摘要:
A fastening part tightening management system (1) that manages a tightening state of a fastening part such as a screw to fix a constituent part of an aircraft in an aircraft assembling process includes a manual torque wrench (2) that tightens a fastening part up to a set torque while activating a tightening torque and detects and transmits tightening torque information acting on the fastening part, a marking pen (3) that performs marking to the fastening part, the tightening operation of which is ended by the manual torque wrench (2), detects a writing pressure in the marking, and transmits marking completion information; an information processing device (5) that determines a tightening state of the fastening part based on the tightening torque information and the marking completion information, and a mobile information terminal (4) that notifies an operator of a determination result obtained by the information processing device (5).

Using a device to assemble a swash plate-type fluid machine for incorporating a shaft assembly, which has a plurality of pistons each installed on a swash plate via a pair of shoes matching with both end surfaces of the swash plate, respectively, into a cylinder block. The device includes an assembly support portion and a cylinder block support portion. The assembly support portion is for supporting the shaft assembly in a vertical axis posture with the respective pistons suspended by the swash plate. The cylinder block support portion for supporting the cylinder block. The assembly support portion and the cylinder block support portion approach each other to insert the pistons of the shaft assembly into a corresponding one of cylinder bores of the cylinder block.

Disclosed is a self-illuminating measurable-point member comprising; a light source, a fine through-hole which permits light from the light source to permeate there-through, and a diffusible member which diffuses light permeating the fine through-hole. Light from the light source is condensed via the fine through-hole and diffused via the diffusible member.

A large-diameter-side end surface (104a) of a cotter (104) can be supported by a cotter holder (32) from below through inserting a shaft member (102) along an inner periphery of the cotter (104) from above the cotter (104). In this state, a protrusion (104b) of the cotter (104) and an annular groove (102a) of the shaft member (102) are fitted to each other, and the cotter (104) and a retainer (103) are taper-fitted to each other. Consequently, the cotter is prevented from being unstable, and hence it is possible to assemble the retainer (103) and the cotter (104) to the shaft member (102) with good accuracy.

To provide a joining and uniting means which does not cause two metal plate materials, which are to be joined into a unitary structure by curling, to become out of alignment when they are put together, and which does not, moreover, require an operation for aligning a projection or a cut and raised portion and a hole with each other, a projection (11) is formed on an end portion (21) of one metal plate material (5), and this projection (11) is pushed forcibly into an end portion (22) of the other metal plate material (9, 10), whereby two metal plate materials are joined into a unitary structure.
