserted into a slot(2) formed at an outer peripheral portion of a shaft(1) so as to prevent the shaft from being axially moved. An insertion part(20) is integrally formed with the stopper(10). The insertion part(20) is bent in such a manner that a gap is formed between the slot(2) of the shaft(1) and an end portion(4) of the shaft. The stopper section(10) has an opening(12), which is engaged with the slot(2) of the shaft(1). A protrusion(6) is formed at the end portion(4) of the shaft(1) so that the insertion part(20) is easily coupled with the shaft(1). An insertion hole(22) is formed in opposition to the end portion of the shaft(1) so as to receive the protrusion(6).

CONSTITUTION: A reverse speed change operation apparatus comprises a 5-R range shift lug(2) connected with a gear shifting lever side, a reverse shift lever(4), an idler gear(6) moved straight according to the operation of the reverse shift lever and geared with, and a positioning device installed to a side of the reverse shift lever. The 5-R range shift lug performs rectilinear reciprocation. The 5-R range shift lug is inserted in the reverse shift lever and the reverse shift lever is rotated in shifting into R-range. The positioning device decides the speed change position of the N-range and R-range. The positioning device is connected to a protrusion(22) protruded to a side of the reverse shift lever and supported to a transmission housing(20). The positioning device includes a coil spring(24) to produce buckling between the protrusion and transmission housing. Therefore, the exact speed change position is decided.
