摘要： A belt conveyor in which a housing is provided at each longitudinal end of the main frame for accommodating a pulley therein. An endless belt is passed around the pulleys and extend along the upper and lower surfaces of the main frame. Each of the housings consists of a pair of housing blocks attached to either side surface of each end portion of the main frame to rotatably received the pulley therebetween. Each of the housing blocks is provided with a pair of L-shaped pawls which are slidably received by slots provided in the upper and lower surfaces of the main frame, and guide projections slidably received by slots provided in lateral surfaces of the main frame. The slots in the lateral surfaces may have a T-shaped cross section so that the housing block may be secured to the side surface of the main frame by passing a threaded bolt through the housing block and threading it with a nut longitudinally slidably but otherwise unremovable received by the slots in the side wall surfaces of the main frame.
