A wire harness includes at least one conductive path, and an exterior member having a tubular shape and made of resin, the exterior member covering the conductive path. The exterior member includes a flexible tube portion with flexibility and a non-flexible tube portion with low flexibility lower than the flexibility of the flexible tube portion. At least one of the flexible tube portion and the non-flexible tube portion includes a thick portion and a thin portion which are arranged in a tube axis direction, the thick portion and the thin portion being different in thickness.

A conduit made of a synthetic resin, having an inner surface and an outer surface, having concave portions and convex portions alternately and continuously provided in the length direction. The conduit is bendable. The conduit includes outer wall parts extending with a first width in the length direction; inner wall parts positioned radially inside relative to the outer wall parts and extending with a second width in the length direction; and side wall parts joining the outer wall parts and the inner wall parts so that the outer wall parts and the inner wall parts are alternately and continuously provided in the length direction. The outer surfaces of the outer wall parts each have, at both ends in the length direction, protruding parts, which protrude in the radial direction.

The invention includes a tubular main body that protects an electric wire accommodated in an internal space, and a tubular or annular outer layer body stacked concentrically with the main body on an outer peripheral surface of the main body. The outer layer body is either a molded body formed into a shape having a hardness lower than that of the main body, and capable of absorbing sound when the outer layer body comes into contact with an external contacting object, or a molded body including a material having a hardness lower than that of the main body, and capable of absorbing sound when the outer layer body comes into contact with an external contacting object.

A four-layer-structured water passing device is provided, in which a first sleeve and a second sleeve are disposed between an elastic inner tube and an outer cloth sheath. When the water passing device is connected with a pressurized water source, the first sleeve can quickly eliminate or reduce the impact wave strength when receiving a strong expansion impact from the elastic inner tube, such that the first sleeve can gently transmit the fluctuation to the second sleeve, and the second sleeve extends the outer cloth sheath to the limit length, so as to avoid damage caused by frequent direct contact friction between the elastic inner tube and the outer cloth sheath. The water passing device is also configured to avoid permanent deformation and abrasion at the joint position between the elastic inner tube and the outer cloth sheath, and thus prolong the service life of the water passing device.

A hose arrangement includes an outer tube of flexible material and an inner tube of an elastic material for carrying fluid. Due to an action of the elastic inner tube, the hose has a shorter length in a contracted state in the absence of fluid pressure in the interior of the inner elastic tube and a longer length in an expanded state when the fluid pressure is applied to the interior of the elastic inner tube. The tube has an undulating state in the contracted state and controls and contains expansion of the inner tube when the hose is in the expanded state. At least one sleeve portion is provided between the elastic inner tube and the outer tube along a part of the elastic inner tube where undulation of the outer tube occurs in the contracted state for protecting the elastic inner tube from abrasion undulations of the outer tube.

A conduit for routing connectivity cables. The conduit including a bottom including consecutively connected bottom members extending a longitudinal length of the conduit. A first side and a second side are connected to the bottom. The first side including consecutively connected first side members extending the longitudinal length and the second side including consecutively connected second side members extending the longitudinal length. The bottom, the first side, and the second side extend along a center axis of the conduit, the center axis extending the longitudinal length of the conduit.

The present invention relates to a telescopic drainpipe assembly, which includes a spiral telescopic pipe body and a first adapter connected to one end of the spiral telescopic pipe body. The first adapter includes a hollow first adapter seat and a first pipe connector connected to the first adapter seat, the first pipe connector is spirally provided, and the first pipe connector is in threaded connection to the spiral telescopic pipe body. The telescopic drainpipe assembly is capable of increasing the drainage length as required, or shortening the length as required for storage. Moreover, the first adapter is capable of being installed to the spiral telescopic pipe body through threaded connection. The structure is reasonable, easy to disassemble and assemble, convenient for replacing the spiral telescopic pipe body as needed, and the first adapter can be reused, thereby effectively saving usage, costs.
