However, when the load acting on the downward direction of the output shaft is large, the rotation of the output shaft will be faster than the rotation of the input shaft. As a result, the roller may be caught again between the output engaging piece and the outer ring member to become locked. state, so that the output shaft stops
Afterwards, when the input shaft catches up with the stopped output shaft and pushes the roller, the lock is released and the output shaft and the load move, but when this action is repeated to drive the load via the reverse input blocking clutch, the load is not continuously ground drive, the movement of the load in the downward direction is interrupted

Embodiment Construction
[0022] Embodiments of the present invention will be described below. figure 1 It is an explanatory diagram showing an example of a reverse input blocking clutch according to an embodiment of the present invention, figure 1 (a) is the structure diagram, figure 1 (b) is a perspective view of the input member 12A coupled to the input shaft 12, figure 1 (c) is a perspective view of the output shaft 13 . exist figure 1 In (a), the upper half is shown in cross-sectional view.
[0023] Reverse input blocking clutch 11 is used to input to input shaft 12 (in figure 1 In the embodiment, the input shaft 12 is embedded in the central hole of the input member 12A in a non-rotatable manner), and the bidirectional rotational force in the forward rotation direction and the reverse direction is transmitted to the output shaft 13. The bidirectional rotational force of the shaft is transmitted to the output shaft 13, and the rotational force from the output shaft 13 is not transmitted...

An object of the present invention is to suppress vibration caused by frictional sliding between an outer ring member made of a sintered member and a coil spring in a reverse input blocking clutch provided with an outer ring member and a coil spring. The reverse input blocking clutch makes the rolling member (17) stuck on the inner wall of the outer ring member (14) and becomes locked state when the reverse input acts on the output shaft (13), but in the reverse input of the present invention In the blocking clutch, when the output shaft (13) is rotated by the input shaft (12), the output shaft (13) and the outer ring member (14) are rotated integrally by maintaining a locked state to prevent intermittent rotation. At this time, the outer ring member (14) frictionally slides with the coil spring (19), but since the outer surface of the outer ring member (14) of the present invention is processed for reducing surface roughness, the , will not produce vibration, noise.
Description
technical field [0001] The present invention relates to a reverse input blocking clutch for transferring an input from an input shaft to an output shaft without transferring a reverse input from the output shaft to the input shaft. Background technique [0002] The reverse input blocking clutch is a device for transmitting bidirectional driving force from the input shaft to the output shaft and preventing transmission of rotational force from the output shaft to the input shaft. The function of preventing the rotational force from the output shaft (reverse input of the output shaft) is realized by making the roller of the transmission mechanism provided on the reverse input blocking clutch engage the output engagement piece of the output shaft with the Reverse input is blocked between the outer ring members of the clutch to be in a locked state. [0003] In a product equipped with such a reverse input blocking clutch, such as a game machine such as a pachinko machine, there...
