PROBLEM TO BE SOLVED: To provide a high-pressure fuel supply pump that can inhibit inclination of a valve body and constrain the valve body so as to be slidable in an axial direction, whereby a seat surface of the valve body can come into contact with a seat part further strongly.SOLUTION: The high-pressure fuel supply pump includes: a compression chamber for compressing fluid; and a discharge valve disposed between the compression chamber and a discharge passage. The discharge valve includes: a part to be guided that is formed on a side opposite to the compression chamber: and a guiding part disposed on a side opposite to the compression chamber relative to the discharge valve to guide a sliding part of the part to be guided.SELECTED DRAWING: Figure 4 【課題】弁体の傾きを抑制することができ、弁体を軸方向に摺動可能に拘束できるため、弁体のシート面をより強固にシート部に当接させることが可能となる高圧燃料供給ポンプを供給する。【解決手段】流体を圧縮するための加圧室と、前記加圧室と吐出通路との間に配置される吐出弁と、を備えた高圧燃料供給ポンプにおいて、前記吐出弁は前記加圧室と反対側に形成される被案内部を備え、前記吐出弁に対して前記加圧室と反対側に配置され、前記被案内部の摺動部をガイドする案内部を備えた。【選択図】 図４
