Between a bottom wall 18 of the plunger 12 and a body 11, a high pressure chamber 22 is sectioned. Inside the partition member 13 within the plunger 12, a low pressure chamber 23 is sectioned. Outside the partition member 13 within the plunger 12, an oil passage 40 is sectioned. Between the peripheral wall 19 of the plunger 12 and the partition member 13, a spacer 100 is interposed. Thank to the spacer 100, the partition member 13 is held in the plunger 12 and the oil passage 40 is defined. |
