The utility model discloses a tensile rod and a bracket. The tensile rod includes a first pulling rod, a second pulling rod, and an extruding assembly. The first pulling rod has a pulling end and an inserting end that are opposite to each other. An inserting end of the second pulling rod is removably interposed in the first pulling rod. The extruding assembly is mounted at the inserting end of the second pulling rod and abuts against an inner wall of the first pulling rod to provide a uniform extruding friction force from the inserting end of the second pulling rod to the inner wall of the first pulling rod. The utility model improves the structure of the tensile rod, improves the support stability of the tensile rod, and extends the service life of the tensile rod.

A compression lock assembly for an adjustable length rod assembly with inner and outer tubes is provided. The compression lock assembly has an adapter adapted to be connected to rotate with the inner tube. An elastomeric ring with an inner opening and outer diameter is concentric and disposed coaxially with the adapter. A threaded fastener extends through the elastomeric ring and is fixed to the adapter. A lock nut is disposed about the threaded fastener and fixed to rotate with the elastomeric ring. The locking nut moves along the threaded fastener to compress the elastomeric ring and expand the outer diameter from a first diameter to a second diameter greater than the first diameter as the elastomeric ring is rotated relative to the adapter.

In an electrically adjustable steering of the present embodiment, a first telescopic actuator is disposed between a top bracket or a mount bracket on a vehicle body side and a steering jacket. The steering jacket includes a plurality of jacket members that overlap each other so as to be able to expand and contract in an axial direction. A motor of the first telescopic actuator is fixed to the top bracket or the mount bracket on the vehicle body side.

Rod fixing device with the same force irrespective of whether movement of a rod is up or down. A locking mechanism moves with a first rod inside a second rod and a stopper having a contacting surface portion contacting an inner circumferential surface of the second rod. A holder which rotatably holds the stopper so that the contacting surface portion contacts the inner circumferential surface of the second rod, and a spring imparts the stopper with a forces generating a fixing frictional force between the first rod and the second rod by causing the contacting surface portion to come into contact with the inner circumferential surface of the second rod. Movement of the first rod toward one side causes the contacting surface portion to rotate toward a side separating from the inner circumferential surface of the second rod, and movement of the first rod toward the other side is a movement against the fixing frictional force.

[Problem] To provide a rod fixing device capable of operating with substantially the same magnitude of force irrespective of whether the direction of movement of a rod is up or down, and a telescopic rod unit employing the same. [Solution] A locking mechanism 13 which moves integrally with a first rod 11 inside a second rod 12 comprises a stopper 15 having a contacting surface portion 15c capable of coming into contact with an inner circumferential surface 12a of the second rod 12, a holder 14 which rotatably holds the stopper 15 in such a way that the contacting surface portion 15c is capable of coming into contact with the inner circumferential surface 12a of the second rod 12, and a coil spring 16 which normally imparts to the stopper 15 an elastic force for generating a fixing frictional force between the first rod 11 and the second rod 12 by causing the contacting surface portion 15c of the stopper 15 to come into contact with the inner circumferential surface 12a of the second rod 12, wherein the configuration is such that movement of the first rod 11 toward one side causes the contacting surface portion 15c to rotate toward a side separating from the inner circumferential surface 12a of the second rod 12, and movement of the first rod 11 toward the other side is a movement against the fixing frictional force.

A guide rail assembly for a submersible machine as well as a guide rail holder for such a guide rail assembly is described herein. The guide rail holder includes a radially extending support body and an axially extending post, which is rigidly connected to the support body and which is adapted to be inserted into an end of the guide rail. An engagement head is connected to the post at a distance from the support body and has a greater radial extension than the post. The engagement head includes a radially expandable member that is adapted to be reversibly manipulated between an active state, in which the expandable member is in engagement with the guide rail, and an inactive state, in which the expandable member is disengaged from the guide rail.
