Abstract
The masking jig includes a contact member and a support unit. The contact member includes a through-hole allowing for insertion of a rod-like piston rod, and a deformation part around the through-hole configured to get elastically deformed by insertion of a male thread of the piston rod into the through-hole and contact the outer peripheral end face of the piston rod. The support unit supports the contact member such that the contact member moves in a direction intersecting an axial direction of the piston rod.
