LUBRICATION STRUCTURE OF GEAR CHANGE MECHANISM

摘要

A lubrication structure of a gear change mechanism includes an actuation valve, a valve body, a detent member, and an elastic contact member. The actuation valve is to set the gear change mechanism to a selected shift position status. The valve body is to house the actuation valve. The detent member is disposed in a vicinity of the valve body and is movable by an operation of the actuation valve. The valve body includes a supply port to supply a hydraulic oil to the detent member. The actuation valve is to communicate the supply port and a drain oil passage in the valve body with each other in a case where a predetermined shift position is selected. The elastic contact member is engaged to one of a plurality of groove portions provided in the detent member.

1. A lubrication structure of a gear change mechanism, comprising:
an actuation valve that displaces, in accordance with a shift position selected by a driver of a vehicle, the gear change mechanism to the shift position that has been selected; a valve body that houses the actuation valve; a detent member that is disposed in a vicinity of the valve body and that is interlocked with an operation of the actuation valve; and an elastic contact member that is elastically engaged in a selective manner to a plurality of groove portions formed in the detent member, wherein the valve body includes a supply port that supplies a hydraulic oil to the detent member, and the actuation valve communicates the supply port and a drain oil passage in the valve body with each other when the driver selects a predetermined shift position.
