摘要： An engagement chain has two chain members. Each of the chain members includes link plates, each of which has two pin holes, and coupling pins. The two pin holes are aligned in the advancing/retreating direction and are sized differently from each other. Each of the coupling pins of each chain member is tightly received in the smaller pin hole of the two pin holes of one of any adjacent two of the link plates in the advancing/retreating direction and is loosely received in the larger pin hole of the two pin holes of the other one of the two adjacent link plates. In a state in which the chain members are integrated with each other, any two of the coupling pins that are opposed to each other are in the same received states in the corresponding pin holes.

摘要： A transplanting device separates a seedling bed piece with a seedling from a seedling bed along slits and transplants the separated seedling bed piece to a permanent planting panel. The transplanting device includes a separating mechanism and a transplanting mechanism. The separating mechanism includes a holding member and is capable of separating the seedling bed piece from the seedling bed. The transplanting mechanism is capable of transplanting the separated seedling bed piece to the permanent planting panel. The separating mechanism includes an engagement bar capable of hampering movement of an adjacent seedling bed piece adjacent to a holding-target seedling bed piece held by the holding member by becoming engaged with the adjacent seedling bed piece from a side that is different from a first side, on which the stalk of the seedling grows.

摘要： An object of the present invention is to provide a vehicle parking lock system that realizes a parking lock with a positive user perception, and enables energy and cost reductions without complex control and with a simple configuration. The object is achieved by a selectable clutch configured to be switchable between four operating modes and provided to one of an input shaft, an output shaft, and an intermediate shaft of a transmission. The operating mode of the selectable clutch is controlled based on detection signals of a plurality of sensors to prevent an unintended movement of the vehicle when the vehicle is stationary.

摘要： An object of the present invention is to provide a cam and a one-way cam clutch that realize a reduction in weight and production cost, provide more design freedom in setting the center of gravity of the cam, and achieve high responsiveness. The above object is achieved by a cam configured to make contact with an inner race and an outer race by a rotational moment applied in an engaged direction by an annular spring, in which a plurality of cam plates having an identical outer contour and arranged in parallel along a direction of the pivot axis are coupled together and united by a connecting pin extending in the direction of the pivot axis, and the annular spring is configured to be mountable between adjacent cam plates and/or on an outer side of the plurality of cam plates in the direction of the pivot axis.

摘要： Provided is a tensioner which has a small total number of components and no risk of incorrect assembly, allows easy load change, is easy to assemble, and excellently stabilizes an oil pressure in a pressure oil chamber. The tensioner 100 includes a relief mechanism that relieves oil to the outside of a plunger 110 when the oil pressure in the pressure oil chamber formed between the plunger 110 and a plunger containing hole 121 in a housing 120 increases, relief holes 141 extending through the plunger 120 from the inside of a plunger inner space 111 to an outer circumferential side thereof, and a hole closing member 142 that is pressed into an opening of each of the relief holes 141 on the outer circumferential side.

摘要： An object of the present invention is to provide a chain that is easy to assemble, has a longer life and smaller size, and allows larger tolerance for misalignment. The object is achieved by a chain including a plurality of outer links each having a pair of outer plates and pins, and a plurality of inner links each having a pair of inner plates and bushings, alternately and pivotably coupled together in the longitudinal direction of the chain by the pins rotatably inserted into the bushings, with a position restricting part positioned between each pair of the inner plates to restrict inward movement of each pair of inner plates in the chain width direction. The bushings are rotatably inserted in respective bushing holes of each pair of inner plates.

摘要： An object of the invention is to provide a positive clutch that has a high rigidity and simple structure, and offers potential to allow easy adjustment of torque limit load, suppress friction loss and noise generation, realize a size reduction, and extend the service life. This positive clutch is configured to prohibit relative rotation of an outer and inner races by circumferentially holding each of a plurality of rollers between an outer race slope portion and an inner race slope portion. The clutch includes a torque limiter mechanism, which includes a piston member having a flat portion that forms the outer or inner race slope portion, and a resilient member that applies a constant load on the piston member. The piston member is slidably accommodated in a piston member accommodating hole formed in the outer race or the inner race.
