摘要： An irreversible adjustment mechanism comprising a pivoting lever resiliently assisted to a neutral position, an intermediate pivoting part connected to the lever by a driving stage adapted to move the intermediate part only when the lever moves away from its neutral position, a fixed collar, an output part delimiting with the collar wedge-shaped hollow spaces directed in opposite directions, and a locking stage ensuring an irreversible transmission between the intermediate part and the output part with a certain angular play of the intermediate part. The intermediate part is braked with a braking torque sufficient to lock the intermediate part in each return movement of the input part to its neutral position.

摘要： PROBLEM TO BE SOLVED: To provide a rotating direction converting device having a simple rotation transmitting route with the compact design by arranging an input shaft and an output shaft on the same axis.
SOLUTION: The input shaft and the output shaft 1 and 2 are arranged on the same axis, and normal rotation of the input shaft 1 is transmitted as it is to the output shaft 2 by a first one-way clutch 12, and a rotation transmitting means formed of a pair of opposite bevel gears 5 and 6 arranged on the same axis with the input and the output shafts 1 and 2 and an intermediate bevel gear 7 engaged with the opposite bevel gears 5 and 6 at a right angle is provided. Reverse rotation of the input shaft 1 is transmitted to the one opposite bevel gear 5 by a second one-way clutch 13, and normal rotation of the other opposite bevel gear 6 for reversely transmitting the reverse rotation of the opposite bevel gear 5 is transmitted to the output shaft 2 by a third one-way clutch 14. With this compact design formed with a simple rotation transmitting route, rotation of the input shaft 1 in both the normal and the reverse direction is output as one-way rotation to the output shaft 2.

摘要： PROBLEM TO BE SOLVED: To reduce a loud striking sound generated in a belt-type fastening unit utilizing a ratchet mechanism when a taking-up lever is turned to fasten a cargo or the like, or when either a backstop engagement plate or a feeding engagement plate is struck against a valley part of a ratchet. SOLUTION: In order to solve the problems, a plate-like resilient member is arranged near a ratchet and the plate-like resilient member is projected out of teeth segments of the ratchet. Then, just before either the backstop engagement plate or the feeding engagement plate is completely engaged with the ratchet, it is abutted against a striking plate and the striking plate is resiliently deformed, resulting in that a striking energy can be absorbed.

摘要： PROBLEM TO BE SOLVED: To provide a ratchet fitting capable of being fixed at a required opening angle while rotating a rotation fitting to an open direction, and being used as a support mechanism for rocking eaves of a store or a rocking foot rest of a passenger seat in an airplane and the like. SOLUTION: A ratchet 22 of a rotating fitting 20 is pivotally supported by a housing 12 of a fixed fitting 10 so as to freely rotate. By engagement between a claw piece 30 pivotally supported by the housing 12 and a ratchet tooth 23, the rotating fitting 20 is prevented from rotating to a close direction. At a position where a recess portion 31 of a cam plate 30 pivotally supported by the housing 12 corresponds to a claw piece 40, the engagement of the claw piece 40 is accepted, and at a position where a guide portion 32 corresponds to the claw piece 40, the engagement is limited. With the rotation of the rotating fitting 20 to an open direction, the claw piece 30 is successively engaged with the corresponding ratchet tooth 23. When the rotating fitting 20 rotates in the open direction until a predetermined open position, the cam plate 30 is rotated to a position where the guide portion 32 corresponds to the claw piece 40, and the rotation of the rotating fitting 20 to the close direction is accepted.

摘要： PROBLEM TO BE SOLVED: To reduce an invalid movement by braking a support part by a brake torque sufficient for holding an intermediate part in a fixed state at every time when an input part is returned to a neutral position, after the intermediate part locks a fixing stage. SOLUTION: An adjusting mechanism 6 is approximately triangle and has an input means 14, or an annular input cam of three projections 15 with round topmost parts projecting radially outward. The adjusting mechanism is operated by a drive stage 44 connecting the input cam 14 to an intermediate part 20 and a fixing stage 48 connecting the intermediate part 20 to an output cam 35. the drive stage 44 has three pairs of rigid interruption bodies 45, 46 arranged in wedge-shaped regions 22a, 22b on both sides of respective projections 15 of the input cam 14 in an intermediate annular space 22 via a compression spring 47. When an operation lever is moved from a neutral position to the angular direction 8 or direction 10, the input cam 14 firmly fixes the interruption bodies 45, 46 to a support face 21a by the projections 15, a lever is extremely slightly moved by an invalid angle, and the intermediate part 20 is driven.
