Provided is a support and guide device capable of smoothly shifting a moving block (2) configured to move along a guide track (1) from one of a plurality of track rails (4) forming the guide track (1) to another of the plurality of track rails (4) even when clearances are secured at joints between the plurality of track rails (4). The plurality of track rails (4) are arranged in series, and the moving block (2) is movable along the guide track (1) while being sequentially shifted between the plurality of track rails (4). Each of the track rails (4) has a guide surface (41) formed along a longitudinal direction of each of track rails (4). The moving block (2) includes contact elements (3) configured to travel on the guide surface (41) of the track rail (4). Each of the track rails (4) has auxiliary sliding surfaces (5) formed on both end portions of the each of the plurality of track rails (4) in the longitudinal direction, the auxiliary sliding surfaces (5) being formed side by side with the guide surface (41) and being inclined with respect to the guide surface (41). The moving block (2) includes leading sliding portions (9) each being configured to face one of the auxiliary sliding surfaces (5) of the track rail (4) when the moving block (2) reaches one of both end portions of the track rail (4) in the longitudinal direction.

A seat moving/securing device 10 includes a long reference member 11 extending in a longitudinal direction of a seat installation surface and securely installed, a leg part attachment member 50a having securely installed therein a leg part of a seat, a linear guide 20 attached between the long reference member 11 and the leg part attachment member 50a and enabling the leg part attachment member 50a to move horizontally along a longitudinal direction of the long reference member 11, and a locking mechanism 60 securely installed on the leg part attachment member 50a. A coil spring 68 serving as an elastic body exhibiting a pressing force is installed between the leg part attachment member 50a and the linear guide 20. Due to having this type of configuration, the seat moving/securing device 10 can move and secure a seat 200 easily and quickly.

Provided is a ball joint that is less affected by fluctuations in environmental temperature, and is capable of stabilizing a torque value required to rock a ball stud in a holder. The ball joint includes: a ball stud (1) including: a shaft member (11); and a ball portion (10) formed at one end of the shaft member (11); and a holder (2) made of a synthetic resin and configured to accommodate the ball portion in a pivotable manner. The holder (2) includes: an opening portion (30) from which the shaft member protrudes; a first member (20) including a first ball sliding contact surface (24) having a concave spherical shape approximate to a spherical surface of the ball portion; and a second member (3) including: a second ball sliding contact surface (31) having a concave spherical shape approximate to the spherical surface of the ball portion; and the opening portion (30) formed in a center of the second ball sliding contact surface. Further, the first member (20) and the second member (3) respectively include joining surfaces (25, 32) fixed to each other by welding, and respectively include fixation reference surfaces (28, 34) that are brought into abutment against each other.
摘要:
A heat-treatment device 10 includes a table 11 on which a ring-shaped workpiece W can be placed, and a pair of heat processing units 20 for heat-processing the peripheral surface of the workpiece W. The heat-treatment device 10 is used for obtaining the workpiece W having desired properties by the heat-processing the workpiece W while the pair of heat processing units 20 move in opposite directions along the peripheral surface of the workpiece W. The heat-treatment device 10 is configured in such a way that a pair of revolving arms 30 movable relative to the table 11 oscillate the pair of heat processing units 20 relative to the workpiece W, thereby heat-processing the peripheral surface of the workpiece W. By adopting such a configuration, it is possible to obtain a heat-treatment device heat-processing the entire circumference of a ring-shaped workpiece.
