PARKING LOCK DEVICE FOR TRANSMISSION

摘要

A parking lock device mounted on a transmission without modifying the constitution of the base transmission as much as possible and is constituted in a compact size. A first coupling member 11 is spline-fitted and fixed to a rear end portion of an output shaft 1 of the transmission by using a fixing nut 5, and a second coupling member 12 is integrally coupled to the' first coupling member 11. A continuously indented portion 11C is formed along the outer circumference of the first coupling member 11. In a park locked state, a pawl portion 31A of a parking pawl 31 arranged on the lower side is brought in mesh with the intended portion 11C. The parking lock device is mounted on the rear end portion of the output shaft 1, and does not require the basic portion of the transmission to be modified. The second coupling member 12. has an extended shaft portion 12C formed in the same shape as the rear end portion of the output shaft 1. Therefore, a coupling 13 connected to the propeller shaft of the vehicle may be a commonly used part irrespective of whether the parking lock device is mounted.
