Narrative:
During IFR tower en route flying south on V-585 (from smf to sck) we were told to contact sck approach control. Smf approach made no mention of any traffic prior to the handoff. While changing frequencys an small aircraft twin appeared at our 12:30 O'clock position closing rapidly. I veered to the left and the small aircraft Y went under us. I have since spoken to the pilot. He mentioned the sun was in his eyes and did not see us till the last second. He mentioned he was not on any type of flight following, but was monitoring approach control. Upon gently querying the sck approach controller about the traffic that had just gone by, controller became noticeably defensive stating that the airplane was not using any radar service. I believe a possible blind spot plus a possible lack of controller responsibility may exist in this general area near and just south of wager intersection.

Title: NMAC BTWN AN SMA SEL ACFT ON AN IFR TRAINING FLT IN VFR CONDITIONS ON AN AIRWAY AND AN SMA TWIN ENG ACFT UNDER NO ATC CTL.
Narrative: DURING IFR TWR ENRTE FLYING S ON V-585 (FROM SMF TO SCK) WE WERE TOLD TO CONTACT SCK APCH CTL. SMF APCH MADE NO MENTION OF ANY TFC PRIOR TO THE HDOF. WHILE CHANGING FREQS AN SMA TWIN APPEARED AT OUR 12:30 O'CLOCK POS CLOSING RAPIDLY. I VEERED TO THE L AND THE SMA Y WENT UNDER US. I HAVE SINCE SPOKEN TO THE PLT. HE MENTIONED THE SUN WAS IN HIS EYES AND DID NOT SEE US TILL THE LAST SECOND. HE MENTIONED HE WAS NOT ON ANY TYPE OF FLT FOLLOWING, BUT WAS MONITORING APCH CTL. UPON GENTLY QUERYING THE SCK APCH CTLR ABOUT THE TFC THAT HAD JUST GONE BY, CTLR BECAME NOTICEABLY DEFENSIVE STATING THAT THE AIRPLANE WAS NOT USING ANY RADAR SVC. I BELIEVE A POSSIBLE BLIND SPOT PLUS A POSSIBLE LACK OF CTLR RESPONSIBILITY MAY EXIST IN THIS GENERAL AREA NEAR AND JUST S OF WAGER INTXN.
