<p><P>PROBLEM TO BE SOLVED: To provide a solenoid that achieves both suppression of contamination effect and improvement of operation response characteristics. <P>SOLUTION: The solenoid 1 that drives a master device by moving a shaft 5 coupled to a plunger 4 in a shaft direction includes: first and second bearings 7 and 8 that slidably hold the shaft 5 by sandwiching the plunger 4; a second bearing through passage 64 that penetrates the second bearing 8 so as to connect a plunger rear chamber 75 and second bearing rear chamber 76; and a shaft through passage 65 that penetrates the shaft 5 in the shaft direction so as to connect the master device and second bearing rear chamber 76. This configuration allows a hydraulic fluid of the master device to be passed in the through passage 65, second bearing rear chamber 76 and second shaft through passage 64 so as to be introduced into the plunger rear chamber 75. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
