Abstract

A golf bag includes a base with a U-shaped notch and a wheel set is connected to the base. The wheel set includes a shaft which extends through the notch and two guide members are axially movably connected to two ends of the shaft. Two wheels are connected to two respective outsides of the two guide members. Each guide member has an extension rod which is inserted into the notch and are movably engaged with a V-shaped groove defined in a top surface of a fixed plate in the base. An activation unit has a link and includes a movable member which has a cooperation groove. The two guide extension rods of the guide members are movably engaged with communication portions of the V-shaped groove and the cooperation groove. By pulling the link, the two wheels are pulled toward each other.
