DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a rubber base 30 for vibration isolation is formed in a substantially rectangular disk shape. This rubber stand 30
Is formed in a shape for supporting the pump block 6 placed thereon, and a support piece 35 for preventing the displacement of the pump block 6 is provided on the upper surface of the rubber base 30 so as to protrude upward. In the vicinity of the four corners of the rubber base 30, insertion holes 36 penetrating vertically are formed. The pump block 6 is placed on the upper surface of the rubber base 30, and is inserted from the lower surface of the rubber base 30 into the insertion hole 36. The rubber base 30 is attached to the lower surface of the pump block 6 by inserting the screw 40 and screwing the screw 40 to the pump block 6. Fixing portions 31 are provided near the four corners of the rubber stand 30, and each fixing portion 31 has a mounting hole 3.
4 are perforated. In the case of the present embodiment, the fixing portions 31 at the two corners on one end side of the rubber base 30 hang down from the rubber base 30 downwardly with thin, leg-shaped legs 32 having a U-shaped cross section. Are provided integrally, and a fixed portion 31 is provided in a three-dimensional structure. The leg 32 may be in the shape of a rectangular tube as shown in FIG. Further, since the fixing portion 31 at the two corners at the other end of the rubber stand 30 cannot be formed into a three-dimensional structure due to space, a thin portion 37 is provided on the periphery of the fixing portion 31 so as to be L-shaped when viewed from a plane. is there. A fitting recess 34a is provided below the mounting hole 34 provided in the fixing portion 31. A mounting boss 26 is attached to the mounting base, which is the bottom plate of
Is protruding.

In mounting the rubber base 30, the fixing portions 31 are arranged on the mounting bosses 26, the fitting recesses 34a of the mounting holes 34 are fitted on the upper ends of the mounting bosses 26, A screw 33 such as a tapping screw is inserted into the mounting hole 34, the screw 33 is screwed into the mounting boss 26, and the rubber base 30 is mounted. At this time, the rubber stand 30 can be attached simply by screwing a screw 33 such as a tapping screw, so that the workability of the assembly is improved as compared with the conventional method of bonding the vibration-proof rubber feet and tightening the hexagon nut. Good. Also, by attaching the pump block 6 via the rubber stand 30, the cost of parts can be reduced as compared with the conventional case where four anti-vibration rubber feet using insert molding of a male thread bar are used. Furthermore, the fixing part 31
Is provided through the thin legs 32 and the thin portions 37, so that sufficient vibration isolation can be ensured. At this time, since the leg portion 32 has a U-shaped cross section or a rectangular cylindrical shape, the strength can be ensured even if it is thin. When the fixing portion 31 is provided with the thin leg portion 32 or the thin portion 37 interposed therebetween, sufficient vibration isolation can be secured, but without the leg portion 32 or the thin portion 37, the vibration isolation can be obtained. Absent. That is, when the rubber base 30 has a uniform thickness as shown in FIG. 5, the thickness is increased to some extent in order to support the weight of the pump block 6. There is only it, it cannot absorb vibration and does not have a vibration proof structure.

In the case of this embodiment, the four fixing portions 31
Of the two, the two fixing portions 31 are provided via the leg portions 32 and the two fixing portions 31 are provided via the thin portion 37.
The individual fixing portions 31 may be provided via the leg portions 37.

[0011]

[Effects of the Invention] As described above, the present invention provides a fixing portion at the lower end of a thin-walled leg that hangs down from a rubber base, and screws a screw into a mounting base through a mounting hole provided in the fixing portion to fix the leg. As a result, it can be attached to the mounting base simply by screwing in screws, as well as being able to be attached to the mounting base via thin legs, and the assemblability can be improved compared to the conventional , Moreover, since the attached at only one rubber stand state, and are not able to achieve part to cost reduction as compared with the conventional male screw rod using four vibration proof rubber legs insert molding, also fixed
A fitting recess is provided on the lower surface side of the mounting hole of the
