When a host 101 is connected to a device 102 via a USB cable 103, the ID terminal on the device 102 is short-circuited to the GND line, hence to reduce the voltage level of the ID terminal. Since power feeding means 109 starts feeding power to the V_BUS terminal when detecting that the voltage level of the ID terminal turns from “H” to “L”, the power is supplied to the host 101 through the V_BUS line of the USB cable 103.

Provided is a hose joint by which an insertion position of a front end of a hose is stabilized to thereby enhance the sealing efficiency and a disconnecting strength between the outer surface of a nipple and the hose. When the hose (H) is inserted, the inner diameter of an inlet portion (3a) of an expandable and contractible sleeve (3) opposed to a decreasing diameter portion (1a2) is set to be larger than the outer diameter of the hose (H) which is inserted along the decreasing diameter portion (1a2) of a bulged portion (1a), whereby the front end of the hose (H) is smoothly introduced between the expandable and contractible sleeve (3) and the decreasing diameter portion (1a2) without causing the front end of the hose to butt against the inlet portion (3a) of the expandable and contractible sleeve (3) and can be inserted to a predetermined position. Thereafter, when pressed by a pressing surface portion (2b) in accordance with the axial movement of a fastening tool (2), the inner diameter of the inlet portion (3a) of the expandable and contractible sleeve (3) is set to be smaller than the outer diameter of the hose (H) inserted along the decreasing diameter portion (1a2) of the bulged portion (1a), whereby the hose (H) is held between the inlet portion (3a) of the expandable and contractible sleeve (3) and the decreasing diameter portion (1a2) of the nipple (1).

A vibration isolator (10) enabling simplification of a passage structure for connecting a negative pressure chamber in which a membrane is used as a partition wall and a valve chamber of a valve mechanism for opening and closing a second restriction passage to an operating pressure supply source, and simplification of connection of the negative pressure chamber and the valve chamber of the valve mechanism to the operating pressure supply source. The inner passage (63) of a communication tube (62) on the inner peripheral side of an outer cylinder member (20) communicates the negative pressure chamber (60) with the valve chamber (102). A pipe connection part (106) and a supply/discharge pipe (110) communicate the valve chamber (102) with the supply/discharge port (114) of a switching valve (112) on the outside of the vibration isolator (10). The switching valve (112) selectively communicates the supply/discharge port (114) to either an intake manifold (130) as the negative pressure supply source, or an atmosphere space. The negative pressure chamber (60) communicates with the valve chamber (102) through the communication tube (62) on the inner peripheral side of the outer cylinder member (20).
