Multifunction gauge

A multifunction gauge for checking wear of a sprocket and a roller chain, the sprocket having a plurality of angularly spaced-apart sprocket teeth, and a plurality of sprocket grooves each being defined between a corresponding adjacent pair of the sprocket teeth, the roller chain including a plurality of spaced-apart rollers, and a plurality of chain grooves each being defined between a corresponding adjacent pair of the rollers, said multifunction gauge comprising:

• a checking bar adapted to check wear of the roller chain, and a flexible checking member adapted to check wear of the sprocket and connected pivotally to said checking bar;
• said checking bar having a bar body that has opposite first and second end portions, said first end portion having a first terminating end adapted to engage one of the sprocket grooves when said flexible checking member is used to check wear of the sprocket, said second end portion being formed into a rod-shaped handle adapted for applying force when said flexible checking member is used to check wear of the sprocket, said second end portion having a second terminating end that is opposite to said first terminating end along a longitudinal direction of said bar body;
• said checking bar further having spaced-apart first and second checking projections that project transversely from said bar body between said first and second terminating ends and that are adapted to check wear of the roller chain, said first checking projection being proximal to said first terminating end, said second checking projection being proximal to said second terminating end of said second end portion.
