Abstract

A parking mechanism for a vehicle includes an automatic transmission, a parking gear, a parking pawl, and a parking-pawl turn member. The parking gear is fixed to a part formed by any of an output shaft of the automatic transmission and an intermediate member connected to the output shaft. The parking pawl is turnably attached to a turn shaft that is supported by a plate fastened to a transmission case by a first bolt and a second bolt. The parking-pawl turn member turns the parking pawl into engagement with the parking gear. An extending part formed by extending a support member that turnably supports the part of the automatic transmission is substituted for the plate. The extending part is fastened to the transmission case by the first bolt.

Description

technical field [0001] The invention relates to a parking mechanism of a vehicle. Background technique [0002] As a parking mechanism for a vehicle, the following mechanism is proposed in Patent Document 1, which includes the following parts: a parking gear fixed to an output member of an automatic transmission; a parking lever swingably fixed to a rotary shaft, The rotation shaft is supported by a plate, and the plate is fastened to the transmission case by first and second bolts; and a parking lever swing member swings the parking lever to lock the parking gear freely. [0003] More specifically, the parking lever is fixed to the rotating shaft in a swingable manner, and the rotating shaft is supported by a plate fastened to the transmission case by the first bolt and the second bolt, and the plate is triangular in side view. The lever is configured to engage and lock the parking gear. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2004-44689 [0005] As des...
