According to locksmith book written by Bill Phillips, which is a helpful book for home and car locksmiths, there are holes inside the cylinder case that match in size and position, called upper pin chambers.

Tumbler Locks Operation – Mobile Locksmith
The important thing about these locks is that the position of each pin determines whether the cylinder can rotate. Pressure from the springs and key determine Pin positions.
When you don’t use a key, gravity and the downward pressure drive the top pins into the plug until they get on their identical bottom pins.
When a pin is in its upper pin and in a lower pin chamber simultaneously, it obstructs the plug from turning. If you want to rotate it with force, you would probably bend the pin.
When you insert a proper key into the keyway, it slides under all the pins and lifts them to the shear line. The precise key will suit the keyway and have fitly spaced cuts of the depths to match each bottom pin length.
When all the top and bottom pins meet at the line, they allow the plug to rotate freely. When the plug is rotated, the top pins separate from the bottom pins.
