To provide a valve device which throttles a flow rate at one flow-out port without changing a flow rate at the other flow-out port.SOLUTION: A valve device includes: a housing H defining a flow-in port 11d, a first flow-out port 11b which is open in an internal peripheral surface 11a centered at an axial line S while being separated in a circumferential direction Cd and forms a first opening width in the circumferential direction, a second flow-out port 11c forming a second opening width, and an accommodation chamber C; and a cylindrical valve body 30 which is arranged in the accommodation chamber and can open and close the first flow-out port and the second flow-out port by turning around the axial line. The valve body 30 includes: an internal passage Ip in communication with the flow-in port; a first flow-out communication port 31a expanding into one direction in the circumferential direction while being continuous to a region facing the first flow-out port in order to provide communication between the internal passage and the first flow-out port, and forming an opening width which is greater than the first opening width; and a second flow-out communication port 31b expanding into the other direction in the circumferential direction while being continuous to a region facing the second flow-out port in order to provide communication between the internal passage and the second flow-out port, and forming an opening width which is greater than the second opening width.SELECTED DRAWING: Figure 6 【課題】一方の流出口の流量を変えずに他方の流出口の流量を絞る弁装置を提供する。【解決手段】流入口１１ｄ，軸線Ｓを中心とする内周面１１ａにおいて周方向Ｃｄに離れて開口しかつ周方向において第１開口幅をなす第１流出口１１ｂ及び第２開口幅をなす第２流出口１１ｃ，収容室Ｃを画定するハウジングＨと、収容室に配置され軸線回りに回動して第１流出口及び第２流出口を開閉し得る筒状の弁体３０を備えた弁装置において、弁体３０は、流入口に連通する内部通路Ｉｐと、内部通路と第１流出口とを連通させるべく第１流出口に臨む領域に連続して周方向の一方向に向けて拡開し第１開口幅よりも大きい開口幅をなす第１流出連通口３１ａと、内部通路と第２流出口とを連通させるべく第２流出口に臨む領域に連続して周方向の他方向に向けて拡開し第２開口幅よりも大きい開口幅をなす第２流出連通口３１ｂを含む。【選択図】図６
