Embodiment Construction

[0034] Next, specific embodiments of the present invention will be described using the drawings.

[0035] [First embodiment of the one-way clutch]

[0036] Figure 1 to Figure 4 The shown one-way clutch 1 is one embodiment of the one-way clutch of the present invention, and includes an outer member 10 , an inner member 20 , a slide member 30 , and a cover member 40 .

[0037] The outer member 10 is provided with: an outer body 11, on the axis P (refer to Figure 4 ) direction has a bottom plate 11a, which is formed into a bottomed cylindrical shape with an opening on the other end side in the direction of the axis P; teeth 12 a ; and a plurality of internal teeth 13 formed on the inner peripheral surface of the main body 11 and protruding radially inward. A circular fitting hole 11b penetrating in the axis P direction is formed in the bottom plate 11a. The hole center of the fitting hole 11b coincides with the axis P. As shown in FIG. The radial direction of the outer bod...

Abstract

The present invention provides a miniaturized one-way clutch and a rotary damper device with the one-way clutch. The claw portion (31) of the sliding member (30) has a retreat surface (31a) that abuts against the inner teeth (13) of the outer member (10) when the outer member (10) rotates to one side relative to the inner member (20). ); and the engagement surface (31b), which is abutted against the internal tooth (13) by the external component (10) rotating to the other side relative to the internal component (20), when the internal tooth (13) and the retreat surface (31a) When abutting, the sliding member (30) slides in the sliding direction and the pawl (31) retreats from the inner teeth (13), and the outer member (10) and inner member (20) rotate independently, when the inner teeth (13) and When the engaging surface (31b) abuts, the inner teeth (13) engage with the engaging surface (31b), and the outer member (10) and the inner member (20) rotate integrally.

Description

technical field [0001] The invention relates to a one-way clutch and a rotary damper device with the one-way clutch. Background technique [0002] Conventionally, there is known a rotary damper provided in an opening and closing portion of a door, for example, and slowing down a door or the like that is biased in one of the opening or closing directions to alleviate the impact. Such a rotary damper may be combined with a one-way clutch to form a rotary damper device with a one-way clutch in order to generate damping force only for rotation in one direction. [0003] For example, in the rotary damper device with a one-way clutch described in Patent Document 1, the one-way clutch is combined with the rotary damper device. The one-way clutch has a rotor shaft coupled to the rotary damper and is connected to the rotor an inner member whose shaft integrally rotates; an outer member that accommodates the inner member so as to be relatively rotatable; and a pair of planetary gears...
