LID-BODY OPENING/CLOSING APPARATUS FOR USE IN VEHICLES

A lid-body opening/closing apparatus for use in vehicle is provided that can avoid a decrease in the closure-tightness capability, which holds a lid body in a closed position and can reduce the occurrence of abnormal noise. A lid-body opening/closing apparatus (1) comprises a housing (90), a linearly-movable shaft (10), a rotary shaft (30) that is mounted around the linearly-movable shaft (10), and a stopper mechanism (50, 60) that switches between a blocking state and a nonblocking state. The linearly-movable shaft (10) comprises: a linearly-movable-shaft main body (11), which is inserted through the interior of the rotary shaft (30); and an elastic body (80), which is provided on the terminal end portion of the linearly-movable-shaft main body (11) and is composed of a material that is softer than the material constituting the linearly-movable-shaft main body (11). The elastic body (80) comprises: a cushioning part (81), which protrudes from the linearly-movable-shaft main body (11) toward a lid body (5); a sealing part (83), which makes ring-shaped contact within the rotary shaft (30); and a connecting part (85), which connects the cushioning part (81) to the sealing part (83) within the linearly-movable-shaft main body (11).
