To provide a noncontact-type pantograph contact force measuring apparatus capable of measuring contact force between an overhead wire and a pantograph, even when having two rows of shoe bodies and further even when the pantograph for power collection is an object.SOLUTION: The noncontact-type pantograph contact force measuring apparatus for measuring contact force between a pantograph 2 including shoe bodies 5 and 6 coming into contact with an overhead wire 1, and support parts 7-10 for supporting the shoe bodies 5 and 6 by springs 7a-10a, and the overhead wire 1, comprises: pairs of markers 11A-14A and 11B-14B to be disposed on a vertically upper location B of lateral faces A out of the lateral faces A of the support parts 7-10 and lateral faces of the shoe bodies 5 and 6; line sensor cameras 15-18 collectively capturing an image of a pair of upper/lower markers (11A, 11B, etc.); and a contact force calculation section 23 that detects respective positions of the markers 11A-14A and 11B-14B on the basis of the image captured by the line sensor cameras 15-18 and calculates the contact force on the basis of the respective detected positions and velocity of a vehicle 3.SELECTED DRAWING: Figure 1 【課題】舟体が２列であっても、さらに集電を行うパンタグラフが対象であっても、架線とパンタグラフとの接触力の測定を可能とする非接触式パンタグラフ接触力測定装置を提供する。【解決手段】架線１と接触する舟体５，６、及び、バネ７ａ〜１０ａにより舟体５，６を支持する支持部７〜１０を備えるパンタグラフ２と、架線１との接触力を測定する非接触式パンタグラフ接触力測定装置であって、支持部７〜１０の側面Ａ、及び、舟体５，６の側面のうち前記側面Ａの鉛直方向上方位置Ｂに配される、一対のマーカー１１Ａ〜１４Ａ，１１Ｂ〜１４Ｂと、上下一対のマーカー（１１Ａ，１１Ｂ等）を一括して撮影するラインセンサカメラ１５〜１８と、ラインセンサカメラ１５〜１８によって撮影された映像に基づき、マーカー１１Ａ〜１４Ａ，１１Ｂ〜１４Ｂの各位置を検出し、検出した各位置、及び、車両３の速度に基づき、接触力を求める接触力算出部２３とを備える。【選択図】図１
