The switch actuating piece 13 can be easily removed from the opening 14.

  Therefore, by providing a recess 13b in the contact portion 13b on one surface of the switch operating piece 13, a change is made to the pulling force of the switch operating piece 13, thereby changing the operation of the micro switch 15. .

  For example, the microswitch 15 comes into contact with the recess 13b for a patient who may move to some extent, and the microswitch 15 comes into contact with the smooth surface 13c for a patient whose movement must be strictly controlled. Thus, the switch operating piece 13 may be set in the opening 14.

  In this way, by changing the direction in which the switch operating piece 13 is pulled out from the opening 14, body movement can be detected according to the condition of the inpatient and the burden on the nursing side can be suppressed. .

  In the above embodiment, the example in which the convex portion 18 is formed on the housing 10 side and the concave portion 31 is formed on the hook 30 side as the locking means between the housing 10 and the hook 30 has been described. For example, a concave portion may be formed on the housing 10 side and a convex portion may be formed on the hook 30 side.

  In this case, by forming an inclined surface that inclines along the hook removal direction on each upper surface side of the concave portion of the housing 10 and the convex portion of the hook 30, the male and female combination of the concave portion and the convex portion can be easily released. The housing 10 and the hook 30 can be separated even with a small force.

  In the above-described embodiment, the example of the quadrangular columnar convex portion and the square concave portion has been described as the locking means between the housing 10 and the hook 30. However, the concave portion and the convex portion may have a shape that can be sexed. For example, the convex portion may be a hemispherical protrusion, and the concave portion may be a hemispherical concave portion that matches the convex portion.
