Abstract
A first body is bonded with a second body to accommodate a sensor element therein. An annular convexity is formed at either the first body or the second body along with its peripheral end border. On the other of the first body and the second body, an annular concavity is formed to engage with the convexity. The convexity engages with the concavity to form an inner gap and an outer gap. Glue is filled in the inner gap and the outer gap. The peripheral surface of the convexity and the peripheral surface of the concavity, where the glue is bonded, have plural protrusions.
Claims9
A bonding structure to bond a first body and a second body air-tightly, comprising:
- a convexity which is formed circumferentially in one of the first body and the second body;
- a concavity which is formed in another of the first body and the second body to engage with the convexity, wherein the convexity and the concavity form a gap between a peripheral surface of the convexity and a peripheral surface of the concavity;
- and
- adhesive material filled in the gap to bond the convexity and the concavity, wherein
- a peripheral surface of the gap has a protrusion protruding in a radial direction, and
- the first body has a pressure sensor element, and the second body has a pressure inlet that leads pressure to the sensor element.
