In this embodiment, a portion in which the delay valve 46 and the proportional pressure reducing valve 47 are disposed is formed integrally with the body 75B. That is, the delay valve 46 and the proportional pressure reducing valve 47 are arranged in the body 75B together with the first to third normally open solenoid valves 59, 63, 66 and the first to third normally closed solenoid valves 62, 65, 69. Will be established.

  By the way, the first to third normally open solenoid valves 59, 63, 66 and the first to third normally closed solenoid valves 62, 65, 69 are disposed on the body 75B with their operating directions parallel to each other. Center axes C1, C2 of the delay valve 46 and the proportional pressure reducing valve 47 are parallel to the first to third normally open solenoid valves 59, 63, 66 and the first to third normally closed solenoid valves 62, 65, 69. Set to

  Further, the first to third normally open solenoid valves 59, 63, 66, the first to third normally closed solenoid valves 62, 65, 69, the delay valve 46, and the proportional pressure reducing valve 47 protrude from the body 75B. The portion is covered with a synthetic resin cover 78B fastened to the body 75B, and a control unit (not shown) is accommodated in the cover 78B so as to be supported by the cover 78B.

  According to the third embodiment, the part in which the delay valve 46 and the proportional pressure reducing valve 47 are disposed is formed integrally with the body 75B, so that the hydraulic pressure control device 77B, the delay valve 46, and the proportional pressure reducing valve 47 are integrated. Can be summarized more compactly.

  Further, the operating directions of the first to third normally open solenoid valves 59, 63, 66 and the first to third normally closed solenoid valves 62, 65, 69, the delay valve 46 disposed in the body 75B, and the proportional pressure reduction. Since the central axes C1 and C2 of the valve 47 are parallel, the hydraulic pressure control device 77B, the delay valve 46 and the proportional pressure reducing valve 47 can be further compacted, and the first to third normally open solenoid valves 59 can be used. 63, 66 and the first to third normally closed solenoid valves 62, 65, 69, the delay valve 46 and the proportional pressure reducing valve 47 can be easily assembled to the body 75B.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the present invention described in the claims. Is possible.
