Pressure sensor
First Claim
1. A pressure sensor, comprising:
- a housing;
a pressure receiver sealing an opening of the housing and including a flexible portion of which one main surface is a pressure receiving surface and a marginal region positioned outside the flexible portion; and
a pressure sensing element including a pressure sensing portion, a first base portion, and a second base portion, the first base portion and the second base portion being respectively connected to both ends of the pressure sensing portion and arranged in a direction parallel to a displacement direction of the pressure receiver, whereinthe first base portion is coupled to a central region of the pressure receiver, the central region being a reverse side of the pressure receiving surface, and the second base portion is coupled to one of the marginal region of the reverse side and an inner wall of the housing, the inner wall being opposed to the first base portion, through a connector.

Abstract
A pressure sensor includes: a housing; a pressure receiver which seals an opening of the housing and transmits pressure from outside the housing to the inside of the housing; and a pressure sensing element having a pressure sensing portion and a pair of base portions which are respectively coupled to both ends of the pressure sensing portion. In the pressure sensor, a force detecting direction is set to be a detection axis, a line connecting the pair of base portions and a displacement direction of the pressure receiver are arranged in parallel, one of the base portions is coupled to a central region, which is displaced by the pressure, of the pressure receiver, and the other of the base portions is coupled to a marginal region, which is at a fixing side, of the pressure receiver through a connecting member.
