Block-type transformable toy

A block-type transformable toy comprising a plurality of adjacent blocks:

• the adjacent blocks being urged by an elastic cord member in a direction of mutual contact;
• and so that the block-type transformable toy is transformable between a state of being folded and a state of being extended that the extended shape represents an object, by changing the mutual positional relationships between the adjacent blocks:
• at least one pair of the adjacent blocks comprising:
• a first block having a first contact surface and a first inclined surface inclining to the first contact surface, the first contact surface and the first inclined surface being next to each other;
• and
• a second block having a second contact surface and a second inclined surface inclining to the second contact surface, the second contact surface and the second inclined surface being next to each other;
• and able to directly contact with the first contact surface and a first inclined surface of the first block simultaneously;
• wherein the first block and the second block contact each other urged by the elastic cord where the first contact surface and the first inclined surface contact with the second contact surface and the second inclined surface simultaneously, and rotational movement of the first block and the second block around the elastic cord member is restricted.
