To provide a car washing machine in which an advancing/retracting drive device for side nozzles is arranged inside side parts of a portal frame, which can ensure a sufficiently long advancing/retracting stroke for the side nozzles and enables the side nozzles to advance/retract with a sufficient operational stroke without specially widening left and right side part widths of the portal frame even when the frontage of a portal frame is expanded or the diameter of side brushes is increased.SOLUTION: An advancing/retracting drive device Dns includes a double speed mechanism L that has: a first mechanism L1 which has a first output part 73 capable of displacing in a substantially-advancing/retracting direction of side nozzles Ns and is installed in a portal frame 1 so as to be entirely contained in a side part 1s of the portal frame; a second mechanism L2 which has a second output part 75 capable of displacing in the substantially-advancing/retracting direction, and in which a side nozzle base part 22 is held by the second output part; and an interlocking mechanism I which connects the first and second mechanisms in an interlocking manner so as to increase a displacement stroke of the second output part 75 relative to the side part 1s than a displacement stroke of the first output part.SELECTED DRAWING: Figure 12

    【課題】サイドノズル用の進退駆動装置を門型フレームの側部内に配置した洗車機において、サイドノズルの進退ストロークを十分長く確保可能として、門型フレームの間口を拡げたり或いはサイドブラシを大径化したりした場合でも、門型フレームの左右の側部幅を特別に拡幅することなくサイドノズルを十分な稼動ストロークを以て進退駆動可能とし、洗車機の小型化を図る。【解決手段】進退駆動装置Dnsは、サイドノズルNsの略進退方向に変位可能な第1出力部73を有して門型フレーム側部1s内に全体が収まるよう門型フレーム1に設置される第1機構L1と、略進退方向に変位可能な第2出力部75を有し且つ第2出力部にサイドノズル基部22が保持された第2機構L2と、第2出力部75の側部1sに対する変位ストロークを第1出力部の変位ストロークよりも増加させるように第1,第2機構相互を連動連結する連動機構Iとを含む倍速機構Lを備える。【選択図】 図12
