A damper adjusting device is mounted on a base of an exercise apparatus,
including a resistance wheel, a pivoting member, a driving mechanism, and
a biasing member. The resistance wheel is rotatably mounted on the base.
The pivoting member is pivotably mounted on the base, having a driven
portion and a resistance portion. The driving mechanism is mounted on the
base, having a rotatable turntable and a lug formed on the turntable and
spaced from a center of the turntable. The biasing member generates
resilience for keeping the driven portion contacting against the lug.
Accordingly, when the lug is driven to move to further drive the pivoting
member to pivot for an angle, the distance between the resistance portion
and the resistance wheel is also changed to shift the resistance
generated while the resistance wheel turns.
