To clearly switch between a DA section and a first-speed section.SOLUTION: A control mechanism unit of a floor hinge 10 is provided with: a first-speed flow path 42 and a DA flow path 43 that connect a second oil chamber 12b to a first oil chamber 12a to distribute hydraulic oil; a hold open start valve 41 that is provided so as to be contacted with/separated from a piston member 19 and that controls the distribution of the hydraulic oil from the second oil chamber 12b to the first-speed flow path 42 and the DA flow path 43; a hold open release valve 44 that is provided between the second oil chamber 12b and the first-speed flow path 42 so as to permit or stop the distribution of the hydraulic oil from the second oil chamber 12b to the first-speed flow path 42; and a DA oil leakage prevention valve 46 that is provided in a connection flow path 45 for connecting the DA flow path 43 and the first-speed flow path 42 so as to normally stop the distribution of the hydraulic oil through the connection flow path 45 and to permit the distribution of the hydraulic oil from the DA flow path 43 through the connection flow path 45 to the first-speed flow path 42 when inner pressure of the hydraulic oil becomes equal to or higher than a prescribed level in the DA flow path 43.SELECTED DRAWING: Figure 1
【課題】ＤＡ区間と１速区間とを明確に切り替える。【解決手段】フロアヒンジ１０の制御機構部は、第２の油室１２ｂと第１の油室１２ａをつないで作動油の流通を行う１速流路４２およびＤＡ流路４３と、ピストン部材１９と接離可能に設けるとともに、第２の油室１２ｂから１速流路４２とＤＡ流路４３への作動油の流通を制御するホールドオープン開始弁４１と、第２の油室１２ｂと１速流路４２との間に設けることで第２の油室１２ｂから１速流路４２に対する作動油の流通の許可又は停止を行うホールドオープン解除弁４４と、ＤＡ流路４３と１速流路４２とを接続する接続流路４５中に設けられ、常には接続流路４５における作動油の流通を停止し、ＤＡ流路４３内の作動油の内圧が所定以上に高くなったときにはＤＡ流路４３から接続流路４５を介して１速流路４２に対する作動油の流通を許可するＤＡ油漏れ防止弁４６を備える。【選択図】図１
