An improved drive mechanism for a conveyor. An endless belt is mounted for travel on the frame of the conveyor and is driven by a drive unit (9). The drive unit (9) includes a supporting structure or housing (10) that carries a power source, such as a motor (22). The output shaft (24) of the motor is connected by a flexible drive member (26) to a pair of drive spindles (19, 20) that support the conveyor belt (3). The spindles which are journaled for rotation on slides (41, 43) that are mounted far movement on the supporting structure of the drive unit. A drive mechanism, such as a fluid cylinder (47), is operably connected to the slides (41, 43) to move the slides in unison to tension the belt (3).
