Abstract: Provided is a rotary damper (1) suitable for use as a damper for a brake pedal with a fail-safe feature.
In the rotary damper (1) intended for a brake pedal of an automobile and configured to generate a damping torque by rotation of a casing (11) in a forward direction N relative a rotor (12), the casing (11) is made of thermoplastic resin and is provided with a pair of arms (19a, 19b) projecting radially outward so as to hold a plate (5) therebetween. The plate (5) is configured to rotate about a pedal rotation center in conjunction with the brake pedal (4). Moreover, the arm (19a) out of the arms (19a, 19b), which is located downstream in the forward direction, includes a curved portion (191) with a constant width and a supporting portion (192) located more distal than the curved portion (191) is, and is configured to support the plate (5) with the supporting portion (192).-

Abstract: The present invention enables a simple structure to provide an easy adjustment of damping torque to be caused by applied rotation.
The rotary damper (1) is intend to limit movement of viscous fluid filled in a circular cylindrical chamber (111), thereby generating a damping torque in response to an applied rotational force. The lid (15) is the screw-on type capable of being screwed into the casing (11), and thus adjusting a clearance gap G1 between the lid (15) and each partition (115) by way of changing the screwing amount of the lid (15) into the casing (11) allows amount of viscous fluid moving through the clearance gap G1 to be adjusted, thereby resulting in adjustment of a damping torque to be caused by rotation. In addition, each axial force generation member (17) includes a plastically or elastically deformable element and is located between the lid (15) and the corresponding partition (115) to apply a reaction force to the lid (15). This causes screwing the lid (15) into the casing (11) to generate an axial force, thereby preventing external-leakage of the viscous fluid via a threaded interface between the lid (15) and the casing (11), and allows the leeway for the adjustment of the clearance gap G1 to increase.-

Abstract: To reduce the effect of a steering operation on feeling. A rack bush comprises: a bush body that is accommodated in a cylindrical housing, supports a load exerted on a rack bar while allowing the rack bar to move in the direction of an axial center O, and can be extended and retracted in a radial direction; and an elastic ring mounted on the bush body. The bush body has a mounting groove for mounting the elastic ring, the mounting groove being formed peripherally in an outer peripheral surface, and the mounting groove having a large-diameter part where the circumferential radius of a groove bottom is a first radius r1, and a small-diameter part where said radius is a second radius r2 that is less than the first radius r1. This configuration allows the formation of an elastic ring protruding part, in which the elastic ring protrudes greatly from the outer peripheral surface of the bush body, and an elastic ring embedded part, in which the elastic ring is embedded in the outer peripheral surface of the bush body.

Abstract: Provided is a damper capable of damping a moving member which reciprocates along an axis, using a damping force having a hysteresis property.
A damper includes a cylindrical housing into which a push rod is to be inserted in the direction of an axis thereof, and a damping mechanism placed in the housing and capable of damping the push rod by a damping force having a hysteresis property, wherein the damper is to be attached using a master cylinder mount space of a clutch pedal unit. In the damping mechanism of the damper, engagement between a helical cam groove formed in an inner wall of the housing and a guide protrusion formed on an outer circumference of a rotatable friction disk causes reciprocating linear motion of the push rod to be converted into rotating motion of the rotatable friction disk, and other friction disks, placed on both sides of the rotatable friction disk are pressed against respective sliding surfaces, of the rotating friction disk by an elastic force of a coil spring depending on an amount of displacement of the push rod.-
