Power transmission device

A power transmission device comprising:

• a drive plate;
• a torque fluctuation inhibiting device configured to inhibit fluctuations in torque;
• a first inertia block including a first threaded hole and a second threaded hole, the first inertia block disposed between the drive plate and the torque fluctuation inhibiting device in an axial direction;
• a second inertia block including a third threaded hole, the second inertia block disposed between the drive plate and the torque fluctuation inhibiting device in the axial direction, the second inertia block disposed away from the first inertia block at an interval in a circumferential direction;
• a first bolt screwed into the first threaded hole of the first inertia block, the first bolt fastening the drive plate and the inertia block therethrough to each other;
• a second bolt screwed into the second threaded hole of the first inertia block, the second bolt fastening the torque fluctuation inhibiting device and the first inertia block therethrough to each other;
• and
• a third bolt screwed into the third threaded hole of the second inertia block, the third bolt fastening the drive plate and the second inertia block therethrough to each other.
