摘要： A driving force transmission apparatus includes: a motion power transmission part for transmitting a motion power via a driving medium formed by a belt or a chain; and a tensioner for applying a tension to the driving medium. The tensioner includes: a compression spring for biasing the driving medium; a stopper for preventing the compression spring from being compressed to a length less than a predetermined length; and an adjustment part for pushing the compression spring to be the predetermined length in a direction toward the driving medium. According to this configuration, the tension of the driving medium is dominant at installation. When the driving medium becomes fatigue to some extent, the stopper of the tensioner becomes off and the compression spring absorbs the vibration of the driving medium. As a result, the exchange timing of the tensioner can be extended by a simple configuration.

摘要： A flange joint for structural members is provided, wherein by avoiding stress concentration at a welded portion, the cross-sectional size can be determined based on the base material strength, and a structure can be reduced in weight and size. In a flange joint for structural members, structural members are connected to each other in a state where an end face, for example, of an H-shaped steel beam is connected to a structural-member-connecting face of an end plate by welding and a non-connection face of the end plate is coupled to another structural member. The structural-member-connecting face of the end plate, to which the end face of the H-shaped steel beam is connected, is provided with recessed grooves along the shape of the welded portion of the end face.
