ベアのベルト取付装置。1. A pair of pulleys rotatably attached to both ends of a frame, a pair of fixed side bearings attached to one end of the frame and supporting a shaft of one of the pulleys, and the other end of the frame. A pair of movable side bearings that are inserted into an elongated hole formed in the longitudinal direction of the frame and movably attached to the frame to support the other pulley, and a belt stretched between the pulleys. A belt mounting device for a belt conveyor, comprising: an adjusting unit that adjusts the positions of the movable bearings in the elongated holes so that the tension of the belt increases. A bearing body that is removably inserted so that the end portion of the shaft is detachably inserted, and the bearing body that is formed on the outer periphery of the shaft side end portion of the bearing body. Depending on the rotation angle, there are two states: a state in which the bearing body is engaged with a peripheral portion of the elongated hole to prevent the bearing body from coming off the elongated hole, and a state in which the bearing body is inserted into and removed from the elongated hole. One of two states is selected, an adjusting body formed at the end of the bearing body opposite to the shaft side end and having a dimension larger than the width of the elongated hole, and prevention of slipping out of the retainer. A groove formed in a direction parallel to the longitudinal direction on an end surface of the adjusting body opposite to the bearing main body at a time, one end of each of the adjusting means being rotatably attached to the frame. The adjustment is performed between a bolt that is arranged to be able to move in and out of the groove of the adjustment body, a press nut that is screwed into the bolt, and the press nut that is screwed into the bolt arranged in the groove. Hold the body and A belt mounting device for a belt conveyor, comprising a tightening nut for fixing a position.
