A savings box, comprising:

• a coin-receiving hollow case having a through-hole formed in the top thereof;
• a coin concealment member disposed upright on the top of the coin-receiving hollow case, having an internal space communicating with the through-hole in the coin receiving case via an opening at a lower end of the concealment member, said internal slot being, formed nearly in the middle of two outer flat faces which define a predetermined angle between them;
• two mirrors fixed on the outer flat faces, respectively, of the coin concealment member;
• a camouflaging member attached to the coin concealment member to cover the slot of the coin concealment member as viewed from outside of the savings box;
• a back screen disposed upright on the top of the coin-receiving case and having a camouflaging face exposed to the two mirrors, the camouflaging face being so located that the two mirrors and coin concealment member will not be visible due to reflection of the camouflaging face by the mirrors;
• and
• a coin chute attached to the coin concealment so that the coin chute can be oscillated about a center of oscillation, a first end thereof being exposed out of the slot of the coin concealment member while a second end thereof is disposed in the coin concealment member, a coin passage being formed therein from the first to the second end;
• the coin chute having a center of gravity displaced from the center of oscillation toward the second end thereof so that it oscillates reciprocally when a coin put in rolls on the coin passage.
