Embodiment Construction

[0036] Hereinafter, embodiments of the present invention will be described based on the drawings. Figure 1 to Figure 7 shows the first embodiment. Such as figure 1 as well as figure 2As shown, the reverse input blocking clutch is composed of a reverse input blocking mechanism 1 and an action control mechanism 2 that controls the action of the reverse input blocking mechanism 1, and the input side part of the reverse input blocking mechanism 1 is connected with A motor (not shown) is connected to an output side member, and a driven member (not shown) operated by driving the motor is connected.

[0037] Such as figure 1 as well as image 3 As shown, the above-mentioned reverse input blocking mechanism 1 is composed of an input shaft (input side member) 3, an output shaft (output side member) 4, a two-stage cylindrical outer ring 5 disposed radially outside of the output shaft 4, The lock release piece 6 having a plurality of pillars 6a inserted into the radial gap between...

Abstract

The invention provides a reverse-input cutoff clutch. This reverse-input cutoff clutch is configured by combining: a reverse-input cutoff mechanism (1) for, in a state where an outer ring (5) disposedradially outward of an output shaft (output side member) (4) arrested so as to be unrotatable, transmitting rotation of an input shaft (input side member) (3) to the output shaft (4) and blocking rotation of the output shaft (4) in response to reverse-input torque applied to the output shaft (4) by locking the output shaft (4) with the outer ring (5); and an operation control mechanism (2) for, when not being operated, arresting the outer ring (5) of the reverse-input cutoff mechanism (1) so as to be unrotatable, and releasing the outer ring (5) so as to be rotatable by means of a manual operation. Thus, if the operation control mechanism (2) is not operated, it is possible to obtain a state where the rotation of the output shaft (4) in response to reverse-input torque is blocked, and theoperation control mechanism (2) can be easily switched, simply by a manual operation thereof, to a state where the rotation of the output shaft (4) in response to reverse-input torque is permitted.

Description

technical field [0001] The present invention relates to a reverse input blocking clutch which transmits rotation of an input side member to an output side member when an input torque is applied, and which does not rotate for a reverse input torque. Background technique [0002] The reverse input blocking clutch transmits the rotation to the output member when input torque is applied to the input member, and does not rotate when the reverse input torque is applied to the output member. In this reverse input blocking clutch, there is a system for locking the output-side member against reverse input torque (hereinafter, this system is referred to as a "lock-up type"). [0003] For the above-mentioned lock-up type reverse input blocking clutch, there are many structures, that is, the input side member and the output side member that rotate around the same axis are provided between the input side member and the output side member to transmit the rotation of the input side member ...
