A shift lever assembly for a vehicle includes a housing having an inner space and an open part. The open part is provided at a lower part of the housing and is open in upward and downward directions. A shift lever is rotatably mounted in the inner space by being inserted into the inner space from a lower side to an upper side of the inner space through the open part. A bracket is assembled with the lower part of the housing to close the open part and allowing the housing to be fixed to a vehicle body.
