Claims

[Claims for utility model registration] First operating position, second operating position, third operating position,
a shift lever that is sequentially operated to a parking operation position; a parking lock arm that is rotated to lock the output shaft of the transmission; a first shift rod located at each of the four operating positions; a second shift rod parallel to the first shift rod and fixed to the housing; and a second shift rod slidable on the first shift rod and the second shift rod, respectively. The first one is fitted and equipped with a shift fork for changing gears.
a shift head; a second shift head slidably fitted to the first shift rod and the second shift rod, respectively, and operatively connected to the lock arm; and a first shift rod and a second shift rod within the first shift head; The shift lever is selectively engageable and is always engaged with the first shift rod to move the first shift head together with the first shift rod, but when the shift lever is between the third operating position and the parking operating position. a first engagement pin that engages with the second shift rod to prevent movement of the first shift head when the first shift rod is in the second shift head; and a first engagement pin that is selectively engageable with the first shift rod and the second shift rod within the second shift head. provided and constantly engaged with the second shift rod to prevent movement of the second shift head;
a second engagement pin that engages with the first shift rod to move the second shift head together with the first shift rod when the shift lever is between a third operating position and a parking operating position; a first detection switch that is activated when the first shift rod moves from the second operating position to the first operating position or from the third operating position to the parking operating position; 1. A shift device for a vehicle transmission, comprising: a second detection switch that is activated when the switch is moved to a certain position.
