Abstract: A glass block for a plasma resistant member, including silicon and at least one of magnesium and calcium, in which, in terms of mole percentage based on an oxide, a total content of MgO and CaO is 3.0 mol % or more and less than 29.0 mol %, a content of R2O is 3.0 mol % or more and less than 35.0 mol %, and a content of R12O is 8.0 mol % or less, provided that R1 is an alkali metal element and R2 is an alkaline earth metal element.

Abstract: A leaning vehicle includes an actuator, a left steerable front wheel, a right steerable front wheel, a steering mechanism and a leaning mechanism. The steering mechanism includes a first center steering shaft, a second center steering shaft disposed at the front side of the first center steering shaft, and a center steering shaft rotation interlocking mechanism that interlocks rotation of the first center steering shaft with rotation of the second center steering shaft. The actuator is provided between a left end and a right end of a link member of the leaning mechanism in the left-right direction. At least one part of the actuator is provided at a position that overlaps with a movable range of the center steering shaft rotation interlocking mechanism as viewed from the up direction or the down direction.

Abstract: A leaning vehicle includes a vehicle body, a left wheel, a right wheel, a leaning mechanism, a leaning drive mechanism and a leaning brake mechanism. The leaning drive mechanism includes a drive source. The leaning drive mechanism includes a gear, rotary shafts, and a gear casing member. The leaning brake mechanism includes a brake member and a resistance applying member. The gear and the rotary shaft of the leaning drive mechanism and the brake member of the leaning brake mechanism are supported by the vehicle body in a rotatable manner by way of the gear casing member of the leaning drive mechanism.

Abstract: A leaning vehicle includes a vehicle body; a rear wheel; a left arm mechanism; a left steerable front wheel; a right arm mechanism; a right steerable front wheel; a leaning mechanism; a leaning drive mechanism; and a steering mechanism. The leaning drive mechanism is disposed between any one of a left-right arm connection mechanism, the left arm mechanism and the right arm mechanism and the vehicle body. A rear end of the leaning drive mechanism is disposed at a rear side of a lower end of a steering shaft in the front-back direction of the vehicle body. A front end of the leaning drive mechanism is disposed at a front side of an upper end of the steering shaft. At least a portion of the leaning drive mechanism is disposed at a down side of the steering shaft in the up-down direction of the vehicle body.
