Abstract: <P>PROBLEM TO BE SOLVED: To provide a shock absorber, thoroughly absorbing a shock applied to an engine hood, and sufficiently relaxing a shock applied to an object to be protected colliding with the engine hood due to the reaction of the shock.  <P>SOLUTION: When the object 36 to be protected collides with the engine hood 30 of the vehicle and the engine hood 30 cannot completely absorb a shock due to the collision, the tip part 20 of a piston 16 is pressed by the engine hood 30. Therefore, a fluid 14 in a cylinder 12 receives the load from the piston 16 so that the internal pressure of the cylinder 12 is increased. Further, when the internal pressure of the cylinder 12 reaches a preset pressure of a chuck valve 22, the fluid 14 in the cylinder is discharged. With such discharge, the piston 16 is reduced in length so that the shock received by the engine hood 30 is relaxed. Thus, the shock applied to the object 36 to be protected can be also relaxed.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
