A motor attaching structure and a motor attaching method capable of preventing vibration from occurring are provided. A shaft holding a rotor of a motor rotatable thereon is fixed to a first holder. An annular second holder holds a core serving as a stator of the motor with a peripheral portion thereof being arranged between a case and the first holder. Screws to be used as fixing members fix the case, the first holder, and the second holder integrally to each other. The second holder further includes a holding portion which holds the stator and an absorbing portion located between the peripheral portion and the holding portion and possessing a thickness less than the peripheral portion.

Motor attaching structure and motor attaching method

A fixing member includes a first side, second side parallel to the first side, and face provided between the first side and second side and including an opening. The face is provided at a position separate from a line connecting between the first side and second side, first side is brought into line contact or point contact with the first structure, and second side is brought into line contact with an end part of a strain body constituting a strain sensor, the end part being provided on the first structure. A screw is inserted into the opening and is screwed into the first structure.

Strain sensor fixing device and torque sensor using the same

A torque sensor includes a first structure, a second structure, a third structure provided between the first structure and the second structure, and at least two sensor units provided between the first structure and the second structure. A plurality of first contact portions having a structure integrated with the first structure is provided inside an outer peripheral portion of the first structure, first distal ends are arranged near the outer peripheral portion, and the first distal ends are in contact with a first attachment portion. A plurality of second contact portions having a structure integrated with the second structure is provided at a part of an inner peripheral portion of the second structure, second distal ends are arranged near the inner peripheral portion, and the second distal ends are in contact with a second attachment portion.

Torque sensor attachment structure

According to one embodiment, a CPAP device includes a housing, a fan, and a sound absorbing material. The housing has a first air inlet and a first air outlet, and a flow channel guiding air sucked through the first air inlet to the first air outlet. The fan has a second air inlet and a second air outlet, the second air inlet is disposed in the direction intersecting the flow channel, and the second air outlet is disposed in the direction along the flow channel. The sound absorbing material is provided with a recess constituting a part of the flow channel and facing the second air inlet of the fan, the recess having a diameter which is greater than a diameter of the second air inlet of the fan and which is equal to or smaller than the width of the flow channel.

CPAP device

A fan unit produces an airflow. A pressure difference generating member causes a pressure difference in the airflow. A sensor detects a pressure difference between the air pressure on the upstream side of the pressure difference generating member and the air pressure on the downstream side thereof. A straightening plate is provided between the fan unit and the pressure difference generating member, and straightens the airflow produced by the fan unit. A straightening plate comprises a first fin and a second fin which are arranged along the airflow, and a lattice-like third fin which is arranged on the downstream side of the first fin and the second fin, and through which the airflow through the first fin and the second fin passes.
