摘要： A rotation transmission device includes coaxial input and output shafts (1 and 2), a pair of opposed bevel gears (3 and 4) rotatably mounted around the input shaft (1), and an intermediate bevel gear (5) meshing with the opposed bevel gears (3 and 4). The output shaft (2) and one of the opposed bevel gears (3) are rotationally fixed to each other. A first one-way clutch (6) is provided through which the rotation of the input shaft (1) is transmitted to the one of the opposed bevel gears (3). A second one-way clutch (7) is provided through which the rotation of the input shaft (1) in the reverse direction is transmitted to the other of the opposed bevel gears (4). Thus, the output shaft (2) can be rotated in the normal direction irrespective of whether the input shaft (1) is rotated in the normal direction or in the reverse direction.

摘要： A rotation transmission device is provided which is simple in structure and which can stably transmit rotation. It includes input and output shafts (1 and 2) which are coaxial with each other, a pair of opposed bevel gears (3 and 4) rotatably mounted around the input shaft (1), and an intermediate bevel gear (5) meshing with the opposed bevel gears (3 and 4). The output shaft (2) and one of the opposed bevel gears (3) are rotationally fixed to each other. A first one-way clutch (6) is provided through which the rotation of the input shaft (1) is transmitted to the one of the opposed bevel gears (3). A second one-way clutch (7) is provided through which the rotation of the input shaft (1) in the reverse direction is transmitted to the other of the opposed bevel gears (4). Thus, the output shaft (2) can be rotated in the normal direction irrespective of whether the input shaft (1) is rotated in the normal direction or in the reverse direction. This device is made up of a smaller number of parts than conventional devices including three one-way clutches and is less likely to suffer from problems resulting from misalignment of the clutches during rotation.

摘要： A clutch unit includes axially arranged input, output and reverse input gears, and a spring clutch. The input and output gears respectively include radially opposed input and output clutch portions. The spring clutch is tightly bound to the input clutch portion and includes coil springs each having transmission and release hooks. With the transmission hooks in engagement with the output clutch portion, the release hooks are spaced forward from the transmission hooks. From an unlocking state, when the release portion is reverse rotated by distance c while pushing the release portions, the spring clutch is unlocked, and when a reverse rotational portion is reverse rotated by distance b, it engages a reverse rotation engaging portion. When the release portion is further reverse rotated after the spring clutch has been unlocked by distance a, the release portion engages the hook engaging portion and stops. a>b>c.

摘要： The object is to improve the control of a spring clutch, thereby simplifying the structure of a rotational direction switching clutch unit and thus reducing its cost.The clutch unit includes an input gear 12, an output gear 13 and a reverse input gear 14 which are axially arranged, and a spring clutch 26. The input gear 12 includes an input clutch portion 15, and the output gear 13 includes an output clutch portion 16 that is radially opposed to the input clutch portion 15. The spring clutch 26 is tightly bound to the input clutch portion 15. The spring clutch includes coil springs 27 each having a transmission hook 28 at one end and a release hook 29 at the other end. With the transmission hooks 28 in engagement with a hook engaging portion 21 of the output clutch portion 16, the release hooks 29 are spaced in a forward rotational direction from the transmission hooks 28 by a predetermined distance. From an unlocking starting state in which the release portion is in contact with the release hooks, when the release portion is moved in the reverse rotational direction B by a distance c while pushing the release portions, the spring clutch is unlocked, and when the reverse rotational portion is moved in this direction by a distance b, it engages a reverse rotation engaging portion 22. Further, when the release portion further moves in the reverse rotational direction after the spring clutch has been unlocked by a distance a, the release portion engages the hook engaging portion 21 and stops. The distances a, b and c are determined to satisfy the relation a>b>c.
