Embodiment Construction

[0043]Hereinafter, embodiments for implementing the present invention will be described with reference to the drawings. In addition, in the following description, the direction in which the rotating shaft 40 of the rotor 30 extends is the axis L direction, and the side of the rotating shaft 40 protruding from the housing 20 in the axis L direction is referred to as the side L1. The side opposite to the side protruding from the housing 20 will be described as the other side L2.

Abstract

The present invention provides a fluid buffer device and buffered equipment capable of properly handling welding raw materials. A fluid damper (10) includes a rotor (30) inserted into a bottomed cylindrical casing (20), and a cover (60) fixed to an opening (29) of the casing (20). A welding protrusion (80) welded to the cover (60) is formed on a part of the inner peripheral surface of the housing (20) in the circumferential direction. On the other side (L2) in the axis (L) direction of the welding range (X) where the welding protrusion (80) is welded to the cover, a position adjacent to the welding protrusion (80) in the circumferential direction is formed. The first outflow preventing parts (91L, 91R) serve as outflow preventing parts (90) for properly handling molten resin exposed from the welding site. In addition, an arc-shaped stepped surface (76) functioning as an outflow restricting portion (95) is provided on the other side (L2) of the axis L direction of the first outflow preventing portion (91L, 91R) to restrict the contact between the exposed resin and O-ring (49) contacts.

Description

Technical field[0001]The present invention relates to a fluid buffer device filled with fluid between a casing and a rotor and a buffered device.Background technique[0002]Patent Document 1 discloses a fluid buffer device in which a fluid such as oil is filled between a bottomed cylindrical case and a rotor. In the fluid shock absorber of Patent Document 1, one end of the rotor (rotating shaft) in the axial direction is arranged inside the housing, a buffer chamber is formed between the rotating shaft and the inner peripheral surface of the housing, and the valve is provided on the side of the rotating shaft The core is arranged in the buffer chamber. When the rotor rotates in the first direction, the radial end of the valve core contacts the inner circumferential surface of the housing. Therefore, the rotation load of the rotor is large. On the other hand, when the rotor rotates in a direction opposite to the first direction, a gap is generated between the valve element and the inne...
