Title: Parking lock device
Inventor: OKAMURA MINORU
IPC: F16H63/34
Filed: 1982-07-30
Abstract: PURPOSE:To dispense with a surplus space by attaching a parking cam to a shifter rail through an interlock to move said cam together with the shifter rail only in shifting to parking for parking locking. CONSTITUTION:When a change lever is set to the parking position, a shifter rail 44 is moved to the right side through a selection lever 52 of a selection device 41 and a shift arm 50, so that a cam body 62 is movably urged to the right side by a spring 68 and a ball locks a parking gear 37. When the cam body 62 is shifted to the retreat stage, the shfiter rail 44 is moved to the left side. Thus, an interlock pin 63 is pulled out of a groove 65 in the rail 44 and put into a groove 64 in a shifter rail 43 to fix the cam body 62 to the rail 43. Thus, only the rail 44 is moved singly. When the cam body is shifted to third or fourth speed, the shifter rail 43 is moved. Since the pin 63 engages said groove 65, only shifter rail 43 is moved singly.
