An angle formed on a side of a bucket by a first line segment that connects a first pivot region of a bell crank relative to a boom and a second pivot region of the bell crank relative of a connecting link and a second line segment that connects the first pivot region and third a pivot region of the bell crank relative to a tilt cylinder is no more than 206.5&#xb0;. An angle formed by the second line segment and a line segment that connects the third pivot region and fourth a pivot region of the tilt cylinder relative to a structural body is, in a fork-attached state, no more than 72.3&#xb0;. When a pivot region of the fork relative to the boom is substantially 1.5 m from the ground, a lower end of the bell crank is located higher than a lower end of the fork.

In a wheel loader, an angle formed by a first line segment Lconnecting a pivot position Y on a boomof a bell crankand a pivot position X on a connecting linkand a second line segment Lconnecting the pivot position Y on the boomof the bell crankand a pivot position W on a tilt cylinderis set in a range from 0 degree to 180 degrees on the attachmentside, the attachment can be selected from a plurality of types such as a bucketand a forkfor use, and each of the attachmentthat is different from each other has a different pivot position on the connecting linkrelative to the pivot position on the boomas a reference point.

In a work machine, an angle &#x3b8; formed by a first line segment Lconnecting a pivot position Y of a bell crankon a boomand a pivot position X of the bell crankon a connecting link, and a second line segment Lconnecting the pivot position Y of the bell crankon the boomand a pivot position W of the bell crankon the tilt cylinderon a bucketside is 176 (deg) or less, an angle &#x3b1; formed by the second line segment Land a line segment Lconnecting the pivot position W of the bell crankon the tilt cylinderand a pivot position Z of the tilt cylinderon a working structure is 72.3 (deg) or less, and, in a case where the bucketis set at a top position, a lowering angle &#x3c9; of a front end of a lower surface of the bucketis 4.5 (deg) or less.

Work machine

A temperature control system which performs control of an object whose temperature is to be controlled as accurately as possible. The system comprises: a chiller located in a fluid circulating and supplying system, for cooling a thermal fluid returning from a vacuum chamber, a first flow control valve located in the fluid circulating and supplying system in a position between the chiller and the vacuum chamber, a bypass passage for splitting and supplying thermal fluid returning from the vacuum chamber to a position between the first flow control valve and the vacuum chamber, before it reaches the chiller, a second flow control valve located in the bypass passage, and a halogen lamp heater located in the fluid circulating and supplying system in a position between a confluence point of the bypass passage and the vacuum chamber, for adjusting the temperature of the thermal fluid passing therethrough to a set temperature.
