Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a high-pressure fuel pump that minimizes wear of a piston.SOLUTION: The invention relates to a high-pressure fuel pump (10) having a pump piston (22) and having a piston rotation inducing device (38). In the high-pressure fuel pump (10), the piston rotation inducing device (38) induces a rotation of the pump piston (22) about a movement axis (26), along which the pump piston (22) moves in translational fashion, during the operation of the pump piston (22).SELECTED DRAWING: Figure 1 【課題】ピストンの摩耗を最小にした燃料高圧ポンプを提供する。【解決手段】ポンプピストン（２２）とピストン回転誘導装置（３８）とを備えた燃料高圧ポンプ（１０）であって、ピストン回転誘導装置（３８）が、ポンプピストン（２２）の作動時に、それに沿ってポンプピストン（２２）が並進運動する運動軸線（２６）を中心にしたポンプピストン（２２）の回転を誘導する、燃料高圧ポンプ（１０）る。【選択図】図１
