Description

The present invention relates to a locking device, particularly an automobile shift lever locking device that locks a shift lever provided in an automobile.

In an automatic transmission, a shift lever that swings around a horizontal axis that intersects the traveling direction of an automobile is used. The shift lever is positioned at a plurality of shifting positions by being connected to the transmission by a shifting cable. Therefore, when attaching the shift cable to the shift lever, it is necessary to lock the shift lever at a specific shift position such as a neutral position where the transmission is not locked. Therefore, conventionally, by attaching a positioning pin to the shift lever, the shift lever is locked so as not to move from a specific shift position. Further, the positioning pin is removed and discarded after the transmission cable is attached.

Patent Document 1 discloses a control lever locking device that locks a control lever provided in a transmission at a connection position where a transmission cable is connected by a positioning member. The control lever swings around the vertical axis. When the worker inserts the positioning member (lock member) into the opening formed in the case of the transmission, the positioning member is mounted at the locked position. The upper end of the positioning member engages with the control lever at the locked position. When the control lever moves in the disengagement direction by operating the shift lever, the positioning member is lowered to the unlocked position by its own weight, and the lock of the control lever is released. However, in Patent Document 1, since the control lever rotates around the vertical axis and the positioning member is lowered by its own weight, the structure of Patent Document 1 cannot be applied to the shift lever that rotates around the horizontal axis.
