Rod assembly and fluid pressure device

A fluid pressure device, comprising:

• a body containing therein a slide hole;
• and
• a rod assembly disposed so as to reciprocate along the slide hole,
• wherein:
• the rod assembly includes a rod member and a packing attached to an outer circumferential part of the rod member and configured to slide along the slide hole;
• the rod member includes, in the outer circumferential part, a stopper receiving groove extending in a circumferential direction;
• a stopper member divided into a plurality of elements in the circumferential direction is installed into the stopper receiving groove,
• wherein the packing includes:
• a packing body portion covering one end in an axial direction of the stopper member and coining into abutment against the outer circumferential part of the rod member,
• a circumference covering portion protruding from the packing body portion in the axial direction to cover an outer circumference of the stopper member, and
• an annular engaging groove formed in an inner circumferential part of the circumference covering portion to elastically engage with the stopper member,
• and wherein
• the packing has an L-shaped cross-section and includes an opening from which an other end in the axial direction of the stopper member is exposed, the packing being integrally formed of an elastic material, and
• the packing covers the stopper member, and thus the stopper member supports the packing and is prevented from coming off the stopper receiving groove.
