Abstract
A sprinkler head has a shock absorber. The shock absorber may be a heat collection plate disposed below a thermosensitive part of the sprinkler. The heat collection plate may be formed with a recess or at least one notch around an attachment portion to which it may be attached to the sprinkler head. The recess or notch serves to reduce strength of the heat collection plate, whereby the heat collection plate may be easily deformed upon application of a shock or external force thereto. Thus, any external force or shock is prevented from being transmitted to the thermosensitive part. Deformation of the heat collection plate also facilitates visual recognition of a sprinkler head to which external force has been given.
