Abstract
A hydraulic tappet comprises a body which comprises an outer tube, an inner tube and an upper portion which connects the two tubes at the upper end. Within the inner tube, there are provided inner and outer plungers. The outer plunger abuts a valve stem of an engine valve in a DOHC-type engine. The outer plunger is supported by a reinforcement member directly or via the inner plunger to provide high rigidity.
