PROBLEM TO BE SOLVED: To provide a single arm type current collection device capable of reducing aerodynamic sound generated from the surrounding of a connection part of an arm and a collector head.SOLUTION: There is provided a single arm type current collection device (1) comprising a collector head (2) containing a slider contacting a contact wiring, and an arm (4) for lifting up and down the collector head. On an end part of the arm, a connection member (45) which is connected to the collector head in rigid connection, at least two rotation shafts (C1, C2) which form a part of a link mechanism (44) which moves the collector head so as to maintain a horizontal state when an inclination angle of the arm is changed, and are connected to the connection member, and a cover (5) for covering the connection member including the two rotation shafts, are provided. The collector head (2) is provided on a rear part of at least one of the two rotation shafts (C1, C2), and when the collector head (2) is viewed from a front side, a height of a part which is exposed to an upper part of the cover on the collector head (2) is higher than a height of a part hidden by the cover.SELECTED DRAWING: Figure 2

    【課題】アームと舟体との連結部分の周辺から生じる空力音を低減することのできるシングルアーム型集電装置を提供する。【解決手段】接触架線に接触する摺り板を含んだ舟体(2)と、舟体を昇降するアーム(4)とを備えたシングルアーム型集電装置(1)である。アームの端部には、舟体に剛接続される接続部材(45)と、アームの傾斜角度が変化したときに舟体を水平を保つように移動させるリンク機構(44)の一部を構成し、接続部材と連結される少なくとも2つの回動軸(C1、C2)と、2つの回動軸を含めて接続部材を覆うカバー(5)とが設けられ、舟体(2)は2つの回動軸(C1、C2)の少なくとも一方の後方に配置され、且つ、舟体(2)を前方から見たときに、舟体(2)におけるカバーの上方に露出する部分の高さよりも、カバーにより隠される部分の高さの方が長くなるように構成される。【選択図】図2
