Claims

[Scope of utility model registration request]

A gas introduction chamber is formed at one end of the through hole provided in the valve housing, and the valve head at the tip of the valve stem inserted into the through hole projects into the gas introduction chamber, and the valve stem is pulled and biased by a spring to open the valve head. In the valve for a shiatsu instrument, which is closed by bringing the valve into close contact with the valve seat, a first cylinder is formed in the middle part of the valve housing, and the valve stem is rotatably inserted and attached to a piston that is slidably fitted into the first cylinder. , a valve opening operation mechanism for introducing an external working fluid into the first cylinder and pushing the piston against a spring is provided, and a second cylinder is formed in the upper part of the valve housing perpendicularly to the valve rod, and A piston biased by a spring is slid into a piston with a rack connected to the second cylinder, the rack of the piston is meshed with a pinion attached to a valve stem, and external working fluid is introduced into the second cylinder to resist the spring. 1. A valve for an acupressure instrument, characterized in that it is provided with a valve stem rotation operation mechanism that rotates a valve stem by pushing a piston.
