<p>PURPOSE: To dispense with adoption of expensive material to a slipper by forming a disc-like slotted on part a lower surface of the slipper pivoted to a base end of a piston, and inserting a disc-like slipper pad in the slotted part, which pad is made of resin and in sliding contact with a thrust plate. CONSTITUTION: A slotted part 81 is formed on a lower surface 83 of a slipper 80 pivoted to a base end of a piston 6, while a groove 87 is formed on its bottom surface 89. The groove 87 is communicated with the outside two communication grooves 88 extended radially. On the other hand, a spherical projection 82 is formed on a head of the slipper 80, and slidably fitted in a spherical recession 62 formed on a base a base end of the piston 6. An oil passage 84 vertically penetrates the slipper 80, and is communicated with an oil passage 61 formed on the base end of the piston 6. Further a resin-made slipper pad 86 in sliding contact with a thrust plate 7 is inserted into the slotted part 81, while a hole 90 communicated with the oil passage 84 is formed on its center.</p> |
