To provide an inexpensive hydraulic power steering controller capable of inhibiting leakage of hydraulic oil.SOLUTION: A hydraulic power steering controller includes a valve body A that controls flow of hydraulic oil which is fed from a pump while being interlocked with a steering wheel turning manipulation, a pump part B that feeds the hydraulic oil, which is controlled by the valve body A, to a steering cylinder according to a steering wheel turning quantity, and a cover part C that covers the end of the pump part B. The valve body A and pump part B have outside surfaces which share an equal outer diameter with a common axis X as a center. The outside surfaces are coupled with each other in a direction along the axis X. The cover part C forms as an integral part a sleeve 20 that is externally engaged with a region ranging from the end position of the pump part B to the valve body A beyond the opposed areas of the pump part B and valve body A respectively.SELECTED DRAWING: Figure 1
【課題】作動油のリークを抑制し得る安価な油圧パワーステアリングコントローラを構成する。【解決手段】ステアリングホイールの回転操作に連動してポンプから供給される作動油の流れを制御するバルブボディAと、バルブボディAで制御された作動油をステアリングホイールの回転量に応じてステアリングシリンダに送り出すポンプ部Bと、ポンプ部Bの端部を覆うカバー部Cとを備え、バルブボディAとポンプ部Bとが共通する軸芯Xを中心に等しい外径となる外面を有し、これらが軸芯Xに沿う方向で連結され、カバー部Cが、ポンプ部Bの端部位置からポンプ部BとバルブボディAとの対向部を超えてバルブボディAに達する領域まで外嵌するスリーブ20を一体的に形成している。【選択図】図1
