<p><P>PROBLEM TO BE SOLVED: To provide a brake device capable of controlling the caulking load. <P>SOLUTION: The brake device includes: a housing 31 in which an oil path (oil path 10a etc.) is formed internally; a valve body (ball member 72) disposed on the oil path (oil path that connects an oil path 10a and a reservoir 15); and a sheet member 71 that has a seat part 71a to which the valve body abuts. The sheet member 71 is fixed by caulking to a bottomed hole (pressure regulating valve storing hole 31c) formed in a housing 31, and communicate to the oil path 10a. The sheet member 71 includes: a groove (fitting groove 71f) formed to the circumference of the sheet member 71, and in which the meat of the housing 31 flows, when the sheet member 71 is fixed by caulking; amd an exhaust passage (communicating part 71j, communication hole 71c or a through-hole 71b) which is formed on the sheet member 71 and makes the groove communicate with the external of the groove of sheet member 71. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
